Personally, I can't say that I would, because, again, as I've said, there is something about the word “estimates” that causes a kind of blanching of the complexion of members of Parliament, by and large. You can just see them thinking about what other direction they could go in. That's just my personal experience.
Because of the fact that, again, within the formal estimates process there isn't anything very visible or interesting to be done, for the most part, I'm not sure why you'd create a separate estimates committee, unless there is a sufficient supply of parliamentarians who are in the bad books of their colleagues and you want to send them off to the committee equivalent of Siberia or something.
Anyway, thinking again about what Parliament can do, I think in order to do persuasive work on estimates, first of all, within the constraints—I see many volunteers at this table—of the estimates process, which requires you to send a message back that you can't even explain, I wouldn't be thinking of particularly somehow investing more time or more committee apparatus in the formal estimates process.
But what any committee can do...if there's a program that looks like it warrants study, that can be done outside the estimates process. I think that's where the potential for more influence is.
