As I indicated previously with the five-year prohibition, my experience is that the definition is working. There have been no challenges in cases where I have decided not to continue.
Parliament was quite specific as to why it should be a period of five years and who should be covered. What I mentioned earlier that may be worth consideration is if it's covering the right.... For example, right now you are covering students who might go work as an intern in a minister's office for five years, if they're hired under section 128.
I'm not sure if that's what was intended.
