2025 OECD Competition Open Day - Session 2. Rethinking the Standard of Proof in Competition Law
The standard of proof is a core concept of competition law; it is the degree to which enforcers must prove their case to succeed in establishing the existence of a competition infringement or an anti-competitive merger. With the increasing complexity of establishing antitrust infringements, has the evidentiary standard been set too high? Could it be making it excessively difficult for competition authorities to prove their cases or block mergers? What about in assessments where concepts such as economic moats and entrenchment are involved? Should the standard of proof or the burden of proof be adjusted in the future?
This session moderated by Antonio Capobianco (Deputy Head, OECD Competition Division) brought together Daniel Haar (Chief, Appelate Section US DOJ), Marc van der Woude (President, General Court of the EU) ad Soo-jin Kang (Professor of Law, Korea University) to try to answer these questions.
