Since its formation the European Union has expanded beyond all expectations, and this expansion seems set to continue as more countries seek accession and the scope of EU law expands, touching more and more aspects of its citizens' lives. The EU has never been stronger and yet it now appears to be reaching a crisis point, beset on all sides by conflict and challenges to its legitimacy. Nationalist sentiment is on the rise and the Eurozone crisis has had a deep and lasting impact. EU law, always controversial, continues to perplex, not least because it remains difficult to analyse. What is the EU? An international organization, or a federation? Should its legal concepts be measured against national standards, or another norm? The Oxford Handbook of European Union Law illuminates the richness and complexity of the debates surrounding the law and policies of the EU. Comprising eight sections, it examines how we are to conceptualize EU law; the architecture of EU law; making and administering EU law; the economic constitution and the citizen; regulation of the market place; economic, monetary, and fiscal union; the Area of Freedom, Security, and Justice; and what lies beyond the regulatory state. Each chapter summarizes, analyses, and reflects on the state of play in a given area, and suggests how it is likely to develop in the foreseeable future. Written by an international team of leading commentators, this Oxford Handbook creates a vivid and provocative tapestry of the key issues shaping the laws of the European Union.
