Jacobsen & Anor v Rogers

The High Court of Australia heard an appeal in the matter of Jacobsen & Anor v Rogers. The appellants, Johannes Jacobsen and Terence, were represented by Mr. E.M. Heenan, QC, and Mr. H.D. Seymour. The respondent, Rogers, was represented by the Solicitor-General for Western Australia, Mr. K.H. Parker, QC, and Mr. R.E. Cock, with the Attorney-General for Western Australia intervening. The Commonwealth Attorney-General intervened in support of the appellants, while the Attorneys-General for South Australia, New South Wales, Queensland, and Victoria intervened in support of the respondent.

The central legal issues before the High Court concerned the interpretation and application of section 10 of the Commonwealth Crimes Act. The appellants argued that the Full Court had erred in its reasoning by concluding that the application of section 10 to federal authorities and premises was unnecessary for the enforcement of federal criminal laws. They also contended that the Full Court had incorrectly inferred from certain provisions of the Crimes Act, specifically section 85ZQ, that the Act did not apply to the Crown in the right of the Commonwealth, and by extension, to the States. Furthermore, the appellants challenged the Full Court's view that the sanctity of confidential State documents, such as Cabinet papers, made it inconceivable for a police officer to use section 10 for their seizure, even in the absence of other protections.

The appellants' submissions were grounded in the principle that the primary objective of statutory interpretation is to ascertain the legislature's actual intention. They referred to the High Court's decision in *Bropho* (1990) 171 CLR, which indicated a move away from rigid interpretative approaches towards a more nuanced understanding of legislative intent, particularly in light of modern governmental operations, including those in the commercial sphere. The appellants argued that the Full Court's reasoning failed to adequately consider this principle and applied interpretative rules, such as *expressio unius est exclusio alterius*, without sufficient discrimination.
