Practice Areas

Prof. Dr. Jos Dumortier is an internationally renowned top expert in data protection and ICT law.

Back in the ‘90s, he was one of the first Belgian lawyers to deal with data protection, long before other lawyers started practising this area of law. At that time he was appointed by the Belgian Government to draft the Belgian Data Protection Act.

Regarding IT law, he has particular expertise in digital marketing, e-business, e-government, electronic signatures, e-security, digital archiving and legal support of business process re-engineering.

Prof. Dr. Dumortier is widely known as the go-to lawyer for the public sector in these areas of law. He very frequently acts as counsel to the Belgian Federal Government, the Belgian Federal Public Service of Information and Communication Technology, the Flemish, Walloon and Brussels Governments, the European Commission, the Dutch goverment and various other Belgian and international public sector bodies to draft contracts or provide advice in these areas of law.

Academic Activities and Memberships

Since 1993, Jos Dumortier has been a Professor of  Law at the Law Faculty of the University of Leuven, where he teaches data protection, IT and telecommunications law.

In 1990, he founded and became the first Director of the Interdisciplinary Centre for Law and Information Technology (ICRI) at the University of Leuven.

He is a research director in the Belgian Institute for Broadband Technology (IBBT).

Together with the Belgian Minister of Justice, he was also the driving force behind the launch in 2011 of the Belgian Cybercrime Centre of Excellence for Training, Research and Education (B-CCENTRE). This Centre aims to be the main platform for collaboration and coordination with regard to cybercrime matters in Belgium, combining expertise of industry players,  academic research groups and public organisations (law enforcement, judges and policymakers).

For more than ten years he was an editorial board member of Computerrecht, the leading Belgian-Dutch law journal on IT and data protection law.

He is the author of numerous books and articles and is a much sought-after speaker at national and international seminars and conferences in the area of data protection and IT law. He is the Editor of the International Encyclopedia of Cyberlaw (Kluwer International Publishers) and editorial board member of various specialized publications.
