Or rather, why do some of them seem to trump the law?
If a celeb has done something eg an affair, I sort of understand how a superinjunction can be in place in order to protect kids and ensure no weirdo fans do something awful to any of the parties.
HOWEVER, why are they allowed if the celebrity has broken the law?
Surely the law should be the priority? Or am I misunderstanding these situations? Are there potentially investigations ongoing, but the superinjuction only prevents the press etc reporting on them?
