Balog v Independent Commission Against Corruption; Stait v Independent Commission Against Corruption

The High Court of Australia heard appeals from Tibor Balog and Conrad George Stait against the Independent Commission Against Corruption (ICAC). The dispute concerned the interpretation of the Independent Commission Against Corruption Act 1988 (NSW) (the Act), specifically regarding the definition of "corrupt conduct" and the ICAC's investigative functions.

The central legal issues before the High Court were whether the ICAC's investigative powers extended to conduct that merely "may" have occurred or was "connected with or conducive to" corrupt conduct, and how this intersected with the requirement that corrupt conduct must also constitute or involve a criminal offence. The appellants sought to limit the scope of the ICAC's jurisdiction, while the respondent argued for a broader interpretation of its investigative mandate.

The Court was required to construe sections 8, 9, and 13 of the Act. Section 8 defines corrupt conduct, while section 9 stipulates that such conduct must also constitute or involve a criminal offence. Section 13 outlines the functions of the ICAC, including investigating circumstances implying or allegations that corrupt conduct "may have occurred, may be occurring or may" occur, and investigating conduct connected with or conducive to corrupt conduct. The appellants contended that the "may" in section 13(a) and the broad language in section 13(b) were not intended to expand the definition of corrupt conduct beyond that established in sections 8 and 9. The respondent argued that these provisions conferred a wide investigative remit, allowing the ICAC to investigate matters that were not yet definitively corrupt conduct but were related to it.
