Die Haager Principles on Choice of Law in International Commercial Contracts – Eine weitere Verankerung der Parteiautonomie

Jahrgang 79 () / Heft 3, S. 624-653 (30)

The Hague Conference on Private International Law has recently drawn up »Principles on Choice of Law in International Commercial Contracts«. An innovative feature of these Principles, which are accompanied by an explanatory Commentary, is that unlike an international convention they are non-binding. The Principles were drafted by a Working Group, which commenced in 2010, and by a Special Commission of November 2012. The instrument was approved by the Council on General Affairs and Policy in March 2015. The Principles' relatively few black-letter rules (12 articles and a preamble) seek to encourage choice of law in international commercial transactions. They contain clarifications and innovations on choice of law, particularly for jurisdictions where party autonomy is not accepted or is accepted only in a restrictive manner. The Principles try to achieve universal application and also to influence existing regional instruments such as the Rome I Regulation of the European Union and the OAS Mexico Convention. Developing the Principles was a demanding task since they apply not only to courts but also to arbitral tribunals. Since party autonomy is the centrepiece of the Hague Principles, freedom of choice is granted basically without restriction. The Principles clarify important issues for agreements on choice of law. A reference to »law« also includes generally accepted »rules of law«. The latter refers to principles developed by international organisations or international conventions. This approach is also applicable to courts. Under the Hague Principles the parties' choice of law is severable from the main contract. Express and tacit choices are accepted. There is no requirement as to the formal validity of a choice of law. An innovative solution also tries to find an agreement on choice of law in the case of a battle of the forms. Not only are international mandatory rules of the forum respected but under certain circumstances mandatory provisions from other sources are also taken into account. The extent to which overriding mandatory rules and public policy are applied or taken into account, however, is ultimately a matter not for the non-binding Principles themselves but for other rules. The Hague Principles declare themselves to be an international code of current best practice with respect to the recognition of party autonomy in choice of law in international commercial contracts. Their acceptance in international practice will show how far the expectations of The Hague will be met.
