1412960 (Migration)

This matter concerned a decision made under Part 5 of the *Migration Act 1958* (Cth). The specific issue before the court was whether a particular decision was a "Part 5-reviewable decision" as defined by section 338(2) of the Act. The court was required to interpret the criteria set out in section 338(2) and relevant regulations, including Regulation 4.02(1A) and 4.02(1AA), to determine if the decision in question fell within the scope of reviewable decisions.

The court's reasoning focused on the statutory definition of a "Part 5-reviewable decision" and the meaning of "sponsored" and "nominated" as provided by the *Migration Regulations 1994* (Cth). It examined the conditions under which a decision to refuse to grant a visa is reviewable, particularly concerning the applicant's location in the migration zone, their immigration clearance status, and sponsorship requirements for certain temporary visas, such as the Subclass 457 visa. The court also addressed the application of the doctrine of precedent, specifically the *ratio decidendi* of Federal Circuit Court judgments in migration matters, outlining the criteria for such judgments to be binding.
