CEO Customs v Granite Arms Pty Ltd & Anor

The Chief Executive Officer of Customs (CEO) appealed to the High Court of Australia against a decision of the Federal Court of Australia concerning the importation of certain firearms by Granite Arms Pty Ltd and another party. The dispute centred on whether the firearms were "prohibited imports" under the *Customs (Prohibited Imports) Regulations 1956* (Cth) and, consequently, whether the CEO was entitled to seize and forfeit them.

The High Court was required to determine whether the firearms, specifically certain models of semi-automatic rifles, fell within the definition of "prohibited imports" as defined by Regulation 4 of the *Customs (Prohibited Imports) Regulations 1956*. This involved interpreting the scope of the prohibition on the importation of firearms that were "designed to discharge a projectile by the action of an explosive and are of a kind that is capable of being readily converted to a fully automatic weapon".

The Court considered the meaning of "readily converted" in the context of the relevant firearms. It examined expert evidence regarding the technical modifications required to convert the semi-automatic rifles to fully automatic operation. The judges applied principles of statutory interpretation, focusing on the plain meaning of the words used in the regulation and the evident purpose of prohibiting certain types of firearms. They concluded that the firearms in question were not of a kind that could be "readily converted" to fully automatic weapons within the ordinary meaning of that phrase, as the conversion would require significant modification and was not a simple or straightforward process.

Consequently, the High Court dismissed the CEO's appeal, upholding the Federal Court's decision that the firearms were not prohibited imports.
