Lenz & Staehelin was formed in 1991 when Conrad Staehelin’s Zurich firm merged with Raoul Lenz’s Geneva practice. Both arms of the firms already had experience of arbitration going back decades before the merger. The team on the Geneva side included the late Robert Briner, who served as a judge at the Iran-US Claims Tribunal in the 1980s and went on to be chairman of the ICC International Court of Arbitration and a renowned arbitrator.

These days the group is headed by partners Xavier Favre-Bulle in Geneva and Harold Frey in Zurich, who both sit as arbitrators. The team is split evenly between the two cities (there’s also an office in Lausanne) and includes five partners and three counsel who do arbitration full-time as well as four other partners and a team of more than 20 counsel and associates.

Who uses it?

The firm acts for states and state-owned entities in international disputes. It also has private clients from industries including pharmaceuticals, energy, telecoms, construction, financial services and luxury goods. The list includes some well-known Swiss blue-chip companies and multinationals.

Unfortunately, few of the firm’s clients are on the public record but it is known to be advising Romanian state entity Hidroelectrica in a dispute with energy trader EFT. Going further back, it advised Deutsche Telekom (in a dispute with Vivendi) and Turkey’s Çukurova group (in a dispute with Teliasonera).

It regularly co-counsels with international firms on large matters with a Swiss angle. The firm also frequently appears on behalf of sports federations in cases before the Court of Arbitration for Sport and related Swiss court actions.

Track record

One spectacular result for the firm came in 2016 when it helped a government in the Middle East to defeat a claim for more than US$1.5 billion in damages, as well as a claim for the issuance of a long-term concession. The client also received a large part of its costs.

It has helped four of the most important industrial groups in Germany defeat a billion-dollar claim by a US company; and successfully defended the manufacturer of a desalination plant in a subcontractor dispute, winning costs.

For a healthcare company, it helped to settle a multibillion-euro dispute over the termination of licence and supply agreements – agreeing terms that allowed the client to maintain the business relationship.

Another highlight saw the firm represent an Irish company in a successful Geneva arbitration against a Libyan state entity over the use of a fibre optic cable across the Mediterranean.
