Ilkka Leppihalme

Partner Ilkka Leppihalme has more than a quarter of a century of experience in competition law – including also in Brussels. He has been involved in various landmark competition cases, including the largest cartel cases in Finland and many ‘first-ever’ situations. He possesses significant experience in both national and multijurisdictional merger control procedures across a wide range of industries as well as in foreign direct investment (FDI) control.

Leppihalme has represented clients in numerous significant competition law related damages cases. He defended two companies in the precedent-setting asphalt cartel damages cases until the end of the hearing in the Helsinki Court of Appeal – all of the claims against both companies were dismissed.

Leppihalme has been a Non-Governmental Advisor to the International Competition Network – a network of more than 130 competition authorities – since 2010. He was one of the few members of the Competition Law Expert Group of the Finnish Bar Association in 2010-2024. He is a regular chairman and speaker at competition law conferences and seminars, including being chairman of Finland’s biggest annual commercial competition law conference annually since 2009.
