The applicant was severely autistic, and unable to consent to medical treatment. He had been admitted voluntarly to a mental hospital and detained under common law powers. The Hospital trust appealed a finding that his detention had been unlawful.
Held: He had in fact been detained: ‘We do not consider that the judge was correct to conclude that L was ‘free to leave’. We think that it is plain that, had he attempted to leave the hospital, those in charge of him would not have permitted him to do so.’ and ‘In our judgment a person is detained in law if those who have control over the premises in which he is have the intention that he shall not be permitted to leave those premises and have the ability to prevent him from leaving. We have concluded that this was and is the position of L.’ The 1983 Act created a complete regime which excluded the application of the common law doctrine of necessity. The judgment was sustained.
