No, my point is that the Uk government has the right to intervene if there is a breakdown in the rule of law. I do, of course, argue that this happens daily despite the supposed reforms that are going on in the Crown Dependencies of Guernsey, Jersey and the Isle of Man. Their legal systems are used, quite blatantly, to undermine the rule of law in the UK and in very many other countries around the world, including a great many in the developing world where as yet any form of information exchange with the Crown Dependencies is almost non-existent.
The UK Govt has the right (and duty) to intervene if the rule of law breaks down in the Crown Dependencies. This is not the same as stating that the UK has the right or duty to intervene if Crown Dependency law conflicts with something that we desire to happen in the UK.
In other words, they mean if rampaging mobs start stringing up accountants from the lamp posts, not if accountants aid people in dodging UK taxes.
