The certificate, by virtue of which ■defendant “lawfully [gained] possession” of the premises, did not refer to defendant’s petition, did not state or disclose whether or not the findings of the Area Rent Director were predicated upon defendant’s petition, other statements, or independent investigation by the Director or his staff, and was not conditioned upon removal of the partition between the living room and dining room or, for that matter, upon the doing of any specified or described work. If the premises in question actually were altered and remodeled “to such an extent that a tenant could not remain in occupancy while the work was being done,” the authorized purpose for eviction was satisfied and fulfilled and there was' no breach of the “condition” in the certificate. We reject plaintiffs’ contention that we should consider only those repairs and alterations specifically listed and described in defendant’s petition.
