71 Particularly by reason of the reference made thereto by the primary judge to the effect that the same reflected the policy underlying the Access Agreement, it is lastly appropriate to set out below clause 13.3A.1 of Schedule 13:
"13.3A.1General
In relation to Preselection Implementation, resolution of the issue of the co-existence and interaction of Preselectable Services which are Preselectable Commissions and other Telecommunications Services (including other Communications which are or involve Preselectable Services) will be in accordance and consistent with the Government policy set out in the Telecommunications Act and in the following paragraphs of the letter from the Minister of Communications to AUSTEL dated 27 April 1993 ("the Minister's Letter"):
'In general terms, however, it is important that the ballot be as wide as practicable in its coverage.'
'Given that consumer interests as well as competition policy considerations are at the heart of this issue, the Government's policy position would require that where a customer has preselected a Carrier for a category of service, all that customer's calls in that category should automatically be carried by the preselected Carrier. This would be the case regardless of how those calls were dialled, unless the customer specifically chooses otherwise, such as by using override codes or by selecting a particular service that involves a variation to the preselection decision.'
'Customer's preselection decisions should not be frustrated or by-passed by any pre-existing arrangements with Telecom. For example, it seems to me that abbreviated dialling features associated with particular existing local exchange capabilities should in future deliver relevant calls automatically to the preselected Carrier, unless the customer overrides that selection on a case-by-case basis.'
…
'Any other outcome would seek to risk the bundling of services currently provided at the local exchange level (where competition will be slower to emerge because of structural and technological obstacles) with other services where competition is more immediately practicable. This would risk adverse effects on the emergence of competition. Such effects would be inconsistent with the intent of policy and the legislation.'"
Albeit that the Minister's letter had been written in the context of the intended ballot, there is no compelling reason to confine the policy there enunciated to that historical context.
Observations of the primary judge relating to what he described as the contents of the HomeLine Net service
72 The Telstra HomeLine Net service is an option designed for customers who have Internet access, which was introduced to residential customers on 1 March 2001. Customers are required to subscribe for the Telstra HomeLine Net service by ordering it on-line. Customers who subscribe for the Telstra HomeLine Net service also preselect Telstra for national long distance, international calls, and calls to mobile services from the HomeLine Net service. These subscribing customers agree not to acquire services from other carriage service providers by dialling the access override code of those carriage service providers, whilst still subscribing to the HomeLine Net service. Financial terms and conditions of subscribers for the HomeLine Net service involve a lower access charge than the Telstra monthly fixed telephone line access charge. As the primary judge explained, it is the agreement of HomeLine Net subscribers not to acquire services from other carriage service providers, by dialling the access override code of those carriage service providers, whilst they are still subscribing to the HomeLine Net service, which is the central element of controversy in these proceedings.
73 In order to subscribe for this Internet service, the customer undertakes access to the Telstra on-line product catalogue, and responds to a series of commands and requests. When doing so, the customer is prominently informed on a single screen image (or computer interface) as follows:
"HomeLine Net service customers must be preselected to Telstra for Long Distance calls and customers must make all STD, Calls to mobiles and International Direct calls through Telstra.
…
It is a term of this service that you agree to use Telstra for your fixed line calls and do not override to other carriers.
…
HomeLine Net Service is provided in accordance with the terms and conditions of Telstra's Standard Form of Agreement… available on the Internet at www.telstra.com.au/sfoa."
74 The relevant section of Telstra's Standard Form of Agreement is the "Public Switched Telephone Service" (PSTS) section, and the term which may reflect the customer's agreement not to use the access override code to acquire services from another carrier, to cite the primary judge, precisely, "emerges in a curious way". Clause 5 of that section deals with annual charges for the so-called "Basic Telephone Service", which includes the HomeLine Net service, and that part thereof extracted by his Honour reads as follows:
"5.1 The annual charges for:
…
(e) the following types of Non-Business Services:
…
· a HomeLine Net Service, which is a Basic Telephone Service available to Non-Business Customers who preselect Telstra for National Long Distance calls, International calls and calls to cellular mobile services from the PSTS and who:
(i) apply electronically for the HomeLine Net service over the Internet in accordance with the procedures notified by Telstra from time to time;
(ii) must agree not to acquire services from other carriage service providers by dialling the access override code for those carriage service providers while subscribing to the HomeLine Net Service; and
(iii) agree to receive the HomeLine Net billing service as described in clause 11.12 of this Section instead of Telstra's standard paper billing service;
…
are set out in Table 5.1."
Table 5.1 is a table setting out annual and monthly charges.
75 The primary judge next described the contractual consequences to a customer subscriber to the HomeLine Net service who uses the access override code to obtain the services of another carrier. Clause 10 of the General Terms and Conditions forming part of Telstra's Standard Form of Agreement governing its services, including the HomeLine Net service contains the following provisions as to suspension and cancellation of services:
"10.1 The Customer may cancel a service by notifying Telstra. Notice must be in writing unless the service is residential.
…
10.3 Telstra may suspend, limit or cancel a service if:
· The customer notifies Telstra in accordance with clause 10.1;
…
· The customer breaches the Standard Form of Agreement (including any of these General Terms and Conditions).
…"
Those General Terms and Conditions comprise 8 pages of printed material.
76 Another issue arising was described by the primary judge as concerning the means by which, both practically and legally, a customer can cancel a subscription to the HomeLine Net service. In the PSTS section of the Standard Form of Agreement, paragraph (a) of sub-clause 8.bb.6 provides as follows:
"Unless otherwise noted in relation to a particular HomeLine pricing package:
(a) the Customer may cancel an (sic) HomeLine pricing package at any time by notice to Telstra."
The Standard Form of Agreement extends over 252 pages of printed material. His Honour further observed in this context the existence of a restraint on a subscriber to the HomeLine Net service, from using the access override code, which was to be identified in marketing material distributed by Telstra. In versions of an advertising brochure promoting the service, and other services, as from 17 January 2001, the following is listed as one of HomeLine Net's features, which may be compared with what appears in [73] above:
"8. Available to most residential customers preselected to Telstra for long distance. Customers are not eligible for capped STD, Calls to MobileNet, the Telstra Neighbourhood Call and Telstra 25 option discounts. No override available."
77 The primary judge concluded his summation of the circumstances which attended Telstra's introduction of the HomeLine Net as follows (at [69]):
"I am satisfied that the Telstra employees developing the HomeLine Net service were proposing until early February 2001 that a subscriber to the HomeLine Net service would be prevented from making certain classes or types of calls by rendering it physically impossible for the calls to be made. This would have been achieved by physically preventing the subscriber from using override access. I am also satisfied that the decision to impose the contractual terms was made to achieve the same result. That is, the decision to impose the condition was made to stop a subscriber using override access. While there is no evidence directly linking the change of approach to the letters of complaint from solicitors acting for Optus, I am satisfied the preferable inference is that the letter of 1 February 2001 gave rise to the instruction to abandon the use of a bar. The sequence of events and the timing of the instruction would sustain such an inference and the failure of Telstra to call evidence demonstrating that the instruction was given for some other reason enables the inference to more readily be drawn."
Findings of the primary judge adverse to Telstra as to breach of what was described as the Tariff Obligations the subject of clause 13.3.7 of Schedule 13 of the Access Agreement
78 At the time of delivering reasons for judgment on 14 December 2001, the primary judge made a declaration to the effect that Telstra had breached the so-called tariff obligations the subject of clause 13.3.7 of Schedule 13 of the Access Agreement (reproduced in [69] above) by including as a term (the so-called "no override term") of subscribing to the HomeLine Net service that the subscriber agrees not to acquire services from other carriage service providers by dialling the override codes of those carriage service providers while subscribing to the HomeLine Net service. Subsequently on 28 February 2002, his Honour ordered that Telstra cease to offer the HomeLine Net service on what may be described as terms inconsistent with that declaratory relief. Telstra has sought leave to appeal against the grant of the declaratory and injunctive relief, in advance of the determination of a consequential award of damages against Telstra for breach of contract.
79 The primary judge's description of the HomeLine Net as a service is technically incorrect, so Telstra indicated by way of preliminary observation, in that the evidence disclosed that it comprises one of a range of options available for residential customers having a basic telephone or access line service, being options which together comprised the so-called "Telstra HomeLine Options", whereas a basic telephone or access line service is constituted by the line connection between a customer's premises and Telstra's public switched telephone service network. In fairness to the primary judge, the description "service" is attributable to Telstra's documentation provided to potential customers (see [73-74] above), but these reasons for judgment will mainly hereafter use the description "HomeLine Net" to avoid unnecessary controversy.
80 The process of reasoning by which the primary judge reached the conclusion, expressed in [103] of his reasons for judgment, that Telstra had breached clause 13.3.7 of Schedule 13 of the Access Agreement, "by offering the HomeLine Net service on the basis that a subscriber will not use override to access the services of Optus", may be summarised as follows:
(i) Although it is "tolerably clear" that calls comprising an Override Communication (the definition whereof is extracted in [68] above) are not comprehended by the Schedule 13 definition of Preselectable Services, so that clause 13.3.7 does not directly affect an override communication in the way in which it inhibits or prevents calls of the kinds which constitute Preselectable Services, nonetheless the HomeLine Net service does include Preselectable Services (ie national long distance calls, international calls and calls to mobile services), and the contentious condition (ie clause 13.3.7) is imposed (given the concession by counsel for Telstra rightly made that tariffing could include the imposition of a condition) on the acquisition of those services. In that regard, his Honour considered that clause 13.3.7 was not intended to have an unduly narrow operation, and that he was satisfied that the imposition of the condition constituted the "tariffing of Preselectable Services", and did so in an anti-competitive way.
(ii) The expression "Preselection process" where used in clause 13.3.7, is "probably a reference to Preselection as made available by either Carrier in their capacity as a Local Exchange Carrier" (the definition of Preselection is extracted in [66] above), "and if so, then it would include the service which would, relevantly, route Override Communications to the Override Carrier" (the definitions whereof are extracted in [68] above).
(iii) The contentious clause 13.3.7 would preclude, for example, Optus inducing a Telstra subscriber by competitive pricing or other means from spontaneously using override to access the Optus network for the purpose of making one or a number of trunk calls, and it would, in that way, deny Optus a commercial opportunity that the overall scheme of interconnection and preselection was designed to provide, and thereby remove the opportunity for Optus to seek customers, who may ultimately alter their preselection, by offering special rates on trunk calls accessed by override, and thereby to engage in a particular means of "rivalrous market behaviour" (the latter expression being borrowed from a decision of the Trade Practices Tribunal in Re Queensland Co-operative Milling Association Ltd; Re Defiance Holdings Ltd (1976) 25 FLR 169 at 188 (Woodward J presiding)), and "would also deny the subscriber the opportunity of taking advantage of the inducement offered by Optus".
(iv) A recurrent theme of the so-called "key objectives" of the implementation of Preselection, set out in clause 13.1.3 of Schedule 13 (extracted in [65] above), is customer choice, reference being made by the primary judge to the "choice process" theme of sub-clause (i) thereof in particular, and to the Government policy evident in clause 13.3A.1 of Schedule 13 (extracted at [71] above). Reference may be also added in this context to the "equal opportunity to designate" provisions of clause 13.1.2 of Schedule 13 (also extracted in [65] above).
Thereafter the primary judge concluded at [101] of his reasons for judgment that "[i]t appears to me that the tariffing of a product (even though selection of the product is the choice of the customer) that diminishes the capacity of one Carrier to offer choice is anti-competitive in the way contemplated by clause 13.3.7. I accept that a customer can fairly readily terminate the HomeLine Net service. However to do so would involve some active steps being taken and there could be, as the evidence revealed, some delay in termination being effected. The primary judge doubtless had in mind the cross examination of Telstra's officer Mr Walther. Spontaneous use of the override facility is effectively eliminated or at least substantially curtailed". In reaching that conclusion, the primary judge observed that his reasoning might raise a question as to whether either Telstra or Optus could offer Preselectable Services on terms that included a contractual term or period, so that a Carrier could not enter into an agreement with a customer that the customer would use the Preselectable Services of that Carrier for a specified period of time. His Honour further observed that "[i]t appears that, as a matter of fact, such provisions are commonplace", but that "it has not been suggested that the conduct of the parties under the Access Agreement bears upon its meaning, and its effect, in this context, was not the subject of submissions".
Telstra's submissions on findings of the primary judge as to breach of the Tariff Obligations
81 Telstra advanced the preliminary observation that it would be surprising if a clause in a schedule to the Access Agreement could have been intended to regulate in an ongoing way the competitive relationship between the parties in a manner that at least overlaps, and perhaps went further, than the regulations and regulatory regime imposed by the 1991 Act and the Trade Practices Act 1974 (Cth). In any event, Telstra's first principal submission on appeal was shortly to the effect that the "no override" term or condition of HomeLine Net did not involve the tariffing of Preselectable Services, simply because, as his Honour had accepted (see [80(i)] above), the defined expression "Override communication" (extracted in [68] above) is not one of the "Preselectable Services" within the definition of that latter expression. For that shortly stated threshold reason alone, Telstra asserted that the "no override" term did not involve the tariffing of Preselectable Services within the prohibition the subject of clause 13.3.7 of Schedule 13 of the Access Agreement. That submission appears to misconceive the significance of the circumstance that the "no override term" has been stipulated or imposed by Telstra as a condition of the grant or provision of those tariffed services which are the subject of the specified Preselectable Services of the HomeLine Net. Clearly enough, to provide a service on the condition that the person so provided does not acquire a similar service from a third party does not mean that the imposition of the condition involves the grant of a service per se, but the imposition of the condition becomes an aspect of the acquisition of that service which is actually so provided. That distinction was what the primary judge appears to have had in mind in the expression of his finding summarised in [80(i)] above.
82 Telstra then contended that contrary to the finding below, the HomeLine Net did not involve the imposition of the "no override" term on the acquisition of Preselectable Services, for the reason that the HomeLine Net provided for a telephone basic service for residential customers on prescribed terms and conditions, including monetary rates payable annually or monthly, as detailed in Mr Walther's affidavit, and a telephone basic service is not a Preselectable Service. For instance, the HomeLine Net customer may choose to make no outgoing calls, or might make only Local Calls. Moreover Telstra was said to have been offering numerous options, apart from HomeLine Net, for or relating to the provision of a basic telephone service. It was further said that HomeLine Net subscribers may acquire certain Preselectable Services, such as National Long Distance Calls (see [69(a)] above), which are supplied at standard rates contained in those parts of the Public Switched Telephone Service section of Telstra's Standard Form of Agreement which are concerned with those Preselectable Services, and similarly, customers who subscribe for options other than HomeLine Net, being options which do not contain the "no override" term, may also acquire Preselectable Services at these standard rates, or depending on the option chosen, at reduced rates. For those reasons, so Telstra submitted, the "no override" term in HomeLine Net is not a condition on the acquisition of any Preselectable Service, and the inclusion of the no override term in the HomeLine Net does not involve the tariffing of Preselectable Services within clause 13.3.7, which therefore has no application to HomeLine Net. Those contentions do not necessarily answer Optus' complaint that in the context of tariffing HomeLine Net to residential existing customers, whether or not they may already enjoy the benefit of a telephone basic service and some one or more services falling within a Preselectable Service category or categories, Telstra has engaged in the tariffing of certain services that do fall in any event within the defined meaning of Preselectable Services in an anti-competitive way, by reason of its imposition of the "no override" stipulation, whether in the context of customers' continuation of some one or all of the Preselectable Service categories, or the grant of some one or more thereof to existing customers in the context of "joining the HomeLine Net programme".
83 Telstra next submitted that in any event, the primary judge erred in concluding that Telstra breached clause 13.3.7 of Schedule 3 to the Access Agreement because his Honour made no finding that the "no override" term in fact undermined the integrity of the so-called Preselection process. So much may not have been stated by his Honour in so many words, but a finding to that effect reflects or underpins the conclusions of the primary judge summarised in [80] above. Telstra pointed out in any event that the clause 13.3.7 expression "Preselection process" was not a defined term, in contrast to Preselection per se (see [66] above), and that the word "process" should be given its common meaning, such as, according to The Macquarie Dictionary 3rd ed. 1999 at 1703, "a systematic series of actions directed to some end", or "a continuous action, operation, or series of changes taking place in a definite manner". Therefore, so it was further submitted by Telstra, clause 13.3.7 applies to tariffing that undermines the systematic series of actions, or continuous actions or operations directed to the rolling out, implementation and making available of the Preselection service, being actions provided for in Schedule 13, which concern:
(i) the conduct of the initial ballot of customers in ballot areas in Australia to enable them to nominate their Preferred Carrier, as between Telstra and Optus;
(ii) the provision of the interim "10" Carrier Selection Code arrangements for Optus services;
(iii) the development and implementation of the technical, operational and administrative systems within the networks of Telstra and Optus; and
(iv) the conditioning of those networks to make Preselection available in respect of Eligible Preselection Lines, and the cutover from the interim "10" Carrier Selection Code arrangements to Preselection.
84 Upon that footing, Telstra submitted that the "no override" term since imposed by HomeLine Net has not affected, much less undermined, the Preselection process, and further that the system by which Preselection has been implemented, and Preselection has been provided, remains unimpaired, whether or not a customer chooses to subscribe to HomeLine Net, and thereby agrees to the "no override" term. Telstra pointed out in the context of this submission that the Preselection process of Schedule 13 of the Access Agreement was created back at the time the Access Agreement was originally made, and was designed to address concerns that Telstra would adopt anti-competitive practices to convince customers to remain with Telstra, rather than select Optus as their preferred choice. The difficulty which that latter Telstra submission encounters is that the defined meaning of Preselection, comprising as it does a service in respect of a Preselected Line (see the definitions extracted in [66] above), inherently imports or implies the notion of a process, without limitation or confinement being expressed to circumstances prevailing at the time the Access Agreement was entered into, or up to the time of completion of the contemplated balloting in the ballot areas of Australia, following upon "the series of actions or the continuous actions or operations directed to the rolling out, implementation and making available of the Preselection service". It would reasonably be expected that if a temporal limitation had been mutually intended by Telstra and Optus as the parties to the Access Agreement in relation to anti-competitive stipulations such as clause 13.3.7, explicit provision would have been made in relation thereto, particularly in the context of what plainly purports to be implemented a highly complex and detailed contractual arrangement. The language adopted by clause 13.3.7 is of wide ranging import. There is not to be found elsewhere in Schedule 13, and in particular in the clause 13.2.1 definition of Preselection, the expression of an objective or intention to restrict or confine the ongoing scope or operation of clause 13.3.7 to the original ballot activities.
85 A further theme of submissions advanced by Telstra, being the most crucial in my opinion, was to the effect that the "no override" term of the HomeLine Net did not in any event involve the tariffing of Preselectable Services in an anti-competitive way, even if, as the primary judge concluded for reasons already summarised, the HomeLine Net, inclusive of the override term, involved the tariffing of Preselectable Services, and even if his Honour did not err in relation to the meaning of "Preselection process" contained in clause 13.3.7. In the context of the reasons for judgment of the primary judge summarised in [80(iii)] above, his Honour said that the issue to be determined was whether "the competition contemplated by 13.3.7 would allow one Carrier to offer, competitively, a product which, if accepted, would deny (temporarily) the customer the opportunity of accepting a product offered by the other Carrier and thus effectively deny that carrier the ability to compete". Telstra submitted that the issue arising, as so formulated (and resolved) by the primary judge, manifested a misunderstanding of the nature of competition, and in particular, involved a confusion of the process of competition with the end result of competition. It was said that rivalry in a commercial or business context takes the form of a competitor seeking to offer lower prices, better services or different services, from those offered by its competitors, for the purpose of inducing consumers to acquire goods and services from the first mentioned competitor to the exclusion of its other competitors, and well known passages concerning the nature of competition appearing in Queensland Co-Operative Milling Association at 188 (being additional to that cited in [80(iii)] above), and in Queensland Wire Industries Pty Ltd v Broken Hill Proprietary Co Ltd (1989) 167 CLR 177 at 191 were cited, being a nature described as "deliberate and ruthless". The end result of competition, on the other hand, so the Telstra submission continued, is the consumer making a choice as to which goods and services offered by competitors the consumer will acquire, being a choice by its very nature involving other suppliers not being successful in inducing the customer to acquire goods and services from them. The mere fact that by offering HomeLine Net, Telstra sought to have customers agree to acquire Telstra services, at least temporarily, rather than those of its competitors, could not, so it was submitted by Telstra, be regarded as anti-competitive. That proposition begs the question whether any such "mere fact" is constituted nevertheless by conduct of a carrier by way of undermining "the integrity of the Preselection process", irrespective of the employment of deliberate and ruthless means of engagement in competitive conduct. Put another way, clause 13.3.7 does not purport to proscribe a particular species of commercial or business activity, but rather the means by which the same is implemented or carried out.
86 Moreover, and further critically to the issue at hand, Telstra emphasised that HomeLine Net is terminable at will by any Telstra customer, without penalty as to cancellation charges, and that there is no minimum duration time of commitment or other restrictions imposed on a customer cancelling his or her subscription to HomeLine Net, Telstra making reference in that context to paragraph (a) of sub-clause 8.bb.6 in the PSTS section of Telstra's Standard Form of Agreement (extracted in [76] above). The HomeLine Net promotion was said by Telstra to have thus involved Telstra in merely seeking to induce a customer to choose to agree to use Telstra rather than Optus (or any other carriage service provider) until the customer might choose, or be induced to choose, otherwise, so much being said to be of the very essence of competition, indeed of fair competition. Telstra pointed to the affidavit testimony in the proceedings to the effect that the contractual provisions obliging customers to use the Preselectable Services of a single carrier are a predominant means of telecommunications competition, and thus for example, a carrier generally offers lower rates to customers who preselect it for certain Preselectable Services. Telstra referred further in this context to the practice of the Carriers, asserted to the primary judge to be "commonplace" in the Australian telecommunications market, of providing inducements to customers to agree, for example in the case of Optus, to acquire a single carrier's Preselectable Services for a minimum agreed term of at least 12 months (or suffer an early cancellation penalty), to which passing reference has already been made at the conclusion of [80] above. The tariffing of Preselectable Services upon minimum agreed terms of that dimension would not necessarily be anti-competitive, so Telstra contended, in contrast to terms which may operate in practice or reality to achieve customer patronage for an indefinite or uncertain duration. I would observe that the latter circumstance is precisely what has been at the forefront of the adverse consequences whereof Optus has seemingly complained, given the understandable reluctance of a customer to withhold from joining HomeLine Net to cancel HomeLine Net, merely because of a fetter upon the right to override for the time being for instance solely in relation to national long distance calls.
87 Telstra challenged the conclusion of the primary judge, referred to in [80] above, as to the preclusion of Optus, albeit temporarily, from offering choice, and the consequence, said to flow therefrom, that the supply of HomeLine Net containing the no override term was inherently anti-competitive. Telstra submitted that the override term did not affect Optus' ability to offer services, and a customer's choice to subscribe for HomeLine Net was simply the end result of successful competitive conduct on the part of Telstra, that conduct being Telstra's offering of inducements to persuade customers not to use the services of Optus (or of any other future carrier), by means of override (I interpolate to mention that it is perhaps more accurate to say that Optus' ultimate complaint goes more to "opportunity" rather than "ability"). Those inducements were said by Telstra to include the low monthly access prices included in the HomeLine Net "option", being comparatively lower prices doubtless because of customer patronage of the HomeLine Net services being required for the full range thereof. In any event, the no override term was asserted by Telstra to be part of the consideration that the customer agreed to give, in the exercise of his or her original choice, in return for the full range of benefits available under the HomeLine Net "option". It had always been open to Optus, so the Telstra submission continued, to offer customer choice, in the sense of offering services on terms that were equally or more attractive than those contained in the HomeLine Net option, in order to inducethose customers not to subscribe, or to cease subscribing, to HomeLine Net, and to subscribe instead to services that Optus supplies. Reference was made by Telstra to the primary judge's observation that Optus did not mount a case that it was unable to offer the same or a similar product to HomeLine Net, or that Optus could not compete with Telstra in relation to the sale of Preselectable Services. After citing paragraphs (g), (h), (i) and (j) of clause 13.1.3 of Schedule 13, extracted in [65] above, Telstra concluded its submissions in relation to clause 13.3.7 as follows:
"Contrary to the trial judge's conclusion, subscription to HomeLine Net and agreement to the no override term does not deny customers choice; rather it is an exercise of choice by a customer. In subscribing, a customer is choosing not to avail himself or herself of the override facility to make override calls whilst so subscribing. The trial judge's construction of clauses 13.3.7 so as to preclude the no override term in reality denies customer choice and prevents the customer from having the final say and having the opportunity to make an informed choice.The trial judge's construction of clause 13.3.7 is contrary to the agreed objective of the parties, is contrary to clause 13.1.3(j), and cannot be sustained."
88 A major difficulty with those Telstra submissions summarised in the preceding paragraph is the focus upon the customer's choice involved in taking up the HomeLine Net in the first place, as described in [72-76] above, rather than the incident or incidents governing the capacity or tendency of the customer to subsequently choose to alter his or her preselection from HomeLine Net in favour of one or more of the services of another carrier such as Optus, as the primary judge explained in his findings summarised in [80] above. As there indicated, the inhibition on that ongoing capacity or tendency of the customer, as asserted by Optus, was considered by the primary judge to diminish the opportunity of Optus to successively offer the choice of alternative preferred carrier for the time being in respect of some relevant service or services. The clause 13.3.7 notion of "Preselection process" is a generic description widely conceived, being implicitly intended to reflect the preceding provisions of Schedule 13, in particular, clauses 13.1.2 and 13.1.3(g), and also of the third paragraph of the Minister's letter of 27 April 1993 incorporated into clause 13.3A.1 thereof. In my opinion, a central theme of the "integrity of the Preselection process" thereby reflected was the availability at all times of a subscriber's uninhibited capacity or ability, in an economic sense, to activate the same, and a subscriber's likely objective appreciation of that circumstance, irrespective of his or her patronage for the time being of any one or more Preselectable Services provided by a Carrier.
89 Nevertheless Telstra contended that contrary to the conclusion of the primary judge, there is nothing contained in the Access Agreement, or in any underlying policy evident therefrom, or in the Minister's letter incorporated into clause 13.3A.1 of Schedule 13 extracted in [71] above, which demands the preservation of entitlement of uninhibited spontaneous use of the override facility in respect of any Preselectable Service by a customer, notwithstanding his or her choice, freely made, to subscribe to HomeLine Net, and to thereby choose to agree not to make any override call to acquire a replacement service from other suppliers (including Optus) whilst still so subscribing. Telstra emphasised that "… there is no obligation on customers not to make override calls, and it is the decision of a customer as to who should be its Preferred Carrier and whether or not to make override calls to another carriage service provider". That submission is not however at least wholly borne out by the text of the HomeLine Net condition set out in [73] above, that "[i]t is a term of this service that you… do not override to other carriers", albeit that a customer of HomeLine Net is not contractually inhibited from cancelling his total participation in the HomeLine Net without prior notice or at will.
Conclusion upon Telstra's alleged breach of the Tariff Obligations the subject of clause 13.3.7 of Schedule 13 of the Access Agreement
90 The primary judge was in my opinion correct in holding that Telstra breached clause 13.3.7 of Schedule 13 of the Access Agreement by making available the HomeLine Net package to subscribers containing the condition (extracted in [73] above) that they would not implement the override facility to access the services of Optus, at least for the reasons his Honour gave. The "Preselection process" the subject of clause 13.3.7 was not explicitly confined in operation in relation to the duration of the ballot programme referred to, for instance, by clauses 13.3A.1 and 13.5.3 of Schedule 13 (extracted in [70-71] above), and there is no basis in the text for implying any such confinement. The evident purpose and intent of clause 13.3.7 is the maintenance and preservation of fair competition between the Carriers in relation to their respective tariffing of Preselectable Services in an ongoing market for those services, which had previously been of course the monopoly of one of the Carriers (Telstra), being a telecommunications market where transactions of instantaneous implementation, and of short duration in execution, are a feature or characteristic, or potentially so. That the capacity to override a customer's selection for the time being was mutually accepted as an essential key to the establishment and maintenance of a competitive market in which the Carriers were to engage is to be seen in the provisions of the Access Agreement concerning the notions of Override Carrier and Override Communication (set out in particular in clauses 13.1.2 and 13.1.3 (extracted in [65] above)), and in paragraph (c) of the definition of "Preselection" (set out in [66] above). All that was consistent with what AUSTEL had earlier reported, namely that equal access could only be achieved by "Preselection with override dial codes" (see again the full text of [53] above). It was decided many years ago in the United States that a telephone company's switched network, required in order to connect with local distribution facilities and to offer competing services, was an essential facility, because without access to it, a prospective competitor could not compete in offering telephone services : MCI Communications Corp v American Telephone and Telegraph Co (1983) 708 F 2d 1081 [1982-3] Trade Cases 65,137.
91 It is readily apparent, from the text of clause 13.3.7 of Schedule 13, and in particular the expression "in an anti-competitive way", that the parties intended to create a mutually competitive environment, beyond and additional to the scope of Part IV of the Trade Practices Act 1974 (Cth), which would fulfil the "key objectives" of clause 13.1.3 of Schedule 13 (extracted in [65] above), and paragraph (g) thereof in particular. So much is further apparent from the incorporation of the text of the Minister's letter of 27 April 1993 into clause 13.3A.1 of Schedule 13, and the themes therein emphasised as to customer capacity to override selection as material to the objective of competition, without any exception explicitly stated in relation to pre-existing arrangements. The clause 13.3.7 expression "undermine the integrity of the Preselection process" is doubtless unique for a contractual instrument, but there was a substantial measure of commercial novelty or uniqueness in the implementation of the circumstances borne out of the decision of the Australian Government to partially privatise Telstra, involving of course, as those circumstances did, the entry of an initial competitor into what had previously been the "closed shop" of a Government enterprise for many decades, upon the basis of interconnected network facilities having their foundation in what was formerly the exclusive Telstra telecommunication structures (as to which see again [55-56] above). It is of course to be kept in mind, as the primary judge recognised, that "a customer can fairly readily terminate the HomeLine Net", and that upon any such termination being effected, the customer may forthwith preselect another Carrier, but the reality of human experience, involving the patronage of any existing service, is such that consumers sometimes, if not often, tend to be reluctant to change, or to be readily deterred from changing, the status quo of his or her choice of a service provider, particularly in the context of the modern phenomena of technological structures and mechanisms, the implications of which the customer may well not have fully comprehended or continued to comprehend. No illustration has been proffered by Telstra, of which I am aware, of an intended operation of clause 13.3.7, other than by Optus in relation to the kind or nature of circumstances presently in focus, and moreover Telstra has not pursued any case to the effect that clause 13.3.7 is void for uncertainty.
92 The controversial notion of "Preselection process", incorporated into clause 13.3.7 of Schedule 13, is to be interpreted and understood essentially in the light of, and not divorced from, the statutory definition of "Preselection", and also in the light of the statement of Government policy incorporated into the abovementioned clause 13.3A.1 of Schedule 13 and the examples or illustrations there incorporated, and there is no ambiguity said by Telstra to be inherent therein. Contrary to the submission of Telstra, the word "process" produces no qualification to the defined meaning of "Preselection", but merely imports the notion of procedure or course of action in relation thereto. The expression "Preselection process" in that context therefore connotes the process comprising or involving the making available, and the implementation, of Preselection capacity, to or in favour of a Service Customer. The "integrity… of the process", in the context of clause 13.3.7, imports the notion or idea of the viability and effectiveness of that process. It was earlier foreshadowed by the responsible Minister in 1991 that equal access by competing carriers could only be achieved by preselection with override dial codes (see again [53] above), being an objective also reflected in the carrier licenses issued to the presently litigating parties (see again [56] above). That is not to suggest of course that ability to compete, for instance in relation to price, was intended to be excluded (see again clause 13.13.12 of Schedule 13 extracted in [70] above), though not to the extent that Telstra first sought to implement (see [95(vi)] below). There is no good reason to doubt, in my opinion, that for Telstra to have stipulated to customers of the HomeLine Net that "[i]t is a term of this service that you… do not override to other carriers", operates to undermine the integrity of the Preselection process, and that the tendency or potentiality to do so has subsisted as a reality in the context of the telecommunications industry from the outset of Telstra's introduction of HomeLine Net, by virtue of at least the real possibility that some customers for the time being of the HomeLine Net may well be disposed not to bring to an end the otherwise perceived remaining financial advantages and benefits of continuing participation in the HomeLine Net, as a consequence of overriding to another Carrier for a discrete service or facility already stipulated in the HomeLine Net package. Moreover, as the primary judge pointed out, there could well be some delay involved in some circumstances in putting customer terminations of HomeLine Net physically in place. It is significant that clause 13.3.7 has been framed in the unspecific terms of "integrity of the… process", in order, I would infer, to encompass the subtleties of competitive behaviour which have the capacity for unfairness or taking unfair advantage, and thus the potential for deficiency in "integrity of the process", in the context in which the behaviour might take place. The dictionary notion of "integrity" imports inter alia soundness of moral principle and character, uprightness and honesty. The very circumstance that Telstra notified potential customers of the HomeLine Net from the outset, on a single screen image (see again [73] above) that to "override to other carriers" was forbidden as "a term of this service", serves in my opinion to undermine, albeit not necessarily of course to obliterate or destroy, the integrity of the Preselection process. Prospective telecommunication customers would not be expected, necessarily or entirely, to understand the implications of what Telstra informed perspective HomeLine Net customers in Telstra's lengthy printed Standard Form of Agreement described in [76] above, to which those customers were referred by the text of the single screen image summarising the HomeLine Net, and containing inter alia the "no override" stipulation. In that present context incidentally, "integrity" imports in my opinion notions of "unimpaired" or "undiminished".
93 The thrust of the approach to construction of the primary judge, recounted and summarised in [80] above, was therefore correct, and his conclusion on the clause 13.3.7 issue should be upheld. The language employed in the framing of clause 13.3.7 is of sufficiently wide and descriptive import to accommodatewhat may be described as the potential subtleties of a Carrier's means of tariffing Preselectable Services in an anti-competitive way. As I have foreshadowed, the integrity of the Preselection process is undermined in circumstances for instance where a customer of a particular Carrier is inhibited or likely to be inhibited, knowingly or unknowingly, from taking advantage of the override facility of the telecommunications system purportedly to maintain on foot an existing contractual arrangement with that Carrier for the supply of so-called Telecommunication Services or facilities. The concept of undermining the integrity of the Preselection process is the type of novel description one might expect to find in the context of the newly competitive environment of developing communication technologies involving an array of telecommunication services in the nature of the Preselectable Services. Clause 13.3.7 is in my opinion designed to obviate the subtlety of inhibitions imposed by a Carrier upon the freedom of a customer's choice of Preselectable Services for the time being obtainable in a dynamic market, wherein unfettered or uninhibited competition is mutually intended to be an essential precept for multifaceted services, and where pricing would be likely to be susceptible to the frequency of competitive and vigorously publicised change. It may be readily inferred from the text of clause 13.3.7 that the parties to the Access Agreement were not prepared to submit to regulation inter se only to the extent provided by Parts IV and V of the Trade Practices Act 1974 (as amended). Telstra's application for leave to appeal should be formally granted, but the appeal resulting from such grant of leave should be dismissed.
Issues raised by Optus on the Optus cross-appeal
94 In anticipation of Telstra being granted leave to appeal, Optus sought to raise five issues by way of cross-appeal against findings of the primary judge in favour of Telstra, those issues in the sequence presented being framed as follows:
(i) Whether Telstra breached its obligations to Optus under clause 13.5.3 of Schedule 13 to the Access Agreement, and under what was asserted to be the implied term arising therefrom, namely obligations to implement and make available preselection through Preselection Systems (the so-called "Preselection Availability Obligation"), for the reason that the obligations imposed on Telstra pursuant to clause 13.5.3:
(a) are enduring, and not temporarily limited, as held by the primary judge; and
(b) require Telstra to make override available in the sense that consumers may at any time freely choose to use override, both in a technical and contractual sense, rather than be contractually restrained from so choosing.
(ii) Whether Telstra breached its obligations to Optus under Clause 4.1 of the Access Agreement and clause 1.2.1 of Schedule 1 thereto, and under what was asserted to be the implied terms arising therefrom, namely obligations to provide certain call carriage services to Optus over Telstra's networks (the so-called "Access Service Obligation") for the reasons that:
(a) Telstra cannot be said to carry calls of customers where it has contracted with those customers to prohibit them from acquiring services from Optus; and which
(b) has the result that Telstra denied Optus the benefit of Telstra's obligations to provide relevantly the access services.
(iii) Whether Telstra breached its obligations to Optus under clause 1.5.3 of Schedule 1 to the Access Agreement (the so-called "Barring Obligation"), and under what was asserted to be the implied term arising therefrom, namely the obligation not to allow the barring of a customer's access to Optus override calls service, and in particular by allowing barring without observing customer neutrality.
(iv) Whether Telstra breached its obligation to Optus under clause 20.8 of the Access Agreement to act in good faith in relation to all matters relating to or contemplated by the Access Agreement (the so-called "Good Faith Obligation").
(v) Whether Telstra's representations to customers and potential customers, in the terms and conditions of the HomeLine Net and elsewhere, to the effect that "no override was available", constituted misleading and deceptive conduct within s 52 of the Trade Practices Act 1974 (Cth).
The extent to which any of such alleged breaches of the Access Agreement, or the statutory breach, might increase or widen the scope of damage claimed to have been sustained by Optus for breach of clause 13.3.7 would doubtless fall for consideration in the event of Optus succeeding on any of these additional five issues.
95 Before formulating its submissions upon these five issues, Optus advanced preliminary observations and references to the following aspects of the regulatory scheme:
(i) Schedule 13 of the Access Agreement envisages that competition for customers would occur within an agreed framework, that is, through the establishment and maintenance of Preselection, the definition whereof is set out in [66] above.
(ii) By clause 13.3A.1 of Schedule 13 of the Access Agreement, Telstra and Optus agreed that resolution in relation to the implementation of Preselection would occur in accordance and consistent with the government policy set out in the 1991 Act, and in the paragraphs of the Minister's letter to AUSTEL dated 27 April 1993 (as set out in [71] above).
(iii) Preselection has thus related to Preselectable Services, that is, certain classes of calls such as long distance calls, international calls and calls to mobiles.
(iv) Preselection described the mechanism by which a customer may choose Optus or Telstra as its Preferred Carrier (the definition whereof is set out in [67] above), and so acquire Preselectable Services from Optus or Telstra on a semi-permanent default basis, and having done so, also choose to acquire Preselectable Services from the other carrier on an immediate, but one-off, Override call basis, by dialling that carrier's Carrier Selection Code (in the case of Optus "1456").
(v) Alteration of the choice of Preferred Carrier is not instantaneous or always cost free (Optus referring thereby to testimony of Telstra's Mr Walther at transcript pages 76 and 76C, to which reference may also be made to his testimony at transcript page 76J); by contrast, an override call choice, in the absence of conditions (such as the Telstra "No Override Condition") is fleeting, and does not bind a customer in any ongoing or substantial way to acquire the services of a carrier. Requiring customers not to exercise an override choice for the period during which they may take Telstra as their default carrier (as the HomeLine Net service was said by Optus to require through the conditions imposed by Telstra on that service) removed the essential difference between those two features of Preselection.
(vi) The alternative to the No Override Condition was to ensure that customers were physically barred from acquiring any override call service from any carrier other than Telstra. The imposition of a physical bar in such a manner was Telstra's initial intention, and that course was subsequently abandoned after the letter sent by Optus' Solicitors to Telstra on 1 February 2001 (see the finding of the primary judge at [77] above).
Whether Telstra breached the Preselection Availability Obligation
96 The text of clause 13.5.3 of Schedule 13, so far as is directly material, is set out in [70] above. As indicated in para 54 of the Affidavit of Mr Waters (Solicitor for Optus), implementation of the preselection regime required Optus to incur "significant expense", because the Optus network was required to be conditioned to support preselection, implementation costs of the Ballot were required to be shared proportionately, as were the costs of conducting the Ballot (save as to the first $8 million, which had to be borne by Telstra), and advertising and marketing costs were incurred in relation to advertising preselection. Also the costs of educating the public about the introduction of competition were required to be shared between Telstra and Optus. Since the Ballot Nomination Dates, Preselections Systems have been established and maintained in all relevant areas of Australia.
97 The finding of the primary judge on the issue as to breach of the Preselection Availability Obligation, and his reasons therefor (set out at [93] below), were as follows:
"In my opinion, cl 13.5.3(a) served a specific and limited purpose. It was to ensure that before ballots of customers were conducted, both Optus and Telstra had in place the technical, operational and administrative systems that would enable the customer choice (of Preferred Carrier) to be given effect to while enabling the customer to access the network of the Override Carrier. It was in this sense that a Carrier (who was the Local Exchange Carrier) had to make available Preselection including a service which would route Override Communications to the Override Carrier. It was a provision intended to create the environment in which the choice of the customer would be an effective choice. I doubt that the provision was intended to create an enduring obligation on the part of each Carrier (but cf cl 13.3.9) though even if it was, it was to make available Preselection in the way discussed. That is, it was not intended to require each Carrier (in the present case, Telstra) to ensure that a customer would remain able to use Preselection in the sense of not agreeing not to use it or any aspect of it."
98 Optus submitted that the words "in place" in par (a) of clause 13.5.3 should be afforded an "enduring meaning", and were not to be limited to a particular date or time, for the reasons that the Access Agreement could not have intended that an essential element of the Preselection System could be unilaterally removed by a party as soon as it was in place, and the scope of the preselection regime, both technical and operational, is of an inherently enduring nature, as was said to be illustrated by the following provisions of Schedule 13 to the Access Agreement set out in [65] above, namely clause 13.1.1, containing as it does reference to "continuing arrangements relating to Preselection after initial implementation", and paras (h), (i) and (j) of cl 13.1.3 in particular, which speak of the importance of customers' freedom of choice of an informed nature. Reliance was also placed by Optus in that context upon clause 13.3.9 of Schedule 13, which expressed the mutual recognition of the parties that "the successful implementation and continued operation of Preselection depends on each of them complying fully and promptly with their obligations under [Schedule 13]".
99 The Optus submission is not supported literally by the terms of par (a) of clause 13.5.3, nor can it be rightly postulated that it does so implicitly in substance. The preferred view of the primary judge set out in the passage extracted in [97] above should be accepted, without necessarily the inclusion of the obiter view contained in the last sentence, involving as it does treble negatives. The terms of clause 13.3.9 of Schedule 13, to which his Honour referred, and which are set out below, are more likely to represent the mutually intended ongoing regulation of the relationship between the parties here specifically applicable, particularly in the context of the generality of expression of the critical clause 13.3.7 of Schedule 13:
"13.3.9 The Carriers recognise that the successful implementation and continued operation of Preselection depends on each of them complying fully and promptly with their obligations under this Schedule. In particular, the Carriers recognise the importance of ensuring that the designations of Preferred Carrier for Eligible Preselection Lines are correctly programmed into the relevant Local Exchange and that this work is undertaken promptly and its completion accurately reported to the ballot administrator and the Other Carrier. Accordingly, the Preselection Working Group will develop procedures which enable it to verify that designations of Preferred Carrier are being implemented correctly by a Local Exchange Carrier, and also to verify the other systems, procedures and conduct of each Carrier for compliance with the other requirements of this Schedule. These verification procedures must not be unduly administratively burdensome to the Carrier subject to the verification."
This first ground of cross-appeal brought by Optus, based upon clause 13.5.3 and par (a) in particular, should be dismissed.
Whether Telstra breached the Access Service Obligation
100 Optus described the elements of the Access Service Obligation of Telstra as follows:
(i) to provide "the requested Access Service" to Optus;
(ii) in particular, to provide one such Access Service - "Domestic PSTN Originating Access" - "for all Communications prefixed by a Carrier Selection Code".
That description purportedly picks up the defined expression "Access Service" appearing in [60] above, clause 4.1 of the "Access Service" segment of the Access Agreement (extracted in [61] above), and more specifically in the contention of Optus clause 1.2.1 of Schedule 1 (extracted in [64] above), which relates to Domestic PSTN Originating Access. The provision of an Access Service by Telstra to Optus was said by Optus to involve and require the carriage of a telephone call by Telstra from the calling number of a customer who is directly connected (Optus' emphasis) to Telstra's communications network to a point of interconnection (ie so-called POI) with Optus' network (as explained in par 32 of Mr Douglas' affidavit by reference to the context of that hypothetical customer having preselected Optus or dialled the Optus override code in respect of a preselectable call). In the context of the HomeLine Net, Telstra is the Access Carrier and Optus is an Interconnecting Carrier.
101 Optus submitted that it was clear from the definition of Domestic PSTN Originating Access, and Mr Douglas' explanation, that the provision by Telstra of Domestic PSTN Originating Access involved the necessary element of Telstra carrying the call from the calling party to an Optus POI, and not merely providing the technical capability to do so, and that therefore the primary judge erred in finding that the obligation the subject of clause 4.1 of the Access Agreement and of clause 1.2.1 of Schedule 1 thereto was limited to an obligation in the following terms expressed in his reasons for judgment at [82], namely
"… to provide the infrastructure (in a technical sense) to enable the Interconnecting Carrier to use the network and facilities of the Access Carrier to meet the Interconnecting Carrier's obligations to its customers to carry communications from one point to another."
As mentioned above at [100], in the context of this litigation of course, Optus is the Interconnecting Carrier and Telstra is the Access Carrier. Optus submitted that Telstra's conduct constituted a direct breach of clause 4.1 and of clause 1.2.1 of Schedule 1, because Telstra could not be said to provide Domestic PSTN Originating Access in respect of customers whom it had contractually prohibited from being able to use any of the Optus services that would require Telstra to provide Domestic PSTN Originating Access to Optus. Further or in the alternative, Optus submitted that Telstra's conduct complained of breached Telstra's implied obligation to give Optus the benefit of clause 4.1 and clause 1.2.1 of Schedule 1.
102 Optus thereafter criticised the following finding of the primary judge which was consequential upon that already extracted above:
"The benefit the Interconnecting Carrier derives from cl 4.1 is access to the network and facilities of the Access Carrier which enables it to provide or offer a range of telecommunications services to its customers or potential customers."
Optus asserted that the foregoing analysis confused the benefits conferred on Optus with the requirement under the Access Agreement for Telstra to provide Interconnection Services that would enable Optus to have access to the network and facilities of Telstra. The expression Interconnection Service is defined by the Access Agreement as:
"a service for the provision of Interconnect Conditioning, Interconnect Capacity, Network Conditioning and Network Capacity to enable, or for use in, as the case may be, the provision of one or more Access Services."
Optus pointed out that access on its part to the Telstra network and facilities was a necessary input for Optus to be able to deliver services to its customers, but asserted that access alone did not satisfy Telstra's obligations to provide Optus with "Access Services".
103 Thus Optus contended that the primary judge, having found (as above stated) that the ultimate benefit conferred on Optus by clause 4.1 was to enable Optus to provide or offer a range of telecommunications services to its customers or potential customers, his Honour should have considered the specific nature of the entitlement conferred on Optus by clause 1.2.1 of Schedule 1. Optus submitted that the sole commercial benefit conferred upon it by Telstra's requirement to provide Domestic PSTN Originating Access pursuant to clause 1.2.1 was the ability to provide Preselectable Services to customers who were directly connected to Telstra's network, and who were chosen either to Preselect Optus as their so-called "default carrier" for all Preselectable Services, or who chose to override to Optus on a call by call basis for Preselectable Services by dialling the Optus "1456" Carrier Selection Code. Accordingly, so the Optus submissions continued, by introducing the condition in the HomeLine Net tariff that HomeLine Net customers must agree to not "override to other carriers" (see [73] above), Telstra intended to achieve the same result as under its original proposal to technically bar the use of override by HomeLine Net customers (as to which see the finding extracted in [77] above). As Optus further submitted, although customers were technically still able to breach the HomeLine Net conditions and use Optus' "1456" Carrier Selection Code, Telstra expected and encouraged its HomeLine Net customers to believe that this was not possible, and the evidence in the proceedings below indicated that Telstra expected that most of its HomeLine Net customers would consider that it was not possible to override by dialling the "1456" Optus Carrier Selection Code.
104 The Optus contention as to breach of the Access Service Obligation necessarily involved the conceptually difficult proposition that the imposition by Telstra of a contractual fetter upon third parties, being its HomeLine Net customers for the time being, was capable of constituting a denial of access by its competitor Optus as Interconnecting Carrier to the network and facilities of Telstra as the Access Carrier.
105 In arriving at his conclusion in favour of Telstra on the Preselection Availability Obligation, the starting point of the primary judge was to characterise the direction of the Access Agreement as being essentially to the interconnection of the networks of Optus and Telstra, and to the means of dealing with their co-dependency once interconnection had been achieved, and thus generally to creating the environment, including technical environment, in which Telstra and Optus could compete while being nevertheless co-dependent. The primary judge then referred to the conditions imposed by clause 4.1 to the provision of Access Service. The first two of such conditions, reflected in the opening line of clause 4.1, predicated in his Honour's view the obligation to provide Access Service upon prior interconnection and agreement on the terms and conditions of that interconnection, being a service to be provided by the Access Carrier to the interconnecting Carrier, the latter having complied with the relevant Service Ordering Procedures, defined by the Access Agreement as "… the procedures governing the forecasting, planning and ordering of relevant Services as set out in schedule 2". Those procedures in effect require the Interconnecting Carrier to give six and twelve month forecasts to the Access Carrier for the latter's planning purposes. Thereafter his Honour concluded at this point of his reasoning at [82], as extracted above at [101], that "… the obligation on the Access Carrier is to provide the infrastructure (in a technical sense) to enable the Interconnecting Carrier to use the network and facilities of the Access Carrier to meet the Interconnecting Carrier's obligations to its customers to carry communications from one point to another". In this context, reference may be repeated to the definitions "Access Service" and "Interconnection Service" set out in [60] above, and to the observation there made that the Access Agreement set up a framework for the provision of those services. The primary judge described at [85] the benefit which the Interconnecting Carrier derives from clause 4.1 as "…access to the network and facilities of the Access Carrier which enables it to provide or offer a range of telecommunication services to its customers or potential customers".
106 The conclusion of the Full Court upon the issue arising under this second ground of cross-appeal of Optus is that the primary judge correctly determined that the Interconnecting Carrier (Optus) was not contractually deprived of the benefit of Clause 4.1 of the Access Agreement, and of clause 1.2.1 of Schedule 1 thereto, in circumstances where the Access Carrier (Telstra) might induce its customers, upon the footing of a contractual commitment to Telstra, not to use an aspect of the facilities for the time being available both for the benefit of the customers of Optus as Interconnecting Carrier and also for the benefit of the customers of Telstra as Access Carrier. That conclusion of contractual interpretation follows, notwithstanding the imputed existence of any implied duty to co-operate attributable to Telstra, to ensure that Optus would have the benefit of those clauses 4.1 and 1.2.1 concerning access by its customers or potential customers to network facilities, since that benefit did not operate adversely to or to the exclusion of Telstra's contractual rights and entitlements for the time being derived from the subscribers to the HomeLine Net. The so-called duty to co-operate, discussed in the judgment of the Court of Appeal of the Supreme Court of New South Wales in Australis Media Holdings Pty Ltd v Telstra Corporation Ltd (1998) 43 NSWLR 104 at 124-125, does not operate to subvert or displace Telstra's contractual entitlements, otherwise validly subsisting in the circumstances postulated, but of course as has been earlier determined in these reasons for judgment, Optus is entitled in principle to obtain the substance of the redress it substantially seeks by recourse to clause 13.3.7 of Schedule 13 of the Access Agreement, for the reasons earlier provided in the segment "Conclusion upon Telstra's alleged breach of the Tariff Obligations of clause 13.3.7 of Schedule 13 of the Access Agreement". This second ground of appeal raised by Optus should therefore be dismissed.
Whether Telstra breached the Barring Obligation
107 The Barring Obligations asserted by Optus to have been breached by Telstra is contained in clause 1.5.3 of Schedule 1 to the Access Agreement which has been set out in [64] above. To that clause may be added reference to clauses 1.5.4 and 1.5.5 of Schedule 1 reading as follows:
"1.5.4 A customer may request the barring of national and/or international switched direct dialled trunk calls by contacting either Carrier. If the Access Carrier is contacted, the Interconnecting Carrier will notify the Access Carrier of the customer's request. The Access Carrier may contact the customer before implementing the barring for the purpose of confirming the request. The Carriers will negotiate agreed scripts to be used for this customer contact process.
1.5.5 Except where the customer has requested service specific barring, the Access Carrier must not implement service specific barring (such as barring of access for national or international switched direct dialled trunk calls) if it also blocks access to the Interconnecting Carrier's Network, without first obtaining the consent of the Interconnecting Carrier."
Clause 1.5.3 deals with barring where the bar has been requested by a customer, and clause 1.5.5 deals with bars that are independently initiated by either carrier, without being precipitated by a customer request for the bar. Telstra's Mr Douglas testified that barring means that customers can be prevented from making certain calls from their telephone service, and that a bar can be created by Telstra raising appropriate commands in its IT system, which in turn sends a command to the local access switch, where the barring would be applied; such a bar constitutes a physical or electronic frustration of the call.
108 The findings of the primary judge upon Optus' assertion as to breach of clause 1.5.3 are set out below:
"88. In my opinion, what cl 1.5 means is tolerably clear and its operation was intended to be limited. Clause 1.5.3 concerns a request to bar switched direct dial trunk calls which must be implemented by the Access Carrier to stop switched direct dial trunk calls (national and/or international) being made over the network of either Carrier. The mechanism established to achieve that result depends on who the customer contacts. Clause 1.5.4 sets out the mechanism. While on one view, cl 1.5.5 deals (differently) with the same subject matter as cl 1.5.3/.4 (barring of access for national or international switched direct dial trunk calls), it is appropriate to construe the clause to give meaning to all parts and arrive at a construction resulting in internal harmony. The better view is that the expression "service specific barring" in cl 1.5.5 is intended, as counsel for Telstra submitted, to cover at least a request that the override facility, as it might apply to trunk calls, be rendered inoperative.
89. The direct benefit conferred on Optus by cl 1.5.3 is that it will not carry trunk calls of a customer who has requested that such calls be barred. In this way the provision ensures that Optus will not be exposed to commercial risk (such as a customer refusing to pay for trunk calls carried over its network notwithstanding that the customer had made a request to bar such calls) because Telstra failed to perfect a request to bar them.
90. I accept that the decision of Telstra to impose a condition that a subscriber to HomeLine Net not use the override facility was adopted because the proposal to bar the use of that facility (and calls made using it) was abandoned in the face of complaint by solicitors acting for Optus. However the fact that this was the genesis of the decision does not, in my opinion, sustain the conclusion that the imposition of the condition deprives Optus of the benefit of cl 1.5.3. As just discussed, the benefit is more limited. Had Telstra proceeded with its original proposal and, as a result, a subscriber expressly or impliedly requested the barring of calls using the override facility by subscribing to HomeLine Net, an issue could have arisen about the operation of cl 1.5.5. However that proposal was abandoned."
109 Optus has submitted that by introducing the contractual "no override" condition of the HomeLine Net (see again [73] above), Telstra intended to achieve that which clause 1.5.3 of Schedule 1 to the Access Agreement prohibited Telstra from doing by means of a technical bar, and that in the absence of any evidence to the contrary, the primary judge was wrong in concluding that such conduct did not deprive Optus of any benefit conferred upon it by clause 1.5.3. Optus further submitted that the restriction on the ability of Telstra's customers to use Optus' Preselectable Services whilst being free to use Telstra's corresponding services, achieved by the inclusion of the no override condition, was exactly the sort of discriminatory outcome from which clause 1.5.3 was intended to protect Optus.
110 The Full Court is persuaded however that the reasoning of the primary judge is correct, and that in particular clause 1.5, which is headed "Disconnection and barring Procedures", is more limited in scope than Optus contended below and on appeal. Clauses 1.5.3-1.5.5 are literally concerned only with technical barring, that is, the conditioning of a network so as to bar certain calls from a customer's service. Moreover Telstra is correct in its contentions that the premise of clause 1.5.3 is a general request that all switched direct dial trunk calls be barred, and that such request is not concerned with who should carry such calls, but rather that such calls not be allowed at all. Clause 1.5.4 stipulates for the giving effect of the bar pursuant to clause 1.5.3, depending on whether the Access carrier or the Interconnecting Carrier is contacted by the customer. Unlike clause 1.5.3, clause 1.5.5 is not concerned with a general request for the barring of switched direct dialled trunk calls, but rather with a customer's request for "service specific barring". This third ground of cross appeal raised by Optus should also be dismissed.
Whether Telstra breached the Good Faith Obligation
111 This obligation was asserted by Optus to be based upon clause 20.8 of the Access Agreement, which is extracted in [62] above. The primary judge dismissed this cause of action propounded by Optus for the reasons set out below:
"106. What might be the outer reaches of the operation of cl 20.8 need not be explored in these proceedings… It need not be explored because on the second day of the hearing counsel for Optus provided particulars of the allegation of lack of good faith after an issue arose about what was alleged. Those particulars stated that it was neither fair nor reasonable for Telstra to deprive Optus of the benefit of the provisions already discussed namely cll 4.1, 13.5.3(a) and 1.5.3 and in doing so Telstra failed to act in good faith. As I have already discussed, I do not accept that these provisions confer the benefits contended by Optus. It would appear to follow that the allegation of want of good faith, as particularised, must fail."
Clause 4.1 of the Access Agreement (and as presented by Optus in argument on the cross-appeal combined with clause 1.2.1 of Schedule 1), relates to the so-called Access Obligation and clause 13.5.3 (to Schedule 13) and clause 1.5.3 (to Schedule 1) relate respectively to the so-called Preselection Availability Obligation and Barring Obligations.
112 Optus drew attention to authorities, in the context of which obligations of good faith and also of reasonableness have been implied in relation to the exercise of contractual rights and the performance of contractual obligations, the most recent being the decision of the Court of Appeal of the Supreme Court of New South Wales in Burger King Corporation v Hungry Jack's Pty Ltd [2001] NSWCA 187 (Sheller, Beazley and Stein JJA), where it was held that in circumstances in which certain contractual arrangements, principally involving a franchise for a term of 15 years, imposed an "extraordinary range of detailed considerations" regulating all or most aspects of routine and procedure, including staff presentation and vocabulary, an implied duty of good faith and reasonableness should operate to restrain one party from terminating those arrangements for insignificant breaches thereof. Earlier, the majority of a differently constituted Court of Appeal (Priestley and Handley JJA) in Renard Constructions (ME) Pty Ltd v Minister for Public Works (1992) 26 NSWLR 234 had recognised that an implied duty to act reasonably may be attributed to a contracting party in relation to the exercise of contractual rights and powers. The context in Renard was that contractual authority had been conferred on the Minister to take over the whole or any part of the construction work the subject of contractual arrangements, and to cancel the same, in circumstances of default by the contractor Renard in the performance or observance of any covenant or condition. Subsequently in Alcatel Australia Ltd v Scarcella and Others (1998) 44 NSWLR 349, the Court of Appeal (Sheller, Powell and Beazley JJA) adopted a similar approach in principle to that taken in Renard, by confirming the existence of a general principle that an implied duty of good faith, both in the context of performing obligations and of exercising rights, may be imposed upon contracting parties. The principles emerging from both of those authorities were subsequently applied by the Court of Appeal in Burger King with dramatically adverse consequences to the franchisor.
113 The attribution of duties of good faith and/or reasonableness in contractual settings has also been undertaken in this Court. As pointed out in Alcatel, the approach in principle there taken was in line with dictum of Finn J enunciated at first instance in Hughes Aircraft Systems International v Airservices Australia (1997) 76 FCR 151 at 193-197. There is a forensic complication in transposing those principles of implied obligation to the operation of the Telstra/Optus Access Agreement by reason of clause 20.8 thereof, which explicitly requires each party to act in good faith in relation to the other in relation to "all matters relating to or contemplated by this agreement". Clause 20.8 makes no reference to acting reasonably as well as in good faith, given that those concepts, albeit overlapping, are not identical. It is one thing to affirmatively exercise a power of termination of a contract for breach, in relation to which a requirement of good faith is more readily attracted, as exemplified in Renard and Burger King, but quite another for a contracting party to undertake a course of action, in its own commercial interests, which does not constitute breach of contract, but which, for instance, may nevertheless confer a competitive advantage upon that contracting party to the commercial disadvantage of the other contracting party. What constitutes unreasonable conduct or conduct lacking good faith in the exercise of contractual rights or obligations will or course vary according to the setting or circumstances of the particular contractual relationship. Conceptually, it would be unusual for conduct to be so characterised in the case of exercise of contractual obligations, which is the difficulty Optus faces in the context set out below.
114 Optus furnished the following particulars of Telstra's alleged breach of Clause 20.8:
"1. The Access Agreement obliges Telstra to provide to Optus the service of carriage of communications initiated by customers who are directly connected to the Telstra network and who dial Optus' access code from the customer's line to the point of interconnection with the Optus network (clause 4.1 and Schedule 1.1.2).
