Yes.
Opposition parties will say nasty things about the current government and vice versa, and some of the things that are said are exaggerated. I proposed and acted on a proposal to amend the members' code. It's not in the act but a member is not allowed to make false statements. There's a little provision in there, and I've forgotten exactly how it reads now. That was a problem, when people would make baseless allegations.
It doesn't happen all the time. Obviously whichever party you're in, you're looking to find the foibles of the other party; that's politics but it shouldn't go too far.
