What Others Say

Global Competition Review

Boutique firm Zippro Meijer stands out with its focus on plaintiff litigation in the Netherlands, where it has become a significant player. Comprising managing partners Erik-Jan Zippro and Rogier Meijer, along with partner Sander Timmerman and one associate, the firm boasts a client roster one would expect to see at a much larger firm. It is working with Hausfeld on various Trucks cartel follow-on damages claims, and is handling more than 20 proceedings in the Netherlands for its clients. It is also representing Deutsche Bahn and several subsidiaries in a damages claim against a pre-stressed steel cartel, and is defending Samsung in follow-on damages claims before Dutch courts for allegedly participating in cartels to fix the prices of cathode ray tubes. - GCR100, EU Claimants Bar, 20th Edition, January 2020

GCR named Zippro Meijer as the only recommended Dutch law firm for its European Claimant category, noting: "A small yet significant player, the boutique firm Zippro Meijer stands out with its unique focus on plaintiff litigation in the Netherlands." - GCR100, EU Claimants Bar, 2018
