PROCEDURAL BACKGROUND
13 Mr Wong is a national of China. He first entered Australia on 22 August 1999. At that time he was the holder of a Subclass 676 Visitor (Short Stay) Visa, issued in Hong Kong. On November 1999 he was granted a Subclass 560 Student Visa, which was valid until 5 January 2001. On 15 December 2000, Mr Wong lodged an application for the grant of a further Subclass 560 Student Visa. On 25 January 2001, he was granted a Bridging Visa A while that application was under consideration.
14 On 22 January 2002, the Minister decided, as contemplated by s 501(3) of the Act, that he reasonably suspected that Mr Wong did not pass the character test and that he was satisfied that a refusal of the visa applied for was in the national interest. Accordingly, the Minister decided to exercise his discretion to refuse the visa for which Mr Wong applied. He therefore refused the visa ('the Grant Refusal Decision').
15 On 25 January 2002 a delegate of the Minister wrote to Mr Wong saying, relevantly:
'On 22 January 2002 [the Minister]… refused to grant you a subclass 560 Student Visa… A copy of the relevant legislative provisions and the decision record concerning the refusal to grant you a visa are attached for your information. Please note that Attachments C1-10 of the Decision Record document were not released as they are protected under s 503A of the Act.'
16 On 7 February 2002, Mr Wong was handed the letter dated 25 January 2002 notifying him of the Grant Refusal Decision and enclosing a copy of relevant legislative provisions and of the document referred to in the letter as 'the Decision Record' ('the Decision Record'). The Decision Record was a document prepared within the Department of Immigration and Multicultural and Indigenous Affairs ('the Department') to enable the Minister to consider making a decision concerning Mr Wong's application for a student visa. Upon being handed the letter and its two enclosures, Mr Wong was taken into immigration detention, since, at that time he was an illegal non resident; his substantive student visa had expired on 5 January 2001 and his bridging visa expired upon the making of the Grant Refusal Decision.
17 On 15 February 2002, Mr Wong commenced a proceeding ('the First Proceeding') in the Federal Court of Australia under s 39B(1) of the Judiciary Act 1903 (Cth) ('the Judiciary Act') claiming relief in respect of the Grant Refusal Decision. On 6 August 2002, Tamberlin J ordered that the application in the First Proceeding be dismissed with costs. On 26 August 2002, Mr Wong appealed to the Full Court from those orders and, on 20 December 2002, the appeal was dismissed with costs. An application for special leave to appeal to the High Court from the orders of the Full Court is still pending the outcome of these proceedings.
18 Pursuant to the invitation contained in the letter of 25 January 2002, Mr Wong, through his solicitor, Mr Peter W.H. Leung, made representations to the Minister pursuant to s 501C of the Act, requesting the Minister to revoke the Grant Refusal Decision. However, on 28 May 2002, the Minister decided not to revoke the Grant Refusal Decision ('the Revocation Refusal Decision').
19 On 5 July 2002, Mr Wong instituted another proceeding ('the Second Proceeding') in the Federal Court pursuant to s 39B(1) of the Judiciary Act. By the Second Proceeding, Mr Wong claimed relief in respect of the Revocation Refusal Decision. On 6 November 2002, Wilcox J ordered that the application in the Second Proceeding be dismissed with costs. The first appeal before this Full Court is brought from the orders of Wilcox J by notice of appeal filed on 22 November 2002 ('Mr Wong's First Appeal').
20 On 18 February 2002, Mr Wong made a request under s 15 of the Freedom of Information Act 1982 (Cth) ('the FOI Act') for access to certain documents, including Attachments C1-10 referred to in the Decision Record. On 18 April 2002, an officer of the Department decided that access to Attachments C1-10 should be refused on the ground that they contained information that was protected by s 503A. On 17 May 2002, Mr Wong requested an internal review of the decision of the Departmental officer and on 15 July 2002 another officer of the Department exempted Attachments C1-10 from disclosure ('the Exemption Decision').
21 On 13 September 2002, Mr Wong applied to the Administrative Appeals Tribunal ('the AAT') for review of the Exemption Decision. On 14 August 2003 a Deputy President of the AAT resolved what he described as 'the preliminary issue in this matter'. The Deputy Present decided, inter alia, that s 503A(1) of the Act did not protect from disclosure documents supplied by the Chinese Ministry, on the ground that that body was not a 'gazetted agency' for the purposes of s 503A(9) of the Act.
22 On 4 September 2003, the Minister filed a notice of appeal to the Federal Court, purportedly under s 44 of the Administrative Appeals Tribunal Act 1975 (Cth) ('the AAT Act'), from the decision of the Deputy President of 14 August 2003. The Minister claimed orders setting aside that decision and remitting the matter to the Tribunal for further consideration.
23 Mr Wong challenged the competency of the Minister's purported appeal from the AAT on the ground that there was no decision of the AAT within the meaning s 44(1) of the AAT Act. On 6 February 2004, Lindgren J ordered that the application in that proceeding be dismissed as incompetent. There is no appeal from the order dismissing the appeal from the AAT as incompetent. However, the proceeding has some relevance as will appear later.
24 On 11 March 2002, Mr Wong applied to the High Court of Australia for constitutional writ relief in respect of the Grant Refusal Decision ('the Grant Refusal Proceeding'). On 10 July 2002, Mr Wong also applied to the High Court of Australia for constitutional writ relief in respect of the Revocation Refusal Decision ('the Revocation Refusal Proceeding). On 6 February 2003, Gaudron J ordered that further proceedings in both applications be remitted to the Federal Court.
25 On 12 August 2003, Mr Wong filed, with leave, what purported to be an application pursuant to s 39B(1) of the Judiciary Act in the remitted Grant Refusal Proceeding and an amended application pursuant to s 39B(1) of the Judiciary Act in the remitted Revocation Refusal Proceeding. On 16 October 2003, the Minister filed notices of motion in each of those proceedings seeking orders that the claims for relief, in so far as they were based on certain of the grounds set out in the application and amended application respectively, be dismissed pursuant to O 20 r 2(1)(c) of the Federal Court Rules. The Minister contended that claims for relief on the grounds specified were an abuse of the process of the Court. In the case of the Grant Refusal Proceeding, that contention was based on the result of the First Proceeding. In the case of the Revocation Refusal Proceeding the Minister's contention was based on the result of the Second Proceeding. In essence, the Minister contended that relief on the specified grounds was barred by the doctrines of res judicata, issue estoppel and Anshun estoppel.
26 The motions and the substantive claims in each of the Grant Refusal Proceeding and the Revocation Refusal Proceeding were heard together by Lindgren J. On 6 February 2004, his Honour concluded that the motions for summary dismissal would succeed in respect of certain grounds. However, his Honour then proceeded to deal with the balance of each proceeding in so far as it was based on grounds that did not give rise to a defence of res judicata or estoppel.
27 In relation to the Grant Refusal Proceeding, his Honour ordered that orders nisi in the nature of certiorari and of mandamus in relation to the Grant Refusal Decision be made but that the orders nisi be discharged and that Mr Wong pay the Minister's costs. His Honour ordered that the application in the Grant Refusal Proceeding be otherwise dismissed. Mr Wong now appeals to the Full Court from those orders ('Mr Wong's Second Appeal').
28 In the Revocation Refusal Proceeding, Lindgren J made an order absolute in the nature of certiorari, quashing the Revocation Refusal Decision and an order absolute in the nature of mandamus that the Minister perform the obligations imposed by s 501C(3) and s 501C(4) in relation to the Grant Refusal Decision. His Honour ordered the Minister to pay Mr Wong's costs and that the application in the Revocation Refusal Proceeding be otherwise dismissed. The Minister now appeals to the Full Court from those orders ('the Minister's Appeal').
29 On 8 April 2004, Lindgren J ordered ('the Stay Order') that the order absolute in the nature of mandamus in the Revocation Refusal Proceeding be stayed until the hearing and determination of the Minister's Appeal. On 30 April 2004, Mr Wong filed a notice of motion seeking, relevantly, leave to file that motion out of time, if leave be needed, and leave to appeal from the Stay Order.
