Section 92A of the Criminal Code (Qld) requires the prosecution to prove that, but for the officer's improper purpose (intent to dishonestly gain a benefit or cause a detriment), the officer would not have acted as they did. It is not sufficient to prove merely that the officer held a dishonest intent at the time of the acts; the improper purpose must have been causative of the conduct. Where a public officer acts with both a proper purpose and an improper purpose, the offence is only committed if the officer would not have engaged in the same conduct absent the improper purpose.
