Work highlights
Represented EET Group in a landmark transfer pricing dispute before the Supreme Court. This ruling set a significant precedent in Danish transfer pricing law, reinforcing taxpayers' rights to rely on compliant documentation and arm's length benchmarks.
Assisted RWE in a landmark transaction establishing a strategic partnership with the world's largest sovereign wealth fund, Norges Bank Investment Management, which includes the sale of a 49% stake in the Thor offshore wind project - Denmark's largest offshore wind farm project and a key renewable energy infrastructure development in Northern Europe.
Represented two board members before the Eastern High Court in a landmark case concerning the deductibility of damages paid due to directors' liability stemming from the financial crisis. The judgment is the first to consider the deductibility of operational losses under the provisions of the 1922 State Tax Act and sets an important precedent, helping to clarify fundamental principles in Danish tax law. The Ministry of Taxation has not appealed the decision, which is now final.
