Can a Royal personnage be protected by the Image Rights (Bailiwick of Guernsey) Ordinance 2012? How would one balance the rights of free speech and free press with the economic and dignitary interests of the Royal personnage? Does the European Convention on Human Rights have a role to play in this balancing act? If the Queen is not above the law, then neither should the law be beneath her.
