Weyer specialises in competition law and leads Houthoff’s Competition practice group. He is also head of Houthoff’s Healthcare sector group. Weyer focuses in particular on merger notifications and cartel defence litigation. His work involves issues relating to regulation and competition in healthcare, and advising and assisting healthcare institutions in the context of partnerships.

Weyer represented T-Mobile Nederland in the ‘mobile operators case’ brought by the Netherlands Competition Authority, which eventually resulted in the seminal ‘T-Mobile case’ at the European Court of Justice on the definitions of object and effect in the context of internal market restriction. He also represented Accell Groep, the second largest bicycle manufacturer in Europe, in an appeal against a decision of the Netherlands Competition Authority regarding alleged mutually agreed concerted practices in the form of information exchange. In relation to merger control, he was involved in the EU notification of TomTom’s takeover of TeleAtlas. In relation to healthcare, he assisted the mergers of the ErasmusMC and Havenziekenhuis, the St. Elisabeth Hospital and TweeSteden Hospital, the Kennemer Gasthuis and Spaarne Hospital, and the AMC and VUmc.
