This book provides a detailed analysis of the objectives, principles and methods of EU Internal Market law. It focuses on the substantive law of the Internal Market, the strongest, most developed and most original part of EU law.

The authors introduce the reader to the legal peculiarities of EU Internal Market Law: its sources, instruments, methods of interpretation, effects, and the relationship between Union and national law (Introductory Chapter). They also acquaint the reader with the acquis communautaire: the case law of the European Courts and secondary EU legislation.

From this starting point the book takes the reader to the issue of personal application of EU law: from being only a law for market citizens (individuals acting in the market) EU law has become the law for all citizens and residents living in Member States (whether they are active market participants or not). Thus, EU law determines everybody’s everyday rights and duties alongside (and occasionally overriding) existing national law (Chapter I). This is based on the principle of equal treatment.
