Deas v Issa (No 2)

The respondents, Issa, applied for costs following their successful appeal from the Administrative Appeals Tribunal (AAT) in the case of Deas v Issa (No 2). The primary dispute involved the interpretation and application of the Migration Act 1958 and related regulations, focusing on the authority of the Minister to cancel a visa under specific circumstances. The Federal Court was tasked with reviewing the AAT's decision and determining whether the respondents were entitled to costs despite the fact that the argument upon which their success was based was not raised before the Tribunal.

The legal issues before the court included whether the respondents were entitled to costs under the general law when their success in the appeal was derived from an argument that was not presented to the AAT. The court had to consider whether the principle that a successful party is entitled to costs unless there are compelling reasons not to award them applied in this context. Additionally, the court had to determine whether the argument that led to the respondents' success was fundamentally different from those presented to the AAT, which could impact the costs decision.

The court held that while the respondents were successful in their appeal, they were not entitled to costs because the argument upon which their success was based was not raised before the AAT. The court reasoned that it would be unjust to allow the respondents to recover costs for an argument that was not presented to the AAT, as it would potentially undermine the tribunal process. The court emphasised that while the principle of awarding costs to successful parties generally applied, it was not an absolute rule and could be subject to exceptions where it would be unjust to do so. Consequently, the court declined to make an order as to costs in favour of the respondents.
