Section 783. 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 section two hundred thirty-five-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
  duties in a reasonable manner.
