Other countries--and I'm looking to Australia and the United Kingdom--have either a public appointments commission, a merit commission, or a public service commission. The U.K. has now put their public appointments commission into their civil service commission, making it a public service commission, but they all have members from those organizations chair the selection committees.
The principle has to be that members of Parliament are confident that it is a fair selection process, and the reason you go for some of these independent organizations, such as our commission or a public appointments commission, is to get that kind of assurance.
I don't really know how the full appointment processes work in these other areas. I think it will be up to the committees that will be hearing from those nominations and reviewing them to feel comfortable with how the selection committees are struck.
