Royal Borough of Greenwich v CDM  EWCOP 15
"In this case the patient is CDM, a lady aged 63 years. ... My Conclusions: (i) I conclude that CDM lacks capacity to conduct proceedings, as is agreed on behalf of CDM. (ii) I conclude that she does not have capacity to make decisions about her residence. ... (iii) By the end of the case the parties agreed that I should consider care and treatment separately. CDM carries out her own self-care, with encouragement, in the care home. I am not satisfied that she does not have the capacity so to do. There will be some occasions when she makes appropriate decisions, for example accepting insulin from the nurse, but there are many other occasions when she makes manifestly unwise decisions as a result of her personality disorder which impairs her ability to follow professional advice, whether in respect of her residence or treatment. I therefore accept Dr Series' evidence that when making appropriate decisions she has capacity but when making manifestly inappropriate decisions she lacks capacity. (iv) Property and affairs: I am troubled by the lack of evidence on this issue. ... I do not think I have any satisfactory evidence on which I can conclude that she lacks capacity in this area. (v) I conclude that she lacks capacity to surrender the tenancy of her property. This decision is intimately bound up with her ability to make decisions about residence. ... It follows and I so find that CDM lacks capacity in relation to the question whether or not she should be accommodated in CC (being the relevant hospital or care home) for the purpose of being given the relevant care or treatment. I therefore authorise her continued detention and deprivation of liberty in CC. ... This means that a further hearing will be required both to establish a mechanism under which the local authority can operate when capacity fluctuates and also to consider best interests."
