The Criminal Law (Sexual Offences) Act 2006 is an Act of the Oireachtas (Irish parliament) which was passed to plug the hole left by the Supreme Court decision in which struck down as unconstitutional a seventy-year-old provision on statutory rape. The Act provides for a defence of honest mistake where, if a defendant can satisfy the court that he or she honestly believed that the person with whom the sexual activity was committed, was of consenting age at the time (which the Act now sets as seventeen years old for both sexes). The lack of such a defence in section 1(1) of the caused the Supreme Court to declare that section void.
