Guy represents many local and international companies in their litigation and arbitration disputes and has acquired a wealth of experience in several sectors including banking, insurance, media and telecommunications, energy, environment and transport.

He specialises in all forms of urgent injunctive relief, freezing orders and other forms of legal measures that serve to protect our clients’ interests.

Work highlights

Guy has led the Dispute Resolution team in Luxembourg on a wide range of high-profile disputes. These include advising:

  • Luxair, the national carrier, and its insurers in proceedings before the Luxembourg Supreme Court on indemnification and statue of limitation issues arising from a plane crash in 2002. The trial was broadcast live in different courtrooms, which was a first in Luxembourg judicial history
  • Enel Luxembourg, the subsidiary of Italy's largest power company, in a challenge to prevent a ruling of an Albanian court being enforceable in Luxembourg. The Luxembourg case is part of a multijurisdictional battle involving proceedings before the European Court of Human Rights and proceedings in France, Ireland, the Netherlands, Italy and the U.S.
  • a subsidiary of the Indian company, ArcelorMittal, in a dispute over carbon emission rights. At the time of writing, the case is likely to result in a landmark decision by the European Court of Justice on the interpretation of EU legislation on the greenhouse gas emissions scheme
  • SOTEL, a subsidiary of ArcelorMittal, in administrative and Court of Appeal proceedings that resulted in SOTEL succeeding in its bid to build an underground high voltage line against opposition by the environmental activist group, Greenpeace, and local residents
  • Paul Wurth, the Luxembourg-based international engineering company, in its challenge to ministerial decrees that would have resulted in the establishment of a drug rehabilitation centre opposite the company’s global head office in Luxembourg. The company has offered alternative sites at its own expense
  • the Russian Federation in national enforcement proceedings of an ICC Award initiated by the Swiss company Noga before the Luxembourg courts
