The European Court of Justice continues to deliver a great many important judgments which contribute to the rapid development of EU law. However, it can be difficult to understand the significance of many of these judgments unless they are accompanied by explanatory commentaries. This second edition contains over one hundred important cases on the topics of freedom of movement of goods, services, persons, and capital. All these cases are accompanied by comments and questions, encouraging more in-depth thought about each of the judgments and their effects. The book has been compiled for use in connection with courses studying the rules of the internal market, but it is also recommended reading for those who are interested in obtaining a more informed insight into the Courts practice in relation to the four fundamental freedoms of the EC Treaty.
