The Webuild case arose in connection with an arbitration between Italian company Webuild and Panama under the Italy-Panama bilateral investment treaty. Webuild obtained an ex parte order from the U.S. District Court for the Southern District of New York permitting it to subpoena evidence from WSP, a non-party located in New York. Upon being served with the subpoena, WSP moved to vacate the order and quash the ensuing subpoena.
