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.

Shell: landmark decision regarding international collective settlement of mass claims

On 29 May 2009, the Amsterdam Court of Appeal delivered a landmark decision regarding an international collective settlement of mass claims. This decision is the first international application of a mechanism under Dutch law that facilitates collective settlements of mass claims. The vast majority of the potential claimants in this case did not reside in the Netherlands and were spread across the globe. This case concerned a settlement agreement entered into by, among others, Shell Petroleum N.V. and The “Shell” Transport and Trading Company Limited (collectively: “Shell”) with respect to the recategorisation of certain of its oil and gas reserves in 2004. The settlement agreement was entered into for the benefit of the worldwide group of Shell’s shareholders, excluding all US shareholders, who purchased their shares in the period between 8 April 1999 and 18 March 2004 on any stock exchange other than the New York Stock Exchange. The Amsterdam Court of Appeal has now declared this settlement agreement binding on all shareholders to which it applies according to its terms. De Brauw acted as legal counsel to Shell in this matter.Team Sjoerd Eisma, Rob Polak, Martijn Polak, Marnix Leijten

EU Parliament approves new collective redress mechanisms for consumers

On 24 November 2020, the European Parliament endorsed a new directive on representative actions for the protection of the collective interests of consumers ("Collective Redress Directive" or "CRD"). The CRD is part of the "New Deal for Consumers", an initiative to strengthen EU consumer law enforcement and to modernise EU consumer protection rules. The CRD introduces new cross-border and domestic redress mechanisms allowing collective actions against traders for violating a broad range of EU laws, such as data protection, travel and tourism, financial services, energy and telecommunications. The CRD will enter into force 20 days after its official publication. Member states will then have two years to implement the directive and a further six months to apply the new provisions. This means that these changes are expected to be in full effect in the EU from mid-2023 onward.
