Tomas and his corporate litigation team have a systematic approach to risk management and use risk assessments as a central reporting tool. He has significant experience in the dialogue with insurance companies, investors and other stakeholders that, in addition to the parties directly affected, are also to be kept informed about the ongoing development in strategy and results. For more than two decades, Tomas has assisted the Danish Ministry of Defence and the Danish Ministry of Defence Acquisition and Logistics Organisation (DALO) in the area of defence and security in many of Denmark's most strategic and politically significant procurements. He is an advisor in demand with particular expertise in Article 346 TFEU and the Defence and Security Directive and has contributed to developing the legal framework for quick defence procurements, establishing national production capacity and negotiating key contracts on strategically important defence systems. Moreover, Tomas provides advice on export controls, investment monitoring and complex contractual relationships between governmental and international operators, including key operators in the area of security policy. Tomas is a certified arbitrator with experience as both a single judge and as a member of arbitration tribunals sitting in panels under the ICC and SCC and under ad hoc rules. He has a right of audience before the Danish Supreme Court and is recognised by Chambers Global as one of Denmark's leading litigators. The combination of litigation experience, strategic insight and a deep understanding of the special needs of the defence sector and legal framework makes him an advisor in demand in the cross field between law, security and politics.
