As it happens, I work a lot around issues of Mental Capacity in my day to day work so I have more than a passing interest in the dealings of the Court of Protection. The Court of Protection, you see, has a hand in many of the issues that might relate to decisions that are made in relation to people who lack capacity.
The Court of Protection is generally closed. The reasons being (and I make no judgement of the rightness or wrongness of this) is to protect those whose personal business arises in the court. As it relates to people who lack capacity in general, they are not able to make a decision about the reporting, or not, of their personal lives as they unfurl in the court and usually have not personally taken the active decision to go to court so should not (the argument goes, I suppose) deal with the publicity that surrounds it.
