I guess for extradition request, they have to prove that he's commited a crime in their country.
And for it to be granted a whole other set of things have to be proved beyond reasonable doubt. (Or it's arranged behind closed doors and then the facts are set posteriori.
EDIT: Scratch that about the request, seems like they can request one for any old bollocks.
