§ 796-m. Defense of warranty of habitability inapplicable. Notwithstanding any other provision of law, in any proceeding for the payment of rent commenced by an administrator appointed pursuant to this article, the provisions of § 235-b of the real property law pertaining to the warranty of habitability shall not be a defense to such a proceeding for rent which accrues during the period of time that a judgment or an order pursuant to this article is in effect, unless the court determines that the conditions upon which such defense is based were caused by the failure of such administrator to perform his or her duties in a reasonable manner.
