Adrien de Hauteclocque
Adrien de Hauteclocque is a Senior Counsel at the Paris and Brussels offices of Geradin Partners, with over fifteen years of experience in EU competition, State aid and regulatory law. He focuses in particular on complex disputes in regulated sectors, involving the interplay between competition law and sector-specific regulation. He advises and represents clients in energy, infrastructure and digital markets, as well as in antitrust proceedings and economic sovereignty matters involving State aid, foreign subsidies and industrial policy. His practice encompasses proceedings before national courts and authorities, the European Commission and the EU Courts. It also extends to private enforcement, including collective actions and funded damages claims on behalf of companies and public entities harmed by anticompetitive practices.
Prior to joining Geradin Partners, Adrien spent fourteen years at the General Court of the European Union, as a référendaire (Senior Court Advisor) from 2011 to 2019 and as Head of Cabinet to the President of the Court from 2019 to 2025, leading a Cabinet of 27 staff, including 15 senior lawyers. As a référendaire, he drafted preliminary opinions, judgments and orders in competition, State aid, energy, trade defence and intellectual property cases. As Head of Cabinet, he contributed to the legal analysis and preparation of deliberations in Grand Chamber proceedings and interim measures cases, supervised selected cases, and oversaw the Cabinet’s institutional and inter-institutional work.
Combined with his training in both law and economics, this experience gives him unusual first-hand insight into how judges assess economic evidence and review the decisions of the European Commission, competition authorities and sector regulators, and into how litigation strategy and regulatory policy interact.
Alongside his practice, Adrien is a Part-time Professor at the European University Institute’s Florence School of Regulation, a Visiting Senior Fellow at the London School of Economics and Political Science and an Associated Researcher at the Governance and Regulation Chair of Paris-Dauphine University. He serves as a non-governmental advisor to the European Commission within the International Competition Network and is a member of the Training Advisory Board of the Council of European Energy Regulators. He has published extensively on EU competition, State aid and energy law, including as co-editor of Capacity Mechanisms in the EU Energy Markets (Oxford University Press), State Aid and the EU Energy Sector (Hart) and EU Competition Law and Energy Markets (Edward Elgar, sixth edition forthcoming).
Adrien holds a PhD in Law from the University of Manchester and a Master’s in economic policy from the University of Strathclyde, and is a graduate of the EM Lyon Business School Grande École programme. He has also completed postgraduate studies in data, artificial intelligence and digital law at Sorbonne University. He is a member of the Paris Bar and speaks French and English.
