Miller v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs & Anor

The High Court of Australia considered the case of *Miller v Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs & Anor*. The dispute concerned the lawfulness of a decision by the Minister to refuse to grant the applicant a visa. The applicant, Mr. Miller, sought judicial review of this decision.

The central legal issue before the High Court was whether the Minister's delegate had failed to consider relevant considerations and had taken into account irrelevant considerations when making the decision to refuse the visa. Specifically, the court had to determine if the delegate's assessment of the applicant's character, which was a crucial factor in the visa refusal, was vitiated by errors of law.

The High Court found that the delegate had indeed failed to consider relevant considerations and had taken into account irrelevant considerations. The delegate's assessment of Mr. Miller's character was based on a misinterpretation of certain evidence and an overemphasis on unsubstantiated allegations, while failing to give due weight to other pertinent information. The court reiterated the principle that a decision-maker must genuinely consider all relevant material placed before them and must not be influenced by irrelevant material. The delegate's failure to properly engage with the evidence amounted to an error of law.

The High Court ordered that the appeal be allowed, the decision of the Federal Court be set aside, and the matter be remitted to the Federal Court for determination of the appropriate relief.
