Book excerpt: Examination of Party Autonomy and its limits has always raised fundamental questions in national contract and private law. The concentration on information solutions which enhance and leave more space to party autonomy is a fundamentally new approach to this core issue and is typical of Community legislation. The complexity of the question made it advisable to have the different aspects treated and discussed by specialists in different areas: by legal scholars and economists, by EC law and by contract law specialists, by scholars from different jurisdictions with different regulatory approaches and backgrounds. The four parts deal with (1) the economic and constitutionell foundations of the question, with (2) the framework to be found in EC treaty law, with (3) the fundamental and more general aspects relating to substantive EC contract law legislation, and with (4) the most important individual legal measures. The book covers both general contract law (with consumer contracts) and labour contract law.
