Re Tyler & Ors; Ex parte Foley

This matter concerned an application for a writ of prohibition brought by Mr Foley against Group Captain C.A. Tyler AM and other members of a General Court Martial, who were the President and members of that court. The dispute centred on the scope of legislative power to authorise the executive to use armed force for the execution of laws, as opposed to its primary defensive function.

The High Court was required to determine the proper construction of provisions, both in the United States and Australia, that confer power on the legislature to control the circumstances under which the executive may deploy armed forces for the purpose of executing laws. This involved considering whether such provisions were intended to grant a broad power or to impose specific restraints on the executive's use of force for law enforcement.

The court examined the historical context and purpose of similar provisions, referencing a United States statute enacted around the time of the American Constitution, known as the George Washington Act of 1792. This Act provided that the President could call forth the militia to suppress combinations obstructing the execution of federal laws, but only upon notification by a judge that ordinary judicial proceedings were insufficient. The court noted that this statutory framework demonstrated a legislative concern to restrain the executive's use of armed force for law enforcement, requiring judicial notification and imposing limitations on the deployment of militia from other states. The provision also included a "sunset" clause, indicating a temporal limitation on the Act's operation.
