High Court, in habeas corpus proceedings, directs the immediate release of an individual who was involuntarily admitted to an approved centre under statute, the court finding that the admission order was deficient as it failed to adequately explain how the statutory criteria for "mental disorder" were met; and the initial application for involuntary admission also did not provide sufficient reasons as required by law, particularly since it was made by a person not specified under the applicable statute.
