That's ultimately for other people to decide. My advice would be, I don't see how it's an upgrade. You have an officer of Parliament with superior court powers. You have a methodology. You have a track record. You have the training. There's not the slightest possibility of partiality or bias. It's the instrument you chose to create, as an officer of Parliament, to deal with ethics issues. In its simplest version, why do you need another instrument?
