I'm very much in favour of standards. I think there should be rules such that there must be a smooth transfer of service from doctors who do not wish to participate to those who will. That's a heavy burden to put on doctors who object, but it's important, because these are vulnerable people at the end of their lives who must not be left dangling because their doctor does not want to provide this service to them.
So principles, yes, but as to specific regulations, I don't know.
