This book investigates the normative foundations of European contract law by applying contemporary political theories to evaluate its current trajectory and future development. Martijn W. Hesselink, a scholar in European private law, utilizes a framework of political philosophy to critique existing legal structures. He argues that the harmonization of contract law in the European Union requires a clear articulation of the underlying political values that should guide legislative and judicial decision-making.

Legal scholars frequently cite this work as a significant contribution to the debate on the constitutionalization of European private law. Experts highlight the text for its rigorous integration of political theory into the practical study of legal harmonization.
