ROGER Welsh (Letters February 17) makes a very valid point about people not understanding the implications of the Treaty of Rome (European Communities Act 1972). Many think that the Metric Martyrs? case was just a petty argument about whether we should be able to buy our bananas etc by the pound. There was however a major constitutional issue at stake here ? who?s laws take precedence in our country, British or EU ones? The judge in the Martyrs? case summed up thus: ?We are now living under a new legal order. The 1972 European Communities Act was a one-off, not an ordinary treaty ? but a new way of life. ?These are new constitutional powers. The British parliament surrendered its sovereignty in 1972 ? European laws have overriding force with priority over British laws. . . The articles on the supremacy of the British Parliament are now only of historical perspective ? they are non-binding.? Or to put it more simply ? Brussels rules Britain. Graham Palmer Lambs Park Sheepstor
