Peter E. Stassen

Attorney-at-Law (L)
Partner
LL.M.
Peter specialises in European competition law, with a particular emphasis on high-profile and complex M&A-related competition law and other regulatory issues.

Peter has considerable experience with the regulatory side of M&A processes, and particularly with European, Danish, and multi-jurisdictional merger control matters. Peter has led a number of high-profile merger control processes involving businesses within a range of complex industries (including biotech, financial services, aviation, infrastructure, energy, and IT services), including several processes involving the design of remedy packages. Peter is particularly well-versed in providing strategic and deal certainty analyses of prospective transactions, is regularly advising on foreseeing and handling call-in risks, and also advises on all other transaction-related competition law issues, including how to handle the practical challenges associated with integration planning. As part of his regulatory practice, Peter also advises on Foreign Direct Investment (FDI) and Foreign Subsidies Regulation (FSR) issues, and has experience with handling state aid law considerations related to transactions involving public authorities and public undertakings.

Peter also regularly advises on matters related to abuse of dominance, including how to organise distribution systems and agreements to avoid pricing and discrimination abuse. He has extensive experience in public procurement law, particularly in the medical and pharmaceutical industries, as well as large-scale infrastructure and energy projects.

Peter is admitted to appear before the High Courts of Denmark, and in 2021 held an interim judgeship with the High Court of Eastern Denmark. Peter is also an experienced lecturer, having served as an external lecturer at King's College London from 2017–2020.

Peter believes that in an increasingly complex regulatory scene, in order to truly create value for the client in large transactional projects three things are key: Teamwork, recognising the need for cross-disciplinarity (for instance, involving our in-house competition economics experts or our M&A colleagues), and understanding the client's core commercial and industry-specific challenges.
