This week the Queensland opposition launched a robust attack on a centuries-old criminal law defence.
The 'mistake of fact’ defence was encoded into Queensland law in 1899 when our Criminal Code was first enacted, adopting a common-law notion dating back at least as far as pre-Norman England, that criminal liability requires some sort of actual subjective culpability, whether based on moral guilt or negligence. Section 24 of our Code provides that a person who does something under an honest and reasonable, but mistaken, belief as to a particular fact, they are not criminally responsible to any greater extent than if that belief was correct.
