Abstract
The ultimate authority to rule on the interpretation of European Union law resides with the Court of Justice of the European Union. This paper discusses the ECJ in detail, with particular attention paid to its history. Also discussed are its relations to Great Britain and France, as well as relevant problems the ECJ faces today.

From the Paper
"Historically, Britain's Parliament held the position of supremacy in the country but this is currently challenged by the right the ECJ to rule on whether British law is compatible with European Union law (Curtis 110). The notion that a body of laws supersedes British Law and that Britain is bound somewhat to the written constitution of the European Union creates a problem in the minds of many British people, both those within the government and common citizens (Curtis 110).
The European Union (at this time the European Community) challenged British Parliamentary sovereignty in 1991 when the EC threatened to take legal action to stop British Rail construction projects for environmental reasons (Curtis 110)."
