Abuse of process and deed of release
65 As the High Court said in Tomlinson at 518 [24] (French CJ, Bell, Gageler and Keane JJ), the doctrine of abuse of process is informed in part by similar considerations of finality and fairness as those which underpin the doctrines of estoppel discussed above. The High Court went on to explain at 518-9 [24]-[26]:
24 … Applied to the assertion of rights or obligations, or to the raising of issues in successive proceedings, [the doctrine of abuse of process] overlaps with the doctrine of estoppel. Thus, the assertion of a right or obligation, or the raising of an issue of fact or law, in a subsequent proceeding can be simultaneously: (1) the subject of an estoppel which has resulted from a final judgment in an earlier proceeding; and (2) conduct which constitutes an abuse of process in the subsequent proceeding.
25 Abuse of process, which may be invoked in areas in which estoppels also apply, is inherently broader and more flexible than estoppel. Although insusceptible of a formulation which comprises closed categories, abuse of process is capable of application in any circumstances in which the use of a court's procedures would be unjustifiably oppressive to a party or would bring the administration of justice into disrepute. It can for that reason be available to relieve against injustice to a party or impairment to the system of administration of justice which might otherwise be occasioned in circumstances where a party to a subsequent proceeding is not bound by an estoppel.
26 Accordingly, it has been recognised that making a claim or raising an issue which was made or raised and determined in an earlier proceeding, or which ought reasonably to have been made or raised for determination in that earlier proceeding, can constitute an abuse of process even where the earlier proceeding might not have given rise to an estoppel.
(Footnotes omitted.)
66 In addition to the matters relied upon to support the estoppel claims, the respondent also relied upon the terms of the deed of release in the context of the submissions made in reliance on the doctrine of abuse of process.
67 The respondent contended that it was "unthinkable" that the parties would agree that the applicant would be entitled to a settlement sum of $65,000 yet still be entitled to bring the same claim relating to superannuation, or slightly different claims, afresh.
68 The following observations are made in relation to the deed of release.
69 First, it is not clear what the exclusion for claims "relating to the … Superannuation Guarantee (Administration) Act 1992" was intended to cover. That Act does not impose any obligation on employers to pay superannuation and confers no right on an employee to the payment of superannuation by an employer. As the High Court said in Roy Morgan Research Pty Ltd v Commissioner of Taxation [2011] HCA 35; (2011) 244 CLR 97 at [3] (French CJ, Gummow, Hayne, Crennan, Kiefel and Bell JJ):
Broadly speaking, the effect of the legislation under challenge is that if, as specified in the [Superannuation Guarantee (Administration) Act 1992 (Cth)], an employer fails to provide to all employees a prescribed minimum level of superannuation then any shortfall represented by failure to meet that minimum level in full, becomes the [superannuation guarantee charge (Charge)]. This impost is levied on the employer by the [Superannuation Guarantee Charge Act 1992 (Cth)]. The amount of the Charge is a debt due to the Commonwealth and payable to the respondent, the Commissioner of Taxation: Taxation Administration Act 1953 (Cth), Sched 1, s 255-5. The Charge includes a component for interest and an administration cost. The result is to supply an incentive to employers to make contributions to superannuation for their employees without incurring a liability to the Commissioner for the Charge.
70 To the extent that the release was excluding any rights the Commissioner of Taxation had against the employer, that was not a matter that could have been covered by the deed of release in the first place. Furthermore, by the time the deed of release had been executed, the respondent had made the superannuation contribution amounts sought by the applicant. Given the nature of the case as pleaded in the Federal Circuit Court, it is not clear what rights the applicant was seeking to retain which related to the Superannuation Guarantee (Administration) Act 1992 (Cth). It seems to the Court that the exclusion relating to the Act does not assist either party in the present proceedings.
71 Secondly, the applicant contends that the wide words of the deed of release must be read down relying upon the equitable principle that a release imports a knowledge in the releasor of what he releases: Grant v John Grant & Sons Pty Ltd (1954) 91 CLR 112 at 129 (Dixon CJ, Fullagar, Kitto and Taylor JJ). The respondent relies upon the exception to that principle "unless upon a particular and solemn composition for peace persons expressly agree to release uncertain demands: Grant at 129 (Dixon CJ, Fullagar, Kitto and Taylor JJ). It was contended by the respondent that the deed of release was entered into in circumstances where the relationship between the parties had come to an end and should be construed as bringing to an end all claims relating to that relationship.
72 As the plurality said in Grant at 129-30 (Dixon CJ, Fullagar, Kitto and Taylor JJ):
From the authorities which have already been cited it will be seen that equity proceeded upon the principle that a releasee must not use the general words of a release as a means of escaping the fulfilment of obligations falling outside the true purpose of the transaction as ascertained from the nature of the instrument and the surrounding circumstances including the state of knowledge of the respective parties concerning the existence, character and extent of the liability in question and the actual intention of the releasor.
73 The terms of the deed of release ought to be construed in the context of the recitals and the terms of the deed as a whole. The recitals specifically refer to the Federal Circuit Court proceedings and the claims made in those proceedings. The amount paid under the deed was said to be on account of penalties. The only penalty that could be payable was for breach of the Fair Work Act claimed in those proceedings. As explained above, it is difficult to understand how the breach of that Act pleaded in the Federal Circuit Court proceedings could relate to superannuation.
74 The only evidence before the Court on this application of the intention of the applicant was a hearsay affidavit of his legal representative testifying that the applicant had said that he had no intention to release a claim for loss of opportunity based on the late payment of superannuation and that, at the time of executing the release, he was not aware he had such a claim. The state of the applicant's knowledge and intention would need to be tested at trial.
75 Thirdly, the Court raised with the parties the issue of whether the deed of release was capable of effecting a release of a claim based on a breach of an award given force by the Fair Work Act in light of the principles set out by the Full Court in Wardman v Macquarie Bank Ltd [2023] FCAFC 13 at [215] (Wheelahan J, Bromberg J agreeing at [3], Snaden J agreeing at [287]). The extent to which the principles in Wardman are applicable in the present case is a matter that would need to be resolved at trial.
76 The issue of abuse of process in the present case appears to the Court to turn at least in part on the reasonableness of the applicant's conduct in not raising in the Federal Circuit Court proceedings the issue of late payment of superannuation and its effect on his opportunity to make an insurance claim. In the present case, the Court is not satisfied that the applicant has no reasonable prospect of prosecuting his claim by reason of the doctrine of abuse of process.
