There is such a right where I live too, but there is an exception: when the release of that information is thought to be harmful to that individual. I can certainly imagine how allowing a paranoid person suffering from delusion, to read the unfiltered medical notes of their psychiatrist, could be quite harmful. I don't know how often this actually comes up; I read the report of the last psychiatrist I saw in its entirety. They always suggest you shouldn't. Probably right about that. "Subdued affect"? Ouch.
