Marcin Lewoszewski is a legal counsel, member of the District Chamber of Legal Counsels in Warsaw. Before joining the firm, he worked for over seven years as a part of the TMT team of CMS Cameron McKenna Olswang Nabarro in Warsaw. Earlier, for two years, he worked for the Polish Data Protection Authority. He is recognised by Chambers and Partners as one of the leading data privacy lawyers in Poland (currently Band 2), as well as Legal 500 as leading individual.

Currently, Marcin represents before the Supreme Administrative Court a party to the proceedings ended with the imposition of the first financial penalty in Poland by the Polish DPA on a controller whose activity is based on the scrapping data from publicly available registers (the Dun & Bradstreet / Bisnode vs the DPA case).

In 2016, he was appointed the IAPP KnowledgeNET Poland chair by the International Association of Privacy Professionals, a globally operating organisation of data protection professionals. For two years, he was member of the IAPP Publications Advisory Board.

In the past, the Dziennik Gazeta Prawna daily named him one of the 30 most promising lawyers in Poland before 30 years of age.

Marcin authored several dozen articles on the subject of personal data protection: he published, among others, in the Polish edition of Harvard Business Review, in Rzeczpospolita daily, Dziennik Gazeta Prawna, and abroad – in BNA Bloomberg, IAPP PrivacyTracker or DataGuidance. He is the co-author of the chapter in the book on Polish data protection regulations “The Law Reviews: the Privacy, Data Protection and Cybersecurity”. He was quoted on numerous occasions by both Polish and foreign professional press, including the opinion-forming Politico. Regardless of his work for the firm, he was the editor-in-chief of the quarterly Information in Public Administration, published by C.H. Beck.
