Igoe v Major General Michael Ryan Am in his capacity as a Reviewing Authority (No 2)

In the matter of Igoe v Major General Michael Ryan AM in his capacity as a Reviewing Authority (No 2), the applicant sought judicial review of a sentence of imprisonment and dismissal from the Defence Force imposed by a service tribunal under the Defence Force Discipline Act 1982 (Cth). The High Court was asked to determine whether the sentence was lawfully imposed and whether the reviewing authority's confirmation of the sentence was proper. The case involved the application of sentencing principles from the Crimes Act 1914 (Cth) as incorporated by reference from the Defence Force Discipline Act.

The central legal issues were whether the service tribunal and the reviewing authority misapplied sentencing principles, and if so, whether the court should exercise its discretion to issue prohibition, certiorari, and related relief. The court had to consider the conceded jurisdictional errors and the appropriate circumstances for making such orders. This involved a review of the constitutional and statutory framework governing military justice and the application of judicial discretion in such cases.

The court held that the service tribunal and the reviewing authority had indeed made jurisdictional errors by misapplying sentencing principles. The court exercised its discretion to grant the relief sought by the applicant and the Chief of Army. The sentence was quashed and remitted to a different Defence Force Magistrate for reconsideration according to law. Additionally, the court ordered the second respondent to pay the applicant's reasonable standard costs.

The final orders made by the court were that the applicant be granted leave to amend the application to seek an order prohibiting the first and second respondents from executing the Warrant of Commitment to Imprisonment dated 27 May 2020, the first and second respondents be prohibited from executing the warrant, the decision of the first respondent dated 27 May 2020 be quashed, the decision of the third respondent (the sentence decision) dated 20 April 2020 be quashed, the sentence decision be remitted to a different Defence Force Magistrate to be considered and decided again according to law, and the second respondent pay the applicant’s reasonable standard costs fixed at $15,200 inclusive of GST and disbursements.
