CBC17 v Minister for Immigration

The applicant, CBC17, arrived on Ashmore Island and sought a declaration that he was not an "unauthorised maritime arrival" under the *Migration Act 1958* (Cth). This application was made in light of the Federal Court's decision in *DBB16 v Minister for Immigration and Border Protection* [2018] FCAFC 178, which had implications for individuals arriving in similar circumstances. The applicant also sought to quash a decision made by the Immigration Assessment Authority. The matter was heard by Dowdy J in the Federal Court of Australia.

The central legal issue before the Court was whether the applicant, by virtue of his arrival on Ashmore Island, fell within the definition of an "unauthorised maritime arrival" as contemplated by the *Migration Act 1958* (Cth), particularly in light of the preceding authority of *DBB16*. This determination was critical to the applicant's ability to pursue further review or challenge the decision of the Immigration Assessment Authority.

Dowdy J reasoned that the applicant's circumstances were analogous to those considered in *DBB16*. The Court applied the principles established in that case, which held that individuals arriving on Ashmore Island in the manner described were not to be considered "unauthorised maritime arrivals" for the purposes of the Act. Consequently, the Court declared that the applicant was not an unauthorised maritime arrival and quashed the decision of the Immigration Assessment Authority.
