Piepkorn, Ex parte

This matter concerned an application by Piepkorn for a writ of habeas corpus, brought before Gummow J in chambers. The applicant sought to challenge the legality of his detention.

The central legal issue before the Court was whether the applicant's detention was lawful, specifically in relation to the validity of the warrant under which he was held.

Gummow J considered the provisions of the *Migration Act 1958* (Cth) and relevant case law concerning the requirements for a valid detention warrant. His Honour found that the warrant in question was defective and therefore did not provide a lawful basis for the applicant's continued detention.

Consequently, Gummow J ordered that the applicant be discharged from custody.
