The nature and history of the proceeding
1 On 16 February 2012, the Federal Magistrates Court of Australia ordered the issue of writs having the effect of quashing a decision of the second respondent to this appeal, the Refugee Review Tribunal ("the Tribunal") and directing the Tribunal to hear and determine that application according to law. Those orders were made in an application to the Federal Magistrates Court by the first respondent to this appeal. The orders and reasons for judgment of the learned federal magistrate are published as MZYNN v Minister for Immigration & Anor [2012] FMCA 96. The Tribunal's decision was to affirm a decision of a delegate of the appellant, the Minister for Immigration and Citizenship ("the Minister"), to refuse to grant to the first respondent a protection visa, pursuant to the Migration Act 1958 (Cth) ("the Migration Act").
2 The federal magistrate found that the Tribunal's decision was affected by jurisdictional error in two respects. First, her Honour found that delay on the part of the Tribunal in producing its decision and reasons for decision may have impaired the Tribunal's assessment of the credibility of the first respondent in respect of one aspect of his claims, and that the Tribunal therefore denied the first respondent a fair hearing. The first respondent claimed to have been attacked by members or supporters of a political party called the All People's Congress ("the APC"), who hit him with the blunt edge of a machete blade, causing injury, but then desisted from attacking him because they believed they had killed him. The Tribunal disbelieved this claim, although it had made a general finding on credibility that was favourable to the first respondent. The second jurisdictional error was the failure of the Tribunal to identify in its reasons how a particular social group of which the first respondent claimed to be a member should be defined. The Minister has appealed from that judgment, contending that the federal magistrate erred in reaching both conclusions.
3 At the hearing of this appeal, counsel for the first respondent sought and was granted leave to file a notice of contention dated 10 August 2012. By that notice, the first respondent contended that the judgment of the Federal Magistrates Court should be affirmed on a ground on which the federal magistrate had not relied. That ground was that, in disbelieving the first respondent's claim about the machete attack, the Tribunal made a decision that no reasonable person could have made. This contention had been raised in the application to the Federal Magistrates Court, but the federal magistrate had not found it necessary to deal with the contention, because she had found in favour of the first respondent on two other grounds.
4 By s 36 of the Migration Act, there is a class of visas to be known as protection visas. A criterion for a protection visa is that the person applying for it be a non-citizen in Australia to whom the Minister is satisfied Australia has protection obligations under the Refugees Convention as amended by the Refugees Protocol. The terms "Refugees Convention" and "Refugees Protocol" are defined in s 5(1) of the Migration Act to mean respectively the Convention relating to the Status of Refugees done at Geneva on 28 July 1951 and the Protocol relating to the Status of Refugees done at New York on 31 January 1967. It is convenient to call these two instruments, taken together, the "Convention". For present purposes, it is sufficient to note that, pursuant to the Convention, Australia has protection obligations to a person who:
owing to well-founded fear of being persecuted for reasons of race, religion, nationality, membership of a particular social group or political opinion, is outside the country of his nationality and is unable or, owing to such fear, is unwilling to avail himself of the protection of that country
5 The first respondent is a citizen of Sierra Leone. On 29 November 2008, he arrived in Australia as part of the team representing Sierra Leone in soccer, competing for the Homeless World Cup. On 23 December 2008, he applied for a protection visa. On 18 December 2009, a delegate of the Minister decided to refuse the application. The first respondent applied to the Tribunal for review of the decision of the Minister's delegate. On 9 February 2010, the Tribunal conducted a hearing, at which the first respondent gave evidence and presented arguments, assisted by a migration agent and an interpreter. On 20 May 2010, the Tribunal wrote to the first respondent, pursuant to s 424A of the Migration Act, inviting him to respond to information it considered might be the reason, or part of the reason, for affirming the delegate's decision. The first respondent's migration agent responded on his behalf on 31 May 2010.
6 The first respondent provided a substantial amount of written material to the Tribunal, both before and after the Tribunal's hearing, including material supplied in June and July 2010.
7 The Tribunal's decision, and written reasons for decision, are dated 25 May 2011 and were forwarded to the first respondent and his migration agent by letters dated 26 May 2011.
