Wikipedia
Sovereign immunity, or crown immunity, is a legal doctrine by which the sovereign or state cannot commit a legal wrong and is immune from civil suit or criminal prosecution. This principle is commonly expressed by the popular legal maxim "rex non potest peccare," meaning "the king can do no wrong."
In constitutional monarchies the sovereign is the historical origin of the authority which creates the courts. Thus the courts had no power to compel the sovereign to be bound by the courts, as they were created by the sovereign for the protection of his or her subjects.
