In 2014, Professor Halberstam co-organized and chaired substantive discussions at a joint meeting in Luxembourg of the Court of Justice of the European Union and the U.S. Supreme Court. In 2015, he co-organized and chaired a closed-door working group in Berlin of high-level European policymakers and officials on EU accession to the European Convention on Human Rights.
