Mensah and Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs (Citizenship)

This matter concerned an application for review of a decision to revoke the applicant's Australian citizenship. The applicant had been convicted of multiple offences, including migration offences under the *Migration Act 1958* (Cth) and a citizenship offence under the *Australian Citizenship Act 2007* (Cth). He was also convicted of aggravated sexual assault of a minor. The Minister's decision to revoke citizenship was based on the applicant's criminal convictions and the belief that it was contrary to public interest for him to remain an Australian citizen. The Administrative Appeals Tribunal was required to determine whether the decision to revoke citizenship was justified.

The primary legal issues before the Tribunal were whether the applicant's conduct was contrary to the public interest, thereby providing grounds for revocation of his citizenship under the *Australian Citizenship Act 2007*, and whether the Minister's discretion not to revoke citizenship should have been exercised in his favour. The Tribunal had to consider the applicant's extensive history of dishonesty and criminal behaviour, including false statements made in visa and citizenship applications, his previous adverse migration history, and his serious criminal convictions.

The Tribunal reasoned that the applicant's repeated dishonesty and the gravity of his criminal convictions, particularly the offence against a child, demonstrated a clear disregard for Australian law and values. It found that the applicant had engaged in a pattern of deception to gain entry and permanent residency in Australia, and subsequently citizenship, by failing to disclose crucial information about his identity, previous marriages, children, and migration history. The Tribunal concluded that such conduct was fundamentally contrary to the public interest and that there were no mitigating circumstances that would warrant the exercise of discretion to allow him to retain his Australian citizenship.

The Tribunal affirmed the decision of the Minister to revoke the applicant's Australian citizenship.
