3.The commission may from time to time to effectuate the purposes of this act adopt, promulgate, amend or rescind such rules, regulations or orders as it may deem necessary or proper for the control of evictions. It may require that an order granting a certificate of eviction be obtained from it prior to the institution of any action or proceeding for the recovery of possession of any housing accommodation subject to a maximum rent under this act upon the grounds specified in subdivision two of this section or where it finds that the requested removal or eviction is not inconsistent with the purposes of this act and would not be likely to result in the circumvention or evasion thereof; provided, however, that no such order shall be required in any action or proceeding brought pursuant to the provisions of subdivision one of this section. The commission on its own initiative or on application of a tenant may revoke or cancel an order granting such certificate of eviction at any time prior to the execution of a warrant in a summary proceeding to recover possession of real property by a court whenever it finds that:
(a) the certificate of eviction was obtained by fraud or illegality; or(b) the landlord's intentions or circumstances have so changed that the premises, possession of which is sought, will not be used for the purpose specified in the certificate. The commencement of a proceeding by the commission to revoke or cancel an order granting a certificate of eviction shall stay such order until the final determination of the proceeding regardless of whether the waiting period in the order has already expired. In the event the commission cancels or revokes such an order, the court having jurisdiction of any summary proceeding instituted in such case shall take appropriate action to dismiss the application for removal of the tenant from the real property and to vacate and annul any final order or warrant granted or issued by the court in the matter.
