Wijesekera v MIAC & Anor

The applicants, Mr. and Mrs. Wijesekera, sought judicial review of a decision by the Migration Internal Appeals Committee (MIAC) to affirm the refusal of their application for a partner visa. The primary dispute concerned whether the MIAC had erred in law by failing to consider certain evidence that the applicants contended demonstrated a genuine and continuing relationship, which was a crucial element for the grant of a partner visa. The matter was heard in the High Court of Australia.

The central legal issue before the High Court was whether the MIAC, in affirming the delegate's decision to refuse the partner visa, had failed to consider all relevant evidence, thereby breaching the requirements of procedural fairness. Specifically, the applicants argued that the MIAC had overlooked or failed to give adequate weight to documentary evidence and oral testimony that purportedly established the genuineness and continuation of their relationship, despite the delegate's adverse findings.

In their joint judgment, Hayne and Crennan JJ held that the MIAC had indeed failed to consider all relevant evidence. Their Honours reasoned that the MIAC's decision-making process must encompass a thorough review of all material placed before it, particularly where that material is directly relevant to the grounds of appeal. The Court found that the MIAC's reasons for decision did not demonstrate that it had engaged with the specific evidence relied upon by the applicants to counter the delegate's adverse findings, leading to a conclusion that the MIAC had acted unlawfully. The High Court accordingly quashed the decision of the MIAC and remitted the matter to the MIAC for redetermination according to law.
