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

This matter concerned an application for Australian citizenship by descent. The applicant, born outside of Australia, sought citizenship on the basis that one of his parents was an Australian citizen at the time of his birth. The dispute arose from the interpretation of the term "parent" within the relevant legislation, specifically whether it encompassed a parent by legal adoption.

The Administrative Appeals Tribunal was required to determine whether a legal adoption, recognised outside of Australia, could satisfy the criteria for citizenship by descent under the Act. The central legal issue was the meaning of "parent" in the context of section 16(2)(a) of the Act, and whether this definition extended to a parent through legal adoption, even if the adoption did not comply with Australian law or occurred before the ratification of the Hague Convention.

The Tribunal reasoned that the ordinary meaning of "parent" is not limited to a biological parent and can include an adopted parent. It found that a legal adoption, even if not conducted under Australian law, could establish a parent-child relationship for the purposes of citizenship conferral, treating the child as if born to the adoptive parent. Consequently, the Tribunal set aside the delegate's decision to refuse citizenship and remitted the matter for reconsideration, directing that the applicant was eligible for citizenship by descent as he had an Australian citizen parent at the time of his birth.
