The eleventh edition has been fully updated and partially expanded again, without this affecting the overall scope. Where the updates have taken up more space, this has been compensated elsewhere by deletions or smaller print. The underlying concept of the textbook remains unchanged. It continues to aim to convey all the necessary knowledge for the compulsory subject area by enabling a quick and compact acquisition of the fundamentals of European law. In the numerous footnotes, updated references to literature and case law can be found, allowing for a deeper exploration of the legal issues addressed. To facilitate a quick review of the material, review questions have been printed at the end of the concise textbook, along with formulated answers to these questions.
