M v An NHS Trust  MHLO 39 (UT)
"[T]he tribunal's decision was made in error of law, but not [set aside]. In my grant of permission, I identified two possible errors of law. ... One of those errors was that the tribunal's reasons might be inadequate for being 'long on history and evidence but short on discussion.' ... There is, in truth, only one thing that really has to be said about the quality of reasons, which is that they must be adequate. Everything else is merely application of that principle to the circumstances of a particular case. ... [T]he second possible error [is] that the 'tribunal's reasoning shows that it was confused about its role and the [relevance] of a community treatment order'. ... [T]he reasons at least leave open the possibility that the tribunal may have strayed outside its proper remit. ... The first three sentences read: 'A cardinal issue of this application is whether the patient should be discharged from hospital by a CTO. This issue involves knowledge of the nature of a CTO. A CTO may only be imposed by the patient's RC ...' It may be that the judge did not express himself clearly, but that passage appears to begin by suggesting, and to continue by denying, that the tribunal had power to make Mr M subject to an order or was being asked to approve that course. The judge did then make a distinction between discharge from hospital and discharge from the liability to be detained. So it is possible that his reference to 'discharge from hospital by a CTO' may have been intended, not as a direction about the tribunal's powers on the application, but as a statement of how the responsible clinician envisaged Mr M's eventual progress. This interpretation would be consistent with what the tribunal said later ... In view of Mr M's current status [he had been discharged], I do not have to decide whether those reasons do or do not show that the tribunal misdirected itself. I limit myself to saying that it is risky if reasons can be read in a way that indicates a misdirection. ... Given that Mr M is no longer liable to be detained, I can see no need to venture outside the appropriate role of the Upper Tribunal in mental health cases and state, even in the form of a narrative declaration, that the tribunal should have exercised its power to discharge him. That is why I have exercised my power to refuse to set aside the tribunal's decision regardless of any error of law that it may have made."
