Background
6 On 4 November 2016, Glencore notified the ACCC under s 44S of the Competition and Consumer Act 2010 (Cth) (CCA) of an access dispute in relation to the declared shipping channel and berthing services at the Port of Newcastle provided by PNO, which activated the ACCC's arbitration powers under Pt IIIA of the CCA. The dispute concerned the rates of the navigation service charge and wharfage charge levied by PNO in respect of the shipping channel service and berthing service respectively, and terms related to the imposition of those charges. Ultimately, though, the parties were agreed as to the rate of the wharfage charge.
7 On 18 September 2018, the ACCC made a final determination of the dispute under s 44V of the CCA. Two aspects of the determination should be noted. First, the ACCC determined an initial arbitral price for the navigation service charge as at 1 January 2018 of $0.6075 per gross tonne, which represented a significant decrease below the rates that had been charged by PNO since 2015. Clause 1.2 of the ACCC determination provided that the navigation service charge and wharfage charge, as determined by the ACCC, would be backdated so as to apply from 8 July 2016 with interest being payable on any amount overpaid to PNO by Glencore having regard to the ACCC determination. Second, the ACCC determined that the navigation service charge would apply in respect of vessels using the shipping channel service in two circumstances:
(a) where Glencore, either directly or by agent, charters a vessel to enter the Port precinct and load Glencore coal; and
(b) where Glencore makes a representation to PNO of the kind referred to in s 48(4)(b) of the Ports and Maritime Administration Act 1995 (NSW) (PMA Act) that it has the functions of the owner of a vessel, or accepts the obligation to exercise those functions, in order to enter the Port precinct and load Glencore coal.
8 On 8 October 2018, PNO filed an application for review of the ACCC determination pursuant to s 44ZP of the CCA (ACT 2 of 2018). On 9 October 2018, Glencore also filed an application for review (ACT 3 of 2018). By virtue of s 44ZO(1) of the CCA, the determination of the ACCC did not come into effect (by reason of the applications for review made to the Tribunal).
9 On 30 October 2019, the Tribunal (constituted by Middleton J, Mr R Shogren and Dr D Abraham) made a determination under s 44ZP of the CCA by which it varied the determination of the ACCC in two respects. The first concerned the amount of the navigation service charge. In that respect, the Tribunal determined an initial arbitral price for the navigation service charge as at 1 January 2018 of $1.0058 per gross tonne, which represented an increase to the rates that had been charged by PNO. The second concerned the description of the vessels using the shipping channels that were within the scope of, and were able to benefit from, the determination. In that respect, the Tribunal confined the determination to circumstances where Glencore, either directly or by agent, charters a vessel to enter the Port precinct and load Glencore coal. The Tribunal's determination was published as Application by Port of Newcastle Operations Pty Ltd [2019] ACompT 1 (Application by Port of Newcastle Operations).
10 Glencore applied to the Full Federal Court for judicial review of the Tribunal's arbitral determination in respect of both the level of the navigation service charge and the scope of the determination. On 24 August 2020, the Full Federal Court set aside the determination of the Tribunal and remitted the applications to the Tribunal for re-determination according to law. The Full Federal Court concluded that the Tribunal's decision with respect to the navigation service charge and the scope of the determination were affected by errors of law: see Glencore Coal Assets Australia Pty Ltd v Australian Competition Tribunal (2020) 280 FCR 194.
11 PNO appealed the Full Court decision to the High Court. On 8 December 2021, the High Court delivered its judgment on the appeal. In respect of the navigation service charge, the High Court upheld PNO's appeal and effectively reinstated the Tribunal's arbitral determination of the initial navigation service charge of $1.0058 per gross tonne (as at 1 January 2018). In respect of the scope of the determination, the High Court accepted PNO's appeal in part and dismissed it in part. The High Court concluded as follows (at [104]-[111], references omitted):
104 The Declaration, it will be recalled, relevantly described the Service as "the provision of the right to access and use the shipping channels (including berths next to wharves as part of the channels) at the Port". Plainly, the introductory reference to "the provision of the right to access" is surplusage. Having regard to the structure of the definition of "service" set out in s 44B of the Act, the service declared by the Declaration is "the use" of an infrastructure facility constituted by the shipping channels, which are treated for the purposes of the Declaration as including the berths.
105 In circumstances where Glencore wants to ensure that it can continue to enjoy the economic benefit that it unquestionably gets from the ability of ships, loading and carrying the coal that it sells to overseas buyers, to use the shipping channels and berths at the Port, Glencore is a person who wants "access" to the Service. Glencore is thereby a "third party". By operation of the Declaration, Glencore as a "third party" has a right to negotiate with PNO about the amount of the navigation service charge that PNO might fix for the Service. That is so whether Glencore sells FOB or CIF.
106 By exercising the right to negotiate through notifying an access dispute about the amount of the navigation service charge payable in respect of ships carrying the coal that it sells to overseas buyers either FOB or CIF, Glencore became entitled to an arbitrated bilateral outcome. The outcome to which Glencore became entitled was no less than could have been achieved without arbitration had PNO been willing to reach an agreement with Glencore about the amount of the navigation service charge payable by Glencore as permitted under the provisions of the PMA Act.
107 The Full Court was, on that basis and to that extent, correct to conclude that the Tribunal had erred in law in treating the permissible scope of the Final Determination as confined to circumstances where Glencore exercised some measure of control over the physical activity of moving a vessel through a shipping channel. The Full Court was therefore correct to set aside the Tribunal Decision and to remit the matter to the Tribunal for redetermination of the Final Determination.
108 Equally, however, the arbitrated outcome to which Glencore became entitled by exercising the right to negotiate was no more than could have been achieved without arbitration had PNO been willing to reach an agreement with Glencore about the amount of the navigation service charge payable by Glencore as permitted under the provisions of the PMA Act. The Full Court would have been incorrect to the extent that its additional observations, already quoted, might indicate that the Tribunal's re-arbitration of the access dispute could result in a determination governing the circumstances in which PNO would seek and accept payment of the Navigation Service Charge from a person other than Glencore in respect of the particular use of the shipping channels by a particular ship carrying coal sold by Glencore.
109 Subject to the constraints of tort and competition law, and to the provision of contractual consideration, one person can ordinarily enter into a binding contract with another person about the price at which that second person will offer a service to a third person. The third person will then become liable to pay the price to the second person under a separate contract that will be formed between the second person and the third person if and when the offer is made and accepted.
110 Here, however, the terms of the PMA Act do not permit PNO to enter into that kind of bilateral arrangement having potential consequences for a third person. It will be recalled that s 67 of the PMA Act relevantly goes no further than to permit PNO to enter into an agreement about the amount of the navigation service charge with a person who is liable to pay the navigation service charge. Absent any other person with a sufficient interest having chosen to become a party to the arbitration of the access dispute between PNO and Glencore, the only person who has the potential to become liable to pay the Navigation Service Charge as a result of the Final Determination is Glencore. When Glencore sells FOB, Glencore can answer the description of a person who is liable to pay the Navigation Service Charge only by acting to bring itself within the extended meaning of "owner" of a vessel in s 48(4)(b) of the PMA Act so as to accept the obligation to pay the Navigation Service Charge.
111 The Tribunal on remitter must therefore be confined to determining the circumstances in which the Navigation Service Charge will be payable by Glencore to PNO. In respect of the particular use of the shipping channels by a particular ship carrying coal sold by Glencore, the concern of the Tribunal will be to work out a practical mechanism to govern when and how Glencore will invoke s 48(4)(b) of the PMA Act to represent to PNO that it accepts the obligation to pay the Navigation Service Charge.
12 The High Court varied the orders of the Full Court such that the remitter to the Tribunal is confined to re-determining the scope of the navigation service charge (that is, the description of the vessels using the shipping channels to which the navigation service charge is applicable).
