Brownlie v Environment Protection Authority of New South Wales

The applicant, Geoffrey Robert Brownlie, sought special leave to appeal to the High Court of Australia against a decision of the Court of Criminal Appeal of New South Wales. The dispute concerned the operation of criminal statutes from two states, Queensland and New South Wales, which purportedly applied to the same conduct by Mr Brownlie – the application of insecticide to his cotton crop. The applicant argued that this situation presented a sharp focus on competing criminal statutes and the potential for such laws to affect the same person and transaction.

The central legal issue before the High Court was whether the laws of New South Wales could validly apply to conduct that occurred in Queensland, particularly in the context of criminal statutes. The applicant contended that the New South Wales legislation, by seeking to punish conduct occurring outside its territorial boundaries, relied on a doctrine of "State interest" that should be rejected. This, it was argued, would undermine the principle that "all crime is local" and lead to anti-federal consequences by allowing some states' criminal legislation to extend beyond their borders based on perceived interest, rather than territorial connection.

The applicant's submission was that the approach taken by New South Wales in its legislation was contrary to federal principles. They argued that the maxim "all crime is local" retained significant force and that allowing a state to criminalise conduct occurring in another state based on a notion of "State interest" would create an imbalance and undermine the federal structure. The applicant sought to challenge the Court of Criminal Appeal's decision on three grounds, aiming to prevent the application of New South Wales criminal law to Mr Brownlie's conduct in Queensland.
