"One of the major effects of the European law to English legal system is on direct applicability or direct effect. For instance, the British constitution establishes that parliament is sovereign. This means that no other law in Britain that are above laws made by the government. Relative to its sovereignty it is clear that Parliament is the highest legislative authority in UK: only Parliament can create law, No court in UK can impede or restrict Parliament’s law making ability. Parliament can make whatever laws it wants, and the courts must apply that law, Parliament’s sphere of legislation has no limits; it can legislate on any matter of its choosing (E.g. retrospective legislation) and No parliament can bind a future Parliament. Therefore, Parliament can make or cancel any law it chooses, and the courts must enforce it. However, membership of the EC has compromised this principle (Reich 2005).
According to the primary law of the European community set in the treaty of Rome in 1957, * all the primary laws of the treaty affect all the member countries and Great Britain is not exceptional. Treaty of Rome is superior to all domestic laws and other laws from individual states should concur with it. This contradicts the sovereignty of the Britain Parliament* which is believed to be above other legal systems (Aziz 2004).
