Murray Smith and Conflict of Interest

It is rather interesting why the other side to the story of Murray Smith accepting outside employment while being a government (political) appointment.

What about the other government MLA's who are working in a variety of jobs, while still sitting MLA's. Some even chairing or sitting on Standing Policy Committees of the Legislature.

Ever wonder why Mark Hlady was able to be an active investment councillor and sit on the various committees he did, even as chair?

How many other MLA's do this, and why? Do they not have enough to do as full time MLA's?
