(b) In any such action or proceeding the plaintiff or landlord shall not be entitled to an order or judgment awarding him possession of the premises or providing for removal of the tenant, or to a money judgment against the tenant, on the basis of non-payment of rent for any period during which there was outstanding any violation of law relating to dangerous or hazardous conditions or conditions detrimental to life or health. For the purposes of this paragraph such violation of law shall be deemed to have been removed and no longer outstanding upon the date when the condition constituting a violation was actually corrected, such date to be determined by the court upon satisfactory proof submitted by the plaintiff or landlord.

(c) The defenses provided herein in relation to an action or proceeding against a welfare recipient for non-payment of rent shall apply only with respect to violations reported to the appropriate public welfare department by the appropriate department or agency having jurisdiction over violations. 6. Nothing in this section shall prevent the public welfare department from making provision for payment of the rent which was withheld pursuant to this section upon proof satisfactory to it that the condition constituting a violation was actually corrected. Where rents were reduced by order of the appropriate rent commission, the public welfare department may make provision for payment of the reduced rent in conformity with such order.
