What are the administrative mechanisms that would give reality to that notion of their being arm's length? What is there to confirm that it wouldn't merely be a political appointment? After all, it's an at-pleasure appointment, reporting directly to the minister, designed no doubt to control costs but certainly having ramifications for independence. That's why the tribunals are so concerned.
You're saying, no, don't worry, it's not going to be like that because there are instruments that confirm the arm's length relationship. I'm asking what those instruments are.
