Orrick Herrington & Sutcliffe and Cleary Gottlieb Steen & Hamilton are facing malpractice claims over an alleged one-word defect in an acquisition contract. Both firms say the claims lack merit.

Kasowitz Benson Torres, on behalf of clients TerraForm Power Parent and TerraForm Power LLC, brought the suit against Orrick and Cleary in New York Supreme Court. The allegations relate to a 2014 contract regarding the sale of certain assets by First Wind Holdings.
