AH vs West London Mental Health Trust was a landmark case in England, which established a legal precedent in 2011 when Albert Laszlo Haines (AH), a patient in Broadmoor Hospital, a high security psychiatric hospital, was able to exercise a right to a fully open and public mental health review tribunal to hear his appeal for release. The case and the legal principles it affirmed have been described as opening up the secret world of tribunals and National Health Service secure units, and as having substantial ramifications for mental health professionals and solicitors, though how frequently patients will be willing or able to exercise the right is not yet clear.
