NBIO v MIMA & Anor

NBIO (the applicant) sought judicial review of a decision by the Minister for Immigration and Multicultural Affairs (MIMA) and the second respondent, the Refugee Review Tribunal (RRT), to refuse to grant the applicant a protection visa. The applicant, who was of Sri Lankan origin, claimed to have been persecuted in Sri Lanka due to his involvement with the Liberation Tigers of Tamil Eelam (LTTE). The RRT had affirmed the delegate's decision to refuse the visa, finding that the applicant had not established a well-founded fear of persecution. The matter came before the High Court of Australia on appeal from the Full Federal Court.

The central legal issue before the High Court was whether the RRT had erred in law by failing to consider, or adequately consider, the applicant's claims regarding his past membership and involvement with the LTTE when assessing his fear of persecution. Specifically, the court considered whether the RRT's approach to the applicant's past association with the LTTE was consistent with the requirements of the *Migration Act 1958* (Cth) and the *Refugee Convention*. The applicant argued that his past membership, even if not constituting a current threat, could still be a basis for a well-founded fear of persecution by Sri Lankan authorities.

Gummow and Heydon JJ held that the RRT had made an error of law. Their Honours explained that the RRT's reasoning, which focused on the applicant's current lack of involvement with the LTTE and the absence of direct threats against him, failed to properly engage with the possibility that past membership or association could itself be a reason for persecution. The court reiterated the principle that a person's past political opinions or affiliations can form the basis of a well-founded fear of persecution, even if they no longer hold those opinions or are no longer actively involved. The RRT was required to assess whether the Sri Lankan authorities would perceive the applicant as a member or supporter of the LTTE and, if so, whether that perception would lead to persecution.

The High Court allowed the appeal, setting aside the decision of the Full Federal Court and remitting the matter to the Refugee Review Tribunal for redetermination according to law.
