I guess it would depend on what type of government contract. Say you had an interest in a company in Vancouver that sold tires to the Department of Transport and then you were a lobbyist in Ottawa. If the two things didn't touch, I suppose that would be awfully difficult to justify. On the same point, if you talk about someone who is paid as a lobbyist and who is also giving communications advice on similar issues with the same people, that's obviously a fair issue for the public to scratch their heads and be concerned about. I guess it would be how you'd construct ways to grapple with that.
On the first issue, there is a right of appeal to the Court of Appeal under Bill C-2, and you can also seek a judicial review of a tribunal decision.
