The Public Policy Exception Under the New 2019 HCCH Judgments Convention

Abstract

The public policy exception is inherently a fluid device. Its content is basically left to each State. A shared public policy is an exception. Therefore, the obligation of uniform interpretation, as provided in Article 20 of the 2019 Judgments Convention, will have an inherent limit here. Moreover, the Convention leaves some important issues, including procedure, to national rules. Each requested State retains a discretion to invoke the Convention grounds of refusal in a concrete case, and on whether to make an ex officio inquiry or have the parties prove those refusal grounds. The Convention also provides for the concrete applications of the public policy exception, following the model of the 2005 Choice of Court Convention. Here, a purely grammatical reading may create some peripheral problems, especially with the specific defences of conflicting judgments and parallel proceedings. Solutions may be found in the method of purposive interpretation and some general principles, particularly the evasion of the law and the abuse of rights, before resorting to the public policy defence.
