Private autonomy is a fundamental principle of civil law - even more against the background of increasing Europeanisation. How is this principle implemented in the Proposal for a Common European Sales Law (CESL), in German and in Polish Law? Read the informative proceedings of the international conference on "e;Private Autonomy in Germany, Poland and Europe"e; held at the University of Leipzig. The topics of the volume range from fundamental aspects, such as the term autonomy as a "e;legal axiom"e;, to specific issues like the freedom of contract in the CESL and the control of unfair contract terms in business to business transactions.
