If someone is does not have mental capacity to make their own decisions, one of those decisions they are not capable of making is whether to cooperate with a test to see if they have capacity to make their own decisions.
I would have thought that was self evident.
I find it incredibly frustrating for a court case to proceed on the grounds that lack of mental capacity has not been proved, when it never will be if the person has to agree to be assessed.
Surely there has to be some way around this. Surely it could be made legal for a GP to state they have concerns about the mental capacity of a patient, and that should be enough for a court to assume the person does not have mental capacity UNLESS they agree to take an assessment which proves they do!
