The function of the Review Board is to review the detention of patients in centres designated under the Criminal Law (Insanity) Act 2006. Currently the Central Mental Hospital is the only designated centre in the country.
The detention of patients who have been referred to the Central Mental Hospital arising from a decision by the Courts that they are unfit to stand trial or, having been found not guilty of an offence by reason of insanity, is reviewed by the Board.
The Board is also responsible for reviewing the detention of prisoners, including military prisoners, who have been transferred to the Central Mental Hospital suffering from mental disorders.
The Mental Health (Criminal Law) Review Board is an independent statutory body which was established by order of the then Minister for Justice, Equality and Law Reform under Section 11 of the Criminal Law (Insanity) Act 2006 on 27 September 2006.
