The only question for determination under plaintiffs’ statutory cause of action for unlawful eviction was as to whether defendant, having “lawfully [gained] possession from a tenant * * * thereafter [failed] fully to comply with such requirements or conditions as may have been imposed for such possession by the provisions of this Act or any regulation, order, or requirement thereunder”. And, the only such “requirement” or “condition”, with which plaintiffs assert that defendant failed fully to comply, was the “condition” in the certificate that eviction was authorized “solely for the purpose of altering and remodeling to such an extent that a tenant could not remain in occupancy while the work was being done.” Therefore, this case turns upon the sole and narrow issue as to whether or not the dwelling in question was altered and remodeled “to such an extent that a tenant could not remain in occupancy while the work was being done.” In urging that they made a submissible case on this issue, plaintiffs assert, among other things, that we should consider (a) “only those repairs * * * which were contemplated by defendant at the time she filed her petition” (apparently meaning only those items specifically listed in her petition, for defendant testified that, when the petition was filed, she “planned” to make all of the additional repairs later made), (b) “by way of background”, conversations between the parties and alleged attempts to evict plaintiffs prior to issuance of the certificate, and (c) that plaintiffs “would have been willing to remain in the house while repairs were taking place.”
