The construction of cl 14.1(a)
21Clause 14.1(a) commences with an unqualified statement that "either" party may "terminate" the agreement "at any time". It then describes how that may be done - during the first 2 years of the agreement and "thereafter". A longer period of notice is required in the first period so as to provide secure employment for at least the first year. The notice given in that first period must be "not less than" 12 months. That language permits the party giving the notice to choose a longer period. How long that notice might be depends on whether it must expire in the two year period. If it can expire after that period, it is necessary to consider whether the exercise of the power to fix the period of notice was subject to any implied constraint.
22The right to terminate the agreement is given to "either" party. As Starke J observed in Currie v Glen [1936] HCA 1; 54 CLR 445 at 453, "either" is "a distributive word, and may mean one of two, or each of two - depending on the subject matter and the context. A common grammatical illustration will suffice: 'You can take either side', that is one side or the other; 'The river overflowed on either side', that is on each side." See also per Lindley MR in In re Pickworth [1899] 1 Ch 642 at 648 and Gibbs CJ in Fisher v Fisher [1986] HCA 61; 161 CLR 438 at 447. Here what is conferred is the right to do a unilateral act, namely to terminate at any time. That right is given to each party in the sense that it can be exercised by one or the other. That is not, however, the end of the inquiry, for here the question is whether where one party has acted unilaterally to "terminate", the other may also exercise the right do so, or whether the right, once exercised, is to be regarded as exhausted. The appellant argues that because termination involved the giving of a notice which brings the agreement to an end on its expiry, cl 14.1(a) continues to apply during that period and to permit a valid termination, in the same way that cl 14.2 continues to apply during that period and would permit the employer to terminate for cause with immediate effect.
23During the first two years of the agreement what must take place is "not less than 12 months prior written notice". That language could be read as meaning that the period of notice, and not merely the notice, must be given during the first two years. That would require that the notice expire in that period. On the other hand, if cl 14.1(a) is read as meaning only that the notice be given during that period, it permits notices to be given which would expire in or after that period. That in turn leaves open the possibility of a second and shorter notice being given, either in or after the first period. A second notice, if valid, would bring forward the date on which the agreement comes to an end. That is the position which the appellant argues for. The possibility of more than one notice being given and having that effect also exists if cl 14.1(a) is read as requiring that the notice expire in the period in which it is given.
24There is a fairly clear indication in the text that cl 14.1(a) is to be understood as requiring only that the notice be given in the relevant period. The clause enables either party to terminate "at any time". Terminate means to bring to an end. As used in cl 14.1(a), the word describes the act or process of terminating rather than merely the consequence or outcome of that act or process. It is only if it is used in that sense that it is possible for either party to terminate "at any time". What is referred to is or includes the giving of a written notice. If the notice period has to expire during the period in which the notice is given, it would not be possible to give a notice in the second year of employment because of the requirement that the notice be for "not less than" 12 months. That would be contrary to the unqualified statement as to the entitlement of either party to terminate "at any time".
25Reading cl 14.1(a) as so providing, it enables a notice to be given in the first period provided that it is "not less than" 12 months. The appellant suggests that by giving such a notice one party could bind the other to a further term of "5 years, 10 years, 20 years or more". It argues that reasonable business people in the position of these parties were not to be taken to have intended such a commercially unlikely outcome. It submits that outcome is one that could be avoided if cl 14.1(a) is construed as permitting more than one notice to be given. This argument makes it necessary to consider whether so read, cl 14.1(a) would permit the giving of such long notice periods.
26The power to fix a period of "not less than" 12 months is conferred for the purpose of giving advance notice of the termination of the agreement. Where a contractual power is given to one party for a purpose but in terms wider than necessary for the protection of its legitimate interests, the exercise of the power may be constrained by implied obligations of reasonableness and good faith, as was held in relation to the exercise of the powers given in the agreement in Burger King Corporation v Hungry Jack's Pty Ltd [2001] NSWCA 187; 69 NSWLR 558 at [163], [185]. A constraint in those terms would prevent the fixing of a period of notice for an extraneous purpose or one which could not on any view be justified as reasonable having regard to the purpose for which such a notice is given. That purpose, described generally, is to enable the parties to end their existing relationship and have a reasonable time to obtain either a substitute employee or other employment: see Birrell v Australian National Airlines Commission (1984) 5 FCR 447 at 458 (Gray J); and, in relation to a distributorship agreement, Crawford Fitting Co v Sydney Valve & Fittings Pty Ltd (1988) 14 NSWLR 438 at 448 (McHugh JA). In my view the power in cl 14.1(a) is to be read subject to such a constraint. The existence of that constraint substantially answers this argument of the appellant. It remains necessary, however, to address the language of the clause to see whether it is to be read as permitting the giving of a second or subsequent notice.
27The question is whether the right to terminate, once exercised, is to be regarded as exhausted. The valid exercise of the right conferred by cl 14.1(a) brings the agreement to an end, absent any subsequent consensual arrangement or conduct which compels a different outcome. Once the notice has been given the process of termination is engaged. At common law the general principle, which is subject to limited exceptions not relevant in the present context, is that a notice of termination, being a unilateral act that does not depend for its efficacy upon acceptance by the person to whom it is directed, cannot be unilaterally withdrawn: Riordan v War Office [1959] 1 WLR 1046 at 1054 (per Diplock J as his Lordship then was); on appeal [1961] 1 WLR 210; State of New South Wales v Paige [2002] NSWCA 235; 60 NSWLR 371 at [277], [283] (Spigelman CJ, Mason P and Giles JA relevantly agreeing). See also "Termination of Employment Contracts by Notice", GJ McCarry, (1986) 60 ALJ 78 at 82, 85. That principle applies equally to notices given by employers as to notices given by employees. To permit either party to give a second notice would in substance be to permit a party to withdraw an earlier notice by giving a later one.
28Upon the giving of a valid notice under cl 14.1(a) the introductory words to paragraph (b) ("If paragraph (a) applies") are satisfied. In that event, as between the appellant and respondent, rights and obligations are created or confirmed as continuing by cl 14.1(b). Whilst the words of that paragraph could be read as applying distributively to any notice given under cl 14.1(a), in their terms they refer to "the" applicable notice period, suggesting that there is only one such period to which the provisions of that paragraph could apply.
29By cl 14.1(b)(i) and (iii) the respondent is required to remain available to provide his services to the appellant and to attend its offices for all or part of the "applicable notice period" or "period of notice under paragraph (a)". These provisions require the respondent to keep himself free for the whole of that period and not to take other employment. The period during which that obligation applies may be shortened by a payment in lieu of the unexpired portion of the notice period. In the absence of such a payment, the respondent must make himself available for the whole period. Clause 14.1(b)(iv) confers on the appellant the entitlement to make a payment in lieu of notice and on the respondent the corresponding right to receive such a payment or to be paid his remuneration during the notice period. To permit a second and shorter notice to be given by either party, would enable the appellant to modify, by subtracting from, its obligation to pay and the respondent's entitlement to receive payment. To allow that possibility would introduce uncertainty at the outset as to the period of notice and as to the amount of the payment to which the employee was entitled in lieu of notice.
30In my view the construction urged by the respondent gives effect to the language which the parties have used and takes account of their likely commercial purposes and objects. The parties have agreed that either may terminate the employment "at any time", using terminate to refer to the act or process of giving a written notice to the other. By giving a notice the parties engage the process of termination. That process gives rise to rights and obligations as between the parties.
31Once exercised the right to terminate by notice is exhausted notwithstanding that the agreement has not yet come to an end. A construction of cl 14.1 as engaged by the first valid notice of termination is consistent with the references to "the" period of notice which has engaged the operation of that paragraph. That construction does not introduce uncertainty or result in the subtraction of any rights conferred by cl 14.1(b)(ii) or (iv). It also is consistent with the general principle that a notice of termination once given cannot be withdrawn unilaterally.
32It is not necessary to construe the clause as permitting more than one notice so as to avoid a commercially unlikely outcome. If a notice is given in the first two years, it must be for "not less than" 12 months. That, however, does not permit one party to fix a notice period which is excessive by reference to notions of reasonableness and good faith in the exercise of that contractual power.
33For these reasons the primary judge correctly concluded that the appellant could not give a later notice which had the effect of shortening the respondent's notice period. None of the remaining issues arises because each depends for its success upon the appellant being entitled to give a later notice. I nevertheless will address each of those issues briefly.
