I'm really delighted to host this guest blog by Allan Norman, Principal Social Worker & Solicitor at Celtic Knot (www.celticknot.org.uk), an independent law firm and social work practice. Allan's post explores how very different real life outcomes can follow a capacity assessment where a person might make an unwise decision, and asks whether we would want the law to be that way if we were the subject of a capacity assessment. Guest posts responding to this question, or on other capacity and social care topics, very much welcomed.
A capacity decision can be, as I tell my students, like a fork in the river. You have to go one way or the other. If a person has capacity, they are allowed to make unwise decisions. If a person lacks capacity, we must make decisions for them in their best interests. Which fork we take is particularly significant if they lead to completely different destinations - that is, the unwise decision that they would have made is the opposite of what we think is in their best interests.
Caselaw is developing some tools for ameliorating the worst effects of this, for example laying emphasis on how a person's previously expressed wishes may form part of their best interests. Meanwhile, I have argued, if you control the capacity question - what is the decision, the making of which has to be assessed - you have significant control over the answer.
