"Treacy J held that the supervision of this appellant was with legal authority and lawful and that the 1986 Order did authorise the guardian to take the impugned measures in the circumstances of this case. Subsequent to his decision the Supreme Court examined the concepts of deprivation of liberty and restriction of liberty in the case of patients suffering from mental health difficulties in Cheshire West and Chester Council v P  UKSC 19,  MHLO 16. It is unnecessary for us to set out the facts or reasoning in that decision. It is, however, now accepted by the Trust that the guardianship order did not provide any mechanism for the imposition of any restriction on the entitlement of the appellant to leave the home at which he was residing for incidental social or other purposes. ... Mr Potter on behalf of the appellant in this case recognised that this left a lacuna in the law. That gap had been filled by Schedule 7 of the Mental Health Act 2007 in England and Wales which introduced deprivation of liberty legislation into the Mental Capacity Act 2005 providing a mechanism for the lawful restriction on or deprivation of liberty of a person such as the appellant. It is clear that urgent consideration should now be given to the implementation of similar legislation in this jurisdiction."
