On Monday, the United States signed the 2005 Hague Convention on Choice of Court Agreements. John B. Bellinger did the honors in one of his final acts as Legal Adviser to the Secretary of State. The United States is the only country that has signed the Convention. Mexico is the only party to the Convention, having acceded to it in September 2007. Thanks to Conflict of Laws .net for noting this.
This was a fitting way to end Bellinger's distinguished term as Legal Adviser.
