Background
5 I have considered the respondent's submissions of 10 September 2010 and the applicant's submissions in response of 20 September (two parts) and 27 September 2010 as well as his submissions on whether the issues raised have been previously determined in other proceedings of 27 August 2010. There is some overlaps in the sets of submissions. The respondent has, in its submissions, referred to a number of other decisions in proceedings between the applicant and the respondent in the FCA, the SCSA, the DCSA and the WCT and the WCAT, as well as the AIRC (all of which are a matter of record). It has also referred to the pleadings in certain of those proceedings to identify the issues raised in them. I have not had regard to those pleadings.
6 The submissions indicate that a number of facts are not in issue, or can be assumed in favour of the applicant for the purposes of these reasons.
7 The applicant was employed by the respondent until March 1994. As the respondent was an exempt employer under the WRC Act, it was liable to pay compensation to the applicant under that Act if he suffered a compensable disability arising out of or in the course of his employment according to and subject to the terms of the WRC Act. He asserts that the respondent had "a statutory and (sic) obligation not to act fraudulently or unconscionably" to deceive the applicant or to avoid liabilities or to obtain benefits or other entitlements under the WRC Act to which it was not entitled.
8 The applicant alleges that in May 1988 he injured his right middle finger at work. He also alleges that in May 1989 he injured his back and left leg at work. Then on 16 August 1991, he alleges, he suffered a compensable "psychological injury/mental breakdown". He further alleges that a medical practitioner on 28 April 1993 informed the respondent that, as a result of that condition, the applicant would not be able to return to work. On 16 March 1994, the respondent wrote to the applicant terminating his employment on the ground that he continued to be unfit for his normal duties; a statement of termination specified 31 March 1994 as the termination date. I shall treat the termination date as 16 March 1994. Nothing turns on the few weeks' difference for the purposes of this application. The injuries other than the May 1988 injury are disputed by the respondent. The Heads of Agreement also refers to an eye injury in December 1986.
9 In December 1997, the applicant suffered a heart attack, and subsequently had open heart surgery. On 7 April and 7 June 1998 he claimed compensation from the respondent for aggravation of his pre-existing coronary heart disease and depression. Although it is not expressly pleaded, the applicant also apparently had ongoing disputes with the respondent about his entitlements to compensation and in other respects including a claim for damages or loss for unfair dismissal arising from his termination.
10 The respondent's submissions accept that the applicant was employed by it when he suffered a finger injury in May 1988 and a back injury in May 1989. The applicant received compensation for the finger injury, including ultimately a lump sum. It says that after an incident on 9 May 1989, the applicant complained of cramps in his left leg relating to the back injury, resulting in short periods of incapacity. Those claims were, it says, resolved by payment of the claimed compensation by 2 September 1991. The payment then did not include any redemption or final lump sum payment. A claim for damages on the basis that the back injury was caused by the respondent's negligence was then outstanding, but in July 1992 that claim in the DCSA was dismissed: Kowalski v Mitsubishi Motors Australia Ltd (unreported, District Court of South Australia, Lee J, 3 July 1992). Subsequently, the applicant made further claims for compensation in respect of the back injury. They were unsuccessful: Mitsubishi Motors Australia Ltd v Harbord and Kowalski (unreported, Supreme Court of South Australia, Debelle J, 21 November 1996). The SCSA ultimately held that the DCSA decision resulted in an issue estoppel adverse to the applicant on the question whether the applicant had in fact suffered that injury as he alleged: Mitsubishi Motors Australia Ltd v Harbord and Kowalski (1997) 69 SASR 75.
11 The applicant did not return to work again after 16 August 1991. An issue arose on that day about his entitlement to certain claimed payments for absences. He claimed compensation for incapacity for psychological distress arising from that issue. That claim was dismissed by a Review Officer under the WRC Act on 9 March 1994, and that decision was upheld by the WCAT and the SCSA: Kazimir Kowalski v Mitsubishi Motors Automotive Ltd [1995] SAWCAT 63 and Mitsubishi Motors Australia v Kowalski (unreported, Supreme Court of South Australia, Cox, Perry and Williams JJ, 6 February 1996). Subsequently, claims for further compensation in respect of the stress injury under the WRC Act were unsuccessful because the earlier decision of the Review Officer and on appeal had resolved the issue adversely to the applicant.
12 Following the termination of the applicant's employment on 16 March 1994, the applicant challenged that termination and alternatively sought reinstatement. The AIRC ultimately by the Full Commission, refused those claims. In 1997, the applicant sought from the FCA an extension of time in which to bring unfair dismissal proceedings against the respondent. That application was unsuccessful because, having regard to the termination date, the FCA had no power to make the order sought: Kowalski v Mitsubishi Motors Australia Limited (1998) 88 FCR 55.
13 Then, in the sequence of events came the mediation of outstanding issues and claims on 26 October 1998 leading to the Heads of Agreement the following day.
14 The Heads of Agreement record that a payment of $200,000 was to be made by the respondent to the applicant with a denial of liability and in full and final settlement of any eye injury in December 1986, the finger injury in May 1988, the back and left leg injury in May 1989, the alleged stress or mental breakdown in August 1991 and the heart attack in December 1997. As recorded by Bleby J in Mitsubishi Motors Australia Ltd v Kowalski [2005] SASC 154 at [145]-[147], at the time of the Heads of Agreement the respondent denied any outstanding liability under the WRC Act to the applicant in relation to his claimed work-related injuries save for small amounts for the eye and finger injuries and it had significant claims for costs against the applicant ordered to be paid by the applicant to it.
15 The applicant duly received the $200,000.
16 However, that did not bring the applicant's claims against the respondent to an end.
17 As noted, following the applicant's heart attack in 1997 and alleged consequential depression, he sought compensation from the respondent in respect of it. Proceedings for compensation under the WRC Act had been instituted. They were dismissed by consent in November 1998 following, and in accordance with, the Heads of Agreement and payment to the applicant of $200,000.
18 In November 1999, the applicant applied to the WCT to have the consent orders referred to in [17] set aside (and subsequently also for orders that he could further pursue compensation claims in respect of other alleged compensable injuries), on the grounds that the mediation leading to the Heads of Agreement was not conducted in good faith and so was affected by fraud or unconscionable conduct, and in any event that the settlement by the Heads of Agreement could not resolve or exclude any liability to pay compensation under the WRC Act. He also claimed that the consent orders of November 1998 were void because the respondent had not complied with r 3(4) of the WCT Rules or had not registered the Heads of Agreement or had not complied with s 119 of the WRC Act.
19 On 14 August 2001 that application was dismissed. Each of the applicant's claims was rejected: Kowalski v Mitsubishi Motors Australia [2001] SAWCT 93. An appeal to the WCAT was dismissed: Kowalski v Mitsubishi Motors Australia [2002] SAWCT 76. As it is relevant to a matter discussed below, I note also that on 2 January 2000, the preliminary question as to whether the WCT had jurisdiction to hear the application was determined and it was decided that notwithstanding the inquiry involving consideration of the Heads of Agreement which included terms not strictly involving workers compensation, it had jurisdiction: Kowalski v Mitsubishi Motors Australia Ltd [2000] SAWCT 2. Mitsubishi appealed from this preliminary determination. Its appeal was dismissed by the WCAT on 15 August 2000: Mitsubishi Motors Australia Ltd v Kowalski [2000] SAWCT 123. The application to set aside the consent orders was then heard and on 14 August 2001 it was dismissed.
20 Various proceedings were then instituted in this Court asserting the applicant's employment had not terminated in March 1994 (the statement of claim now asserts that it was terminated in March 1994), claiming wages thereafter, and for compensation in respect of some of the alleged injuries or conditions. Those proceedings were dismissed, and in the one instance of an appeal, the appeal to the Full Court was unsuccessful: Kowalski v Mitsubishi Motors Australia Ltd Staff Superannuation Fund Pty Ltd [2002] FCA 1153 and Kowalski v Trustee, Mitsubishi Motors Australia Limited Staff Superannuation Fund [2003] FCAFC 18. They were dismissed because the applicant was bound by the terms of the Heads of Agreement or was abusing the processes of the Court by seeking to re-agitate matters already determined adversely to him.
21 On 19 April 2005, the SASC declared the applicant a vexatious litigant: Mitsubishi Motors Australia Ltd v Kowalski [2005] SASC 154. The decision was upheld on appeal by the Full Court of the SASC: Kowalski v Mitsubishi Motors Australia Ltd [2005] SASC 433. In essence, the conclusions and the reasons for decision of the WCT referred to at [18] and [19] above were the reasons why the SASC made that order.
22 The applicant then returned to the FCA. One application sought to invoke the Trade Practices Act 1975 (Cth) (the TP Act) in a non-specific way, making allegations of fraud, breach of trust, misrepresentation and non-compliance with statutory requirements in relation to the Heads of Agreement. The other was an appeal from the Administrative Appeals Tribunal about its finding concerning the asserted responsibility of the respondent to the Health Insurance Commission or Medicare under the Health and Other Services (Compensation) Act 1995 (Cth) (the HOSC Act), because the Heads of Agreement included resolution of his compensation claims or some of them, and also invoking in a non-specific way the TP Act apparently to enliven the jurisdiction of the FCA. Those proceedings were each summarily dismissed: Kowalski v Mitsubishi Motors Australia Ltd [2009] FCA 991 and Kowalski v Chief Executive Officer of Medicare Australia [2010] FCA 413.
