First off, that's a rare occurence. As every regular here on Community Central will tell you, people who claim to be that kind of user are dime a dozen. And they rarely if ever are. "Truth" is a highly subjective term, as people are unconsciously biased in their own favor.

Because figuring out whether it's actually true or not is next to impossible, the decision is left with local admins, and their fate is left with the local community. If a blocked user thinks (s)he's right, but the community doesn't agree/doesn't want to punish the admin, then nothing's going to happen.
