CQO16 v Minister for Immigration

The applicant sought judicial review of a decision by the Migration Review Tribunal, which had set aside an earlier decision to refuse a Protection (Class XA) visa and substituted a refusal for a Protection (Class XD) visa. The applicant, initially unrepresented, later obtained legal representation. The Minister for Immigration was the respondent.

The court was required to determine whether the Tribunal's decision involved jurisdictional error. Specifically, the applicant contended that the Tribunal's reasoning was illogical, irrational, or legally unreasonable, and that it failed to give proper, genuine, or realistic consideration to a significant matter. The court also considered the principles governing when a claim, not explicitly articulated by an applicant, is required to be considered by the Tribunal.

The court referred to established principles from cases such as *Minister for Immigration and Border Protection v Sabharwal* and *AYY17 v Minister for Immigration and Border Protection*. These principles clarify that jurisdictional error can arise from illogical or irrational decision-making, or a failure to consider significant matters genuinely. A decision or finding is not legally unreasonable if a reasonable decision-maker could reach it on the same material. Regarding claims, the Tribunal is only obliged to consider those that are either substantially and clearly argued based on established facts, or that clearly emerge from the materials. The court noted that a claim emerging from materials is not sufficient; it must be based on established facts and not be made lightly. Furthermore, when assessing whether an unarticulated claim has clearly emerged, a court may be more inclined to favour an unrepresented party, and the assessment must consider how claims have been presented over time.
