Supreme Court, New York County  Docket Number: 152783/2017 she deftly describes the reach of Judiciary Law § 487 in the first department:

“An attorney may be civilly liable for treble damages to an injured party for a violation of Judiciary Law §487 if the attorney is found to be “guilty of any deceit or collusion, or consents to any deceit or collusion, with intent to deceive the court or any party.” Judiciary Law §487(1).
