Tommy Pettersson is hailed by sources as “one of the most experienced competition lawyers in the Swedish market” who “always provides very insightful advice”.


In addition to being a partner of the law firm Mannheimer Swartling for 25 years, founding the Brussels office of the firm, Tommy was responsible for the firm’s practice group on EU and Competition for many years. His counselling has involved cartel and abuse of dominance investigations by the European Commission and national competition authorities; as well as competition law proceedings in Swedish courts, in the EU courts and in arbitration cases.  Moreover, Tommy has been acting in several state aid matters before national courts and the European Commission and he provides advice in relation to merger control. He has been involved in many merger control notifications to the Swedish Competition Authority, the European Commission and other competition authorities. Tommy also gives advice on general EU law, for example free movement of goods and Brexit issues.

He has written numerous articles and spoken at several seminars on the subject of EC and competition law. For many years, he has also been engaged as a judge in the European Law Moot Court Society.

Representing both national and international clients, Tommy’s long-time experience adds up to a great diversity of practicing EU and competition law.
