Madafferi, Ex parte Re Duncan & Anor, Madafferi v MIMA

This matter concerned an application for judicial review of a decision by the Minister for Immigration and Multicultural Affairs (MIMA) to refuse to grant a visa to Mr Madafferi. The applicants, Mr Madafferi and two others, sought to challenge the Minister's decision in the High Court of Australia.

The primary legal issue before the High Court was whether the Minister's decision to refuse the visa was vitiated by an error of law, specifically concerning the proper construction and application of s 501(1) of the *Migration Act 1958* (Cth). This section empowers the Minister to refuse a visa if the applicant does not pass the character test. The applicants contended that the Minister had failed to properly consider relevant information and had acted on irrelevant considerations when assessing Mr Madafferi's character.

The High Court, comprising McHugh and Hayne JJ, examined the scope of the Minister's discretion under s 501(1) and the principles of administrative law governing the exercise of such discretion. Their Honours considered the nature of the "character test" and the evidence that could be taken into account. The Court ultimately found that the Minister's decision had been affected by an error of law, as the Minister had failed to give adequate weight to certain exculpatory material presented by Mr Madafferi, thereby misconstruing the nature of the character assessment required by the Act.

The Court made orders quashing the Minister's decision and remitting the matter to the Minister for reconsideration according to law.
