This article analyses the decisions on public policy contained in the Kluwer Arbitration database. The database includes more than 1,000 cases. Objections based on public policy have been raised in 44% of recognition and enforcement proceedings and in 38% of setting aside proceedings. The success rate of these objections was low, 19% and 21%, respectively. This article discusses the decisions in which these objections were successful, distinguishing between the three International Law Association categories: (i)‘violation of fundamental principles, procedural public policy, or substantive public policy’; (ii) ‘loi de police’; and (iii) ‘violation of international obligations’ (though there were no successful objections in this category). The article concludes that the Kluwer Research confirms that public policy should only be applied in a limited set of circumstances, though it also features a few exceptions to the narrow construction of the concept of public policy.
