Eh? I thought it was a scenario where de jure she has power (I believe one of her powers is the authority to refuse to legitimise a law, as she has to sign it does she not?), but de facto she can never use it because parliament would remove the monarchy if she did. I was under the impression she held the same authority in the commonwealth realms but for the reason that they would remove her as their figure head she couldn't use it.

[url=http://en.wikipedia.org/wiki/Governor_General_of_Canada]We have the Governor General[/url], who represents the Queen. He or she does technically have the authority to veto a law/bill, but it would be considered a gross misuse of power to do so and there's only a select few times where it's even happened here that I can recall, because democracy. Basically the only way the populace here would tolerate him vetoing a law is if it was extremely controversial and there were questions about whether it was legitimately passed or not. Otherwise it's subverting democracy, which would be bad. [b]Very bad[/b]. So his post is primarily just to oversee the house of commons to make sure it keeps its shit in the cage and not on random pedestrians, and to listen to the queen go "Canada? What's a Canada?"
