The Commission of Inquiry into Possible Illegal Activities and Associated Police Misconduct (the Fitzgerald Inquiry; 1987–1989) into Queensland Police corruption was a judicial inquiry presided over by Tony Fitzgerald QC. The inquiry resulted in the resignation of Queensland's premier, Joh Bjelke-Petersen, the calling of two by-elections, the jailing of three former ministers and the Police Commissioner (who also lost his knighthood). It also contributed to the end of the National Party of Australia's 32-year run as the governing political party in Queensland.
