Confronting Race, Chapter III and Preventive (In)justice: Garlett v Western Australia

Tamara Tulich and Sarah Murray

On 7 September 2022, the High Court handed down its decision in Garlett v Western Australia [2022] HCA 30 (Garlett) upholding, by a 5:2 majority, the validity of item 34 of Sch 1 of Div 1 of the High Risk Serious Offenders Act 2020 (WA) (HRSO Act) on the basis that it did not infringe the principle established in Kable v Director of Public Prosecutions (NSW) [1996] HCA 24 (Kable). The constitutional reasoning of the High Court in Garlett follows the pattern of Vella v Commissioner of Police (NSW) [2019] HCA 38 (Vella) and Minister for Home Affairs v Benbrika [2021] HCA 4 (Benbrika) with Gageler J and Gordon J dissenting from the rest of the Court in relation to the constitutionality of the risk assessment role being conferred on ‘courts of a State’. However, the case also provides important new insights on Chapter III of the Commonwealth Constitution (Ch III) in that a minority of the Court identified a role for the principle established in Chu Kheng Lim v Minister for Immigration, Local Government and Ethnic Affairs [1992] 176 CLR 1 (Lim) beyond the federal court context to state courts and, relatedly, new strands of convergence in Ch III jurisprudence. .
