Sinnathamby v Minister for Immigration and Border Protection

This matter concerned an application for Australian citizenship by Mr Sinnathamby, which was refused by the Minister for Immigration and Border Protection. The dispute centred on whether Mr Sinnathamby had satisfied the threshold requirement of proving his identity to the satisfaction of the Minister, as mandated by section 24(3) of the *Australian Citizenship Act 2007* (Cth). The Administrative Appeals Tribunal was required to determine if the evidence presented by Mr Sinnathamby was sufficient to meet this statutory obligation.

The primary legal issues before the Tribunal were whether Mr Sinnathamby had provided a "bogus document" in support of his application, and whether inconsistencies in the information he provided to the Department raised sufficient concerns about his identity and truthfulness. Specifically, the Tribunal had to consider the authenticity and integrity of a Sri Lankan identity card provided by Mr Sinnathamby, which contained an inconsistency regarding his occupation in 2003. The Tribunal also had to assess whether any alleged tampering with the identity card, whether by Mr Sinnathamby or another party, adversely reflected on his character or his ability to satisfy the identity requirements.

The Tribunal applied the principles of "reasonable satisfaction" as articulated in *Briginshaw v Briginshaw* and subsequent cases, requiring an actual persuasion of the facts rather than a mere mechanical comparison of probabilities. It found that the Sri Lankan identity card, even if repaired by Mr Sinnathamby's mother, was presented as a primary identity document for a serious purpose. The Tribunal did not accept the analogy that Mr Sinnathamby was like a person unwittingly tendering a counterfeit banknote, given the nature of the document and its purpose. Despite the Minister not contending that Mr Sinnathamby was an imposter, the Tribunal concluded that, based on the information furnished, he had not met the requirements to satisfy the Act as to his identity.

Consequently, the Tribunal affirmed the decision under review, meaning Mr Sinnathamby's application for citizenship was not approved on the basis of the evidence presented.
