Short Profile

Dr Simon Weise is an associate at GLADE MICHEL WIRTZ in the COMPETITION practice. He advises German and international clients on all aspects of German and European competition law. His practice focuses on national and international merger control proceedings including matters of foreign direct investment control, advising complex cooperations between competitors, questions of distribution antitrust law as well as advising on general compliance matters.

From 2007 to 2012, he studied law at the Heinrich Heine University Düsseldorf with a focus on competition law. Afterwards, he worked as a research assistant at a chair for European and International Law at the HHU while working on his doctorate thesis, which deals with the interplay of state liability and merger control. During his legal clerkship, which he accomplished from 2015 to 2017 in the district of the Higher Regional Court of Düsseldorf, he worked for the German Federal Cartel Office and in the antitrust team of a leading international law firm. In 2022 and 2023, Simon Weise was honored by Best Lawyers in cooperation with Handelsblatt in the category "Ones to Watch" in the field of antitrust law. He is a native speaker of German, fluent in English and has basic knowledge of French.

Simon Weise is a member of the Studienvereinigung Kartellrecht e.V., the Antitrust Group of DICO – Deutsches Institut für Compliance e.V. and the Düsseldorf Moot Association (DMA) e.V. Moreover, he is committed to the exchange among young business lawyers in Düsseldorf as a member of the board of the JDWA – Verein Junger Düsseldorfer Wirtschaftsanwälte e.V.
