Parliamentary supremacy has had its day.

The origins of Parliamentary Supremacy are found in the 17th century, in particular the enactment of The Bill of Rights, 1689. This is, according to Dicey "the very keystone of the law of the constitution."1 Prior to this it was within a courts jurisdiction to challenge the validity of an Act of parliament, such as in Dr Bonham's case, 1610.2 Therefore it would appear that any subsequent upset of this well-established doctrine would prove to be extremely damaging. The occurrence of Parliamentary supremacy is largely due to the lack of a written constitution in the United Kingdom, as written constitutions provide certain entrenchments (such as in the case of Germany) regarding limitations of scope for creating legislation. European community law, by virtue of the European Communities Act 1972, now has direct applicability in the United Kingdom. Subsequently, where there is any conflict between an Act of parliament and community law, the later takes precedence. In other words, Parliament is no longer the sovereign law making authority; it must instead adhere to Community law, in theory forfeiting its sovereignty. However due to the courts only enforcing Acts of parliament, not treaties such as the Treaty of Rome, it can be argued that by parliament retaining the power to repeal any Act that has not been entrenched, it could repeal the 1972 Act, effectively withdrawing itself from the European Union. This would of course be politically and economically incomprehensible, but in theory Parliament still retains its ultimate sovereignty as the highest form of law. Despite this, adherence to community law does limit the scope by which British Parliament can legislate, as can be found in Factorame Ltd and others v Secretary of the State for Transport3. Due to the Merchant Shipping Act 1988, ships, owned by companies with directors from other European community member countries were no longer eligible for registration as British Vessels. Whilst seeking a provisional ruling from the European Courts of Justice, the divisional court granted interim relief from the 1998 Act. Thus by doing so the courts were effectively suspending an Act of parliament, contrary to Dicey's statement that ".... no person or body is recognised by the law of England as having a right to override or set aside the legislation of Parliament".4 Therefore, by granting interim relief it could be argued that the courts were simply acknowledging European supremacy.

The applicability of the European Convention on Human Rights in the Human Rights Act 1998 has in someway redressed the lapse of Parliamentary Supremacy as has been discussed above. Instead of the courts being able to override an Act of Parliament with community law the conflicting statute can only be declared as incompatible. From there on the matter is to be taken up by the executive, who must decide how to remedy the incompatibility.

The Scotland Act 1998 has also brought about issues of the applicability of Parliamentary Supremacy in the modern day. One of the devolved powers given to the Scottish Parliament is that to repeal any Act, be it enacted by United Kingdom Parliament or by the Scottish Parliament, so long as it is only applicable to Scotland. Supposing the United Kingdom enacted an Act for Scotland, Scottish Parliament could repeal it & enact its own Act in the place of the former Act. In theory this action of repealing could continue without end. Here there are two supreme parliaments, ...
