N.Y. Priv. Hous. Fin. Law § 213
Whenever a redevelopment corporation shall not have obtained the certificates of approval of its development plan required by section two hundred three of this article within twelve months of the date upon which it became a redevelopment corporation, or shall not have substantially complied with its development plan within the time limits for the completion of each stage thereof as therein stated, reasonable delays caused by unforeseen difficulties excepted, or shall do, permit to be done or fail or omit to do anything contrary to or required of it, as the case may be, by this article, or shall be about so to do, permit to be done or fail or omit to have done, as the case may be, then any such fact may be certified by the planning commission or the supervising agency, whichever shall have supervision thereof, to the chief legal officer of the city, who may thereupon commence a proceeding in the supreme court of the state of New York in its name for the purpose of having such action, failure or omission, or threatened action, failure or omission, established by order of the court for the purpose stated in subdivision two of section two hundred five of this article, or stopped, prevented or otherwise rectified by order, injunction or otherwise. Such proceeding shall be commenced by a petition to the supreme court alleging the violation complained of and praying for appropriate relief. It shall thereupon be the duty of the court to specify the time, not exceeding twenty days after service of a copy of the petition, within which the redevelopment corporation complained of must answer the petition. The court shall, immediately after a default in answering or after answer, as the case may be, inquire into the facts and circumstances in such manner as the court shall direct without other or formal proceedings, and without respect to any technical requirements. Such other persons or corporations as it shall seem to the court necessary or proper to join as parties in order to make its order or judgment effective may be joined as parties. The final judgment or order in any such action or proceeding shall dismiss the action or proceeding or establish the failure complained of or direct that an order, or an injunction, or both, issue, or grant such other relief as the court may deem appropriate.
