Professor Peter Edge from the School of Law, Oxford Brookes University, UK, is, an expert on Manx constitutional law. In this special comment, he sheds some light on the unique constitutional status of the Crown Dependencies. For Parliament to act in what it sees as the interests of the UK citizens who elect its members is, in one sense, uncontroversial. For much of the British Empire, this could be, and often was, at the expense of those living in territories controlled by the United Kingdom, but not incorporated into it. This included the Crown Dependencies. The statutory purchase of the Isle of Man by the UK in 1765, for instance, was carried out in order to protect UK customs duties at the expense of a very substantial Manx trade which the UK categorised as smuggling.
