Sir Harry Gibbs Constitutional Law Moot 2025

The ANU Law Students' Society is proud to host the 2025 Sir Harry Gibbs Constitutional Law Moot, Australia’s leading national constitutional law mooting competition for university students.

Since its inception in 2002, the Gibbs Moot has earned a reputation as a premier forum for aspiring advocates to grapple with complex and often topical questions of constitutional law.

Each year, the competition challenges participants to prepare written and oral submissions on a hypothetical case grounded in live constitutional issues. Many moot problems have been crafted by current and former High Court Justices and Solicitors-General, ensuring the moot’s continued rigour and relevance. This year, the current Solicitor General, Dr Stephen Donaghue KC, has once again kindly agreed to draft the problem question.

Named in honour of Sir Harry Talbot Gibbs GCMG AC KBE QC, who served as a Justice of the High Court of Australia from 1970 and as Chief Justice from 1981 to 1987, the moot continues to celebrate his enduring legacy in Australian constitutional jurisprudence.

Previous Editions of the Gibbs Moot

Gibbs 2024

The New South Wales Parliament has enacted the War on Waste Act, requiring households to install Methane Monitors in rubbish bins and pay a levy of 10 cents per gram of methane produced by domestic food waste. Logan Roy, a Sydney resident, refuses to comply, resulting in a $3,800 levy and a subsequent $5,000 “Do the Right Thing” notice from the Commonwealth’s Waste Advisory Agency, established under its own federal Act to support compliance. Roy challenges the laws in the High Court, raising two constitutional questions: whether the NSW levy is an invalid duty of excise under s 90, and whether the federal Agency exercises judicial power contrary to Chapter III of the Constitution.

The problem question was drafted by the Solicitor-General of Australia, Dr Stephen Donaghue KC.

The Moot was hosted by Melbourne University and the Melbourne University Law Students’ Society.

The University of Technology Sydney (Grace Strik, Gina Tran, and Ryan Little) won the Grand Final.
