As a result of allegations of improper conduct by Burke during his time as premier, the WA Inc royal commission was established in 1991. This led to Burke being charged with various offences, for which he was sentenced to two years' imprisonment. He served seven months in jail in 1994 for travel expense rorts before being released on parole. In March 1997, he was sentenced to three years' jail for stealing $122,585 in campaign donations. He served six months before the convictions were quashed on appeal. In 1995, he was stripped of his 1988 honour as a Companion of the Order of Australia.
