Orrick, Herrington & Sutcliffe has hired former Weil, Gotshal & Manges partner Eric Hochstadt as head of its antitrust litigation practice and a member of the management committee.

Hochstadt, who joined the firm Thursday, was previously at Weil for more than 21 years. He said he was motivated to change firms because the new role “presented a great special opportunity to build and lead antitrust and to lead across their entire sector-focused platform by joining the management committee.”
