De Brauw advises DAF Trucks as lead counsel in extensive EU antitrust follow-on damages litigation in 19 jurisdictions

On 19 July 2016, the European Commission imposed fines totaling EUR 2.93 billion on five truck manufacturers, including DAF Trucks. De Brauw represented DAF Trucks throughout the Commission’s investigation. Thereafter, massive follow-on litigation ensued with thousands of legal proceedings in multiple European and non-European jurisdictions as a result. The cases vary from damages for a few trucks to collective proceedings in which hundreds of millions are claimed. DAF Trucks and PACCAR have appointed De Brauw to act as lead counsel in all of the 19 jurisdictions that are involved. This mass claim is of unprecedented scale, arguably the most complex and extensive ever in Europe, and requires close oversight to align strategy in all these different legal systems, including common and civil law systems. De Brauw developed its own 'mass claim platform' for this case, creating one central data, document, proceedings and compliance portal for all of those working on the connected proceedings, all over the world. This is a prime example of the international nature of De Brauw's practice.

De Brauw assists and represents Ageas in settlement ruling by Amsterdam Court of Appeal

De Brauw advises and represents NAM (Shell/Exxon) in events surrounding earthquakes

De Brauw advises and represents NAM (Shell/Exxon) in the events surrounding the earthquakes. 900 Private individuals and 12 housing associations, represented by Stichting Waardevermindering door Aardbevingen Groningen (WAG) have submitted a mass claims suit, holding NAM liable for the damage following from the earthquakes and demanding that NAM compensate the decrease in value of their homes as a result of these earthquakes. In addition, De Brauw represents NAM in the administrative law proceedings before the Council of State in which more than 50 applicants have brought legal action against the extraction plan based on the Mining Act (regulating both the way NAM extracts gas from under the ground and the extent of the production), and in other cases arising from earthquakes caused by gas extraction. Safety risks are the greatest matters of concern in these proceedings. For more than two years, Marnix Leijten, Jan de Bie Leuveling Tjeenk, René van Tricht, Arne Münch, Sander Rijsterborgh and Dulijon Veldhoen have been working on the civil law proceedings and Nicolien van den Biggelaar, René van Tricht and Kees Saarloos have been working on the administrative law proceedings. Marnix Leijten: "This matter is a fine example of how we can provide clients with integrated advice on several interrelated issues including the Mining Act, civil law and administrative law proceedings and mass claims suits. It is exactly the strong point of our litigation practice, in which many different areas of expertise come together in this type of highly complex issues." Judgment on the case that was before the District Court of Assen will be rendered in 12 weeks. The session before the Council of State will be held on 10 and 11 September 2015.
