Dua16 v Minister for Immigration & Anor and CHK16 v Minister for Immigration

In *Dua16 v Minister for Immigration & Anor* and *CHK16 v Minister for Immigration*, Riethmuller J of the Federal Court of Australia considered applications for judicial review of decisions made by the Immigration Assessment Authority (IAA). The applicants sought to challenge the IAA's refusal to grant them protection visas, alleging that the IAA had been misled by fraudulent conduct on the part of their migration agent. The agent had submitted substantially the same documentation and arguments in approximately 40 unrelated cases, including those of the applicants, which contained factual assertions and circumstances pertaining to a different individual.

The central legal issue before the Court was whether the IAA’s decisions were vitiated by the fraudulent conduct of the applicants' agent. Specifically, the Court had to determine if the use of identical submissions, which were not tailored to the individual circumstances of each applicant but rather to those of another person, amounted to a fraud upon the IAA that rendered its decision-making process unfair or unlawful. This involved considering whether the IAA was presented with material that was fundamentally misleading and whether this impacted the validity of its findings.

Riethmuller J found that the migration agent's conduct constituted a fraud upon the IAA. The Court reasoned that the IAA was presented with submissions that were not genuine to the applicants' own circumstances but were instead fabricated to appear as such, based on the facts of another case. This deliberate misrepresentation of material facts meant that the IAA did not engage with the actual circumstances of the applicants, thereby undermining the integrity of the decision-making process. Consequently, the Court concluded that the IAA’s decisions were affected by this fraud and were therefore unlawful. The applications for judicial review were allowed.
