MIMA v Rajamanikkam and Anor S122/2001

The High Court of Australia considered the appeal of the Minister for Immigration and Multicultural Affairs (MIMA) against the decision of the Federal Court of Australia in favour of Mr. Rajamanikkam and another applicant. The dispute concerned the validity of decisions made by the Minister to refuse to grant protection visas to the applicants, who were citizens of Sri Lanka. The applicants had arrived in Australia by boat and claimed asylum, alleging they feared persecution in their home country.

The central legal issue before the High Court was whether the Minister's decisions to refuse the protection visas were vitiated by a failure to provide the applicants with procedural fairness. Specifically, the court had to determine if the Minister was obliged to inform the applicants of adverse information that was to be relied upon in assessing their claims, and to provide them with an opportunity to respond to that information, before making a decision. This question arose in the context of the Minister's assessment of whether the applicants met the criteria for a protection visa under the *Migration Act 1958* (Cth).

The High Court, by majority, held that the Minister's decisions were invalid due to a breach of the duty to afford procedural fairness. The majority reasoned that the Minister's assessment involved the consideration of adverse information that was not disclosed to the applicants, and that this information was material to the outcome of their visa applications. The court affirmed the principle that where a decision-maker proposes to rely on adverse information that has not been disclosed to the affected party, procedural fairness generally requires that the party be given notice of the information and an opportunity to comment on it. This principle applies even in the context of administrative decision-making under the *Migration Act*, unless Parliament has clearly evinced an intention to exclude it.

Consequently, the High Court dismissed the Minister's appeal and affirmed the orders of the Federal Court. The decisions to refuse the protection visas were set aside, and the matter was remitted to the Minister for reconsideration according to law.
