Gorrissen Federspiel was opened in 1869 by a Danish Supreme Court attorney and has since undergone a number of mergers to become one of the country’s largest firms.

The foundations for its international arbitration practice were laid in the 1930s, when legacy firm NJ Gorrissen began working on commercial disputes in the maritime insurance and energy sectors. NJ Gorrissen would later merge with another firm that opened that decade, Per Federspiel, which is said to have been the first Danish practice targeted at international clients.

Today, the firm’s 28-strong disputes practice is led by Henriette Gernaa, a dual-qualified lawyer who acts as both counsel and arbitrator and is a board member of the Danish Arbitration Association. Lotte Eskesen leads the practice in the Danish city of Aarhus.

Other names to know are Jacob Skude Rasmussen, a former Danish diplomat who acts in banking and finance, IT and professional liability disputes; and Kenneth Hvelplund Pedersen, who specialises in M&A disputes and is described as a rising star.

Who uses it?

Gorrissen Federspiel has several clients in the financial sector, including Carnegie Investment Bank, Danske Bank, Deutsche Bank and Morgan Stanley. It has also represented accountancy firms Deloitte and Pricewaterhouse Coopers.

Other users are HBO Nordic and Maersk Oil. The firm also reports advising the Danish Institute of Arbitration and the Danish Institute for Human Rights.

Other past work includes representing a construction company in a dispute over a UK project; a transport company settling an arbitration over delivery of faulty equipment; and a client in a FIDIC arbitration with a state.
