RM suffers from a severe mental impairment. On 2 March 2018, RM was charged for a series of violent and sexual offences. RM was found unfit to plead to the charges but was held to have committed the alleged acts.
The Crown Court imposed a Hospital Order and a Restriction Order on RM. RM was detained in a psychiatric ward in hospital.
On 16 January 2019, RM made an application for discharge to the Tribunal. The expert medical evidence before the Tribunal indicated that RM would shortly begin receiving treatment outside of hospital in a community-based setting as part of a period of testing.
Under Article 78 of the Order, a patient may only continue to be detained if they are suffering from a mental disorder of a nature or degree which warrants their detention in hospital for medical treatment.
The Tribunal acknowledged that RM's care plan would involve him moving to live in a community-based setting but considered that he would nonetheless remain a patient receiving treatment in hospital.
RM brought an application for judicial review of the decision of the Tribunal arguing that his continued detention was unlawful in light of the treatment plan advanced in medical evidence which did not envisage further treatment in hospital.
The High Court dismissed the appeal upholding the decision of the Tribunal. However, the Court of Appeal overturned the decisions of the Tribunal and High Court holding that they had erred in law. The Tribunal and Department of Justice now jointly appeal to the Supreme Court.

Lorna Armstead ('LA') hired a car from Helphire Ltd ('Helphire'). LA signed Helphire's standard hire contract, confirming that (a) she would pay Helphire for any damage to the vehicle and (b) she would pay Helphire a daily rate for any loss of use of the vehicle if it was unavailable to Helphire because it was damaged.
LA was in a car accident whilst driving the hired car. The accident was caused by the negligent driving of a third party who was insured by Royal & Sun Alliance Insurance Company Ltd ('RSA'). The hired car required repairs, for which LA paid. Helphire subsequently requested that LA pay £1,560 for the loss of use of the hired car while it was being repaired. LA brought a claim against RSA for both sums. In the three courts below, LA's claim for £1,560 sum was dismissed.
