Zeiler Partners was founded in Vienna in 2014 by Gerold Zeiler, the former head of the arbitration practice at another GAR 100 firm from Austria, Schönherr. He brought a team with him to the new boutique.

A former president of the Austrian Arbitration Association, Zeiler regularly sits as arbitrator and is a fellow of the Chartered Institute of Arbitrators. He’s joined at the new firm by partners Lisa Beisteiner and Alfred Siwy, who bring years of experience in ICSID and UNCITRAL work.

The practice received a further boost in 2015 with the hire of Christoph Schreuer as of counsel. Known to some as “Mr ICSID”, he’s the author of the definitive commentary on the ICSID Convention. Another recent addition to the partnership is Markus Schifferl, who joined from Torggler.

The firm’s lawyers have advised high-profile names from several industries, including Shell, RWE, Siemens, GE Capital, Thales, Deutsche Bank, and car companies Fiat and Seat.

Nearly two years in, the firm already has four investment treaty cases on its books. Siwy is defending the Czech Republic in three cases under SCC and UNCITRAL rules; while Zeiler and Siwy are acting for Bosnia-Herzegovina in a €700 million ICSID case brought by a Slovenian investor.

Zeiler and Siwy are also acting for Shell in an ICC gas transport dispute, while other work includes cases for a Swedish furniture producer and a German and French energy client in the gas storage market.
