An attorney violates § 487(1) by intentionally deceiving the court or any party. A claim premised on a statutory violation must be supported by a showing that the attorney intended to deceive, or engaged in a chronic and extreme pattern of legal delinquency. In order to make a prima facie showing of entitlement to summary judgment, an affidavit from someone with actual knowledge of the allegations is sufficient. The defendant is not required to submit an affidavit from a legal expert.
