WWL says

Heiner Kahlert comes in for high praise thanks to his outstanding knowledge of sports law and his work advising and representing clients in complex contentious proceedings.


Dr Heiner Kahlert is a partner at Martens. Founded by the late Dr Dirk-Reiner Martens, the firm has established itself as one of the top sports law firms in Europe. For more than a decade, Heiner has been advising international and national sports federations, leagues, clubs, athletes and other stakeholders in sports on a wide range of subject-matters.

A particular focus of Heiner’s sports law practice is on arbitration and litigation. As counsel, he frequently appears before the Court of Arbitration for Sport, adjudicatory bodies of federations and German courts. For instance, in recent times, Heiner successfully defended the International Skating Union (in the landmark case against Claudia Pechstein) and the World Bridge Federation (in the “coughing scandal”) against very significant damage claims. Moreover, Heiner regularly sits as arbitrator, in particular at the German Court for Sports Arbitration and the Permanent Court of Arbitration of the German Ice-hockey Federation.

Another core part of Heiner’s practice is advising federations on their statutes and regulations, not only from a purely legal perspective but also on broader aspects of good governance and compliance. In addition, he frequently negotiates and drafts complex agreements, often in relation to the staging of major sports events, sponsorship deals or the commercialization of data or other content. Heiner’s expertise on association law and contract law covers both German and Swiss law. Moreover, he advises on matters of European competition law and fundamental freedoms.

Heiner frequently teaches on sports law and arbitration. He has also authored numerous publications in those fields. Heiner is fluent in German and English and speaks conversational French and Arabic.
