The plaintiff's contention that leave to amend was properly denied because the defendant waived the defense of lack of standing by failing to assert that defense in its answer or in a pre-answer motion to dismiss the complaint is without merit. A waiver that results from a failure to affirmatively plead a defense in accordance with CPLR 3018(b), including a waiver of the defense of standing, may be retracted through subsequent amendment to the pleadings.
