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

This matter concerned an appeal by Mr Ayoker against a decision by the Minister for Immigration, Citizenship, Migrant Services and Multicultural Affairs. The dispute centred on whether Mr Ayoker was the biological parent of Miss M, and consequently, whether Miss M could be considered the child of an Australian citizen at birth. The Administrative Appeals Tribunal (the Tribunal) heard the matter, with Mr Ayoker representing himself and his daughter, and the Minister represented by the Australian Government Solicitor.

The primary legal issue before the Tribunal was to determine whether Mr Ayoker had established a parent-child relationship with Miss M, notwithstanding the DNA evidence indicating he was not her biological father. This required the Tribunal to consider the definition of "child" in the context of citizenship law, particularly when biological parentage is disputed, and to assess the nature and extent of Mr Ayoker's commitment and involvement in Miss M's life.

The Tribunal reasoned that parentage is not solely a matter of biology but also encompasses "intense commitment to another, expressed by acknowledging that other person is one’s own and treating him or her as one’s own." Applying this principle, the Tribunal found that Mr Ayoker had demonstrated an intense commitment through his consistent financial and emotional support for Ms Aleng, both before and after Miss M's birth. This support included providing accommodation, covering medical expenses, and actively participating in decisions regarding Miss M's upbringing, such as choosing her name. The Tribunal also noted the significant factor of Mr Ayoker and Ms Aleng's committed relationship and marriage prior to Miss M's birth, and the widespread acceptance within their families and communities that Mr Ayoker was Miss M's father.

Based on these findings, the Tribunal concluded that Mr Ayoker had played a parental role in Miss M's life and that she should be considered his child for the purposes of citizenship law. The Tribunal therefore set aside the Minister's decision and remitted the matter for reconsideration.
