In 1972, when Heath decided to take Britain into the Common Market, he used Parliament's legal sovereignty to deny and permanently limit the political sovereignty of the electorate. Heath and Parliament changed the basic rules and they did not have the right (legal or moral) to do that. The 1972 European Communities Bill wasn't just another Act of Parliament. Heath's Bill used Parliament's legal sovereignty, and status as representative of the electorate, to deny the fundamental rights of the electorate.
