Yes. If I found out they hadn't disclosed, I would investigate or do something.
The existence of a rule certainly goes some way in having it complied with. What I don't want is a situation of people keeping mum about possible offers and they get one week out and there are no obligations under the act for them to tell me anything. I'm just trying to plug a couple of little loopholes there.
It is a short period of time, and for most public office holders it's only one year. But I still think it would be useful to have a rule like that to draw their attention to the fact that they have these post-employment obligations.
