Andreas Vogeler has written a book on free choice of law in the European Private International Law of non-contractual obligations (Die freie Rechtswahl im Kollisionsrecht der außervertraglichen Schuldverhältnisse. Tübingen, Mohr Siebeck 2013). The official summary reads as follows:
With the codification of Art. 14 of the Rome II Regulation, European lawmakers harmonized the exercise of party autonomy for non-contractual obligations in European law. Andreas Vogeler does a systematic study of party autonomy in the framework of international private law, at the same time providing recommendations for politics and practical use.
