X v MHRT for NI  NIQB 1,  MHLO 31
In previous judicial review proceedings, X had established that in NI where there is a mandatory duty to discharge it cannot lawfully be deferred. He now sought to bring a negligence and false imprisonment claim against the Tribunal and the Trust for his detention during a six-week deferral period. To sue the Tribunal he required leave of the High Court (under Article 133 Mental Health (Northern Ireland) Order 1986, the equivalent of s139): the test is whether on the materials immediately available to the court the complaint deserves fuller investigation. Leave was refused because there had been a difficult question of statutory construction and no bad faith or lack of reasonable care.
