Rather than commenting on the opinion, I'll just comment on a technicality.
A way to make something seem more clear is to never make a short list that gives you one out of four choices. Just make it a really short list so that it's one out of two, or something much, much shorter, so that people can't debate why he picked this one instead of that one.
The Ontario Court of Justice, the Ontario court, has an excellent appointment process. I have to say that even within that, the Attorney General does make choices, but people don't debate the choices.
