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, and the jailing of three former ministers and the Police Commissioner Terry Lewis (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.
