This short textbook on EU competition law reflects my teaching experiences as a guest lecturer at Martin Luther University Halle-Wittenberg. The author is most grateful to Professor Christian Tietje for giving him the opportunity to teach competition law in one of the master programmes of the university without which this book would not have been written. Huge thanks also have to be extended to Professor Thomas Lübbig of Freshfields Bruckhaus Deringer who allowed me to gather the practical experience with EU competition law that is also incorporated in this book. The author is indebted to Julia Dietrich of Frontier Economics for kindly agreeing to write the section on the economic foundations of EU competition law for this book. Valuable contributions have also been made by Mariusz Motyka-Mojkowski, Uwe Salaschek and Sebastian Zachow. The views and errors expressed in this book are entirely my own.
