Onyema and Minister for Immigration and Border Protection (Citizenship)

This matter concerned an application for Australian citizenship by descent. The applicant, born outside of Australia, sought to establish that one of his parents was an Australian citizen at the time of his birth. The respondent was the Minister for Immigration and Border Protection.

The central legal issue before the Tribunal was to determine whether Mr Onyema was a "parent" of the applicant at the time of the applicant's birth, within the meaning of section 16(2)(a) of the relevant Act. This required an interpretation of the term "parent" in the context of citizenship by descent.

The Tribunal considered the ordinary meaning of "parent" and found it was not limited to a biological parent. It examined Mr Onyema's conduct before, at the time of, and after the applicant's birth, including his financial support of Ms Aigbiko and his stated intention to commence a family with her. The Tribunal was satisfied that Mr Onyema genuinely believed he was the applicant's father, had accepted responsibility for him since being informed of the pregnancy, and was the Australian parent at the time of birth. Consequently, the Tribunal set aside the delegate's decision to refuse the citizenship application and remitted the matter for reconsideration, directing that the applicant was eligible for citizenship.
