[Monsters, Inc] How does Waternoose have the extrajudicial power to banish monsters? There should be some sort of legal process for this, right?

He doesn't. What he does have, however, is a lot of money and political clout for being such a key energy provider. Waternoose most likely expected to be able to cover up any disappearances with a great deal of bribes and other payments to the right hands to make any investigations go away.

It's very doubtful the monster judicial system considers exiling people to alternate realities as fitting punishments. Especially since they're convinced Earth is full of horribly toxic children. It would be cruel and unusual to the extreme. It's best to leave all travel to trained professionals who know better than to contaminate themselves. 

From what little we've seen of the monster world, they probably have a legal system very similar to ours, where incarceration/rehabilitation are the norm, all done within their world exclusively.
