OPINION OF THE COURT
We are asked to interpret recently enacted RPAPL 753 (subd 4) (L 1982, ch 870). The section applies to holdover tenants in residential dwellings in New York City and the new subdivision 4 provides: “In the event that such proceeding [a summary proceeding to recover possession] is based upon a claim that the tenant or lessee has breached a provision of the lease, the [Civil] court shall grant a ten day stay of the issuance of the warrant [to remove], during *23 which time the respondent [tenant] may correct such breach.” The question arises in an appeal from an order of Special Term of Supreme Court granting plaintiff tenant a preliminary injunction in a declaratory judgment action and denying defendant’s cross motion to dismiss the complaint.
Plaintiff, a psychiatrist, is a residential tenant pursuant to a proprietary lease in a building owned by defendant at 120 East End Avenue. Several years ago, he was required to vacate his private office and he began to schedule patients’ visits either at his office at Columbia University Medical School, where he is an associate professor, or at his 14-room apartment in defendant’s building. In June, 1981, defendant sent a notice to plaintiff stating that use of the premises for professional purposes without its consent violated terms of the lease which required that the apartment be used only as a private dwelling. It demanded that plaintiff discontinue seeing patients in the apartment immediately. There followed correspondence and conferences at which plaintiff admitted using his apartment to see patients intermittently, but stated that he was actively seeking office space. The situation did not change and on December 9, 1981, defendant again formally demanded that plaintiff stop seeing patients in the apartment. Finally, on February 23, 1982, defendant served a notice on plaintiff declaring that he was in violation of the residential covenants of the lease and that if he did not cure the violation by March 26,1982, his lease would be terminated as provided by its terms. Before the time to cure expired, plaintiff instituted this Supreme Court action seeking a declaration of his rights and an order permanently enjoining defendant from interfering with his right to quiet enjoyment. He pleaded four causes of action alleging (1) that he had not breached the terms of the lease, (2) that any default was not material, (3) that defendant was estopped from enforcing the requirements of residential use only and (4) that defendant had waived the default. These claims present disputed issues of facts.
On March 15,1982, plaintiff obtained a show cause order from Supreme Court which contained a temporary restraining order. Defendant served a cross motion, return *24 able on the same day, seeking dismissal of plaintiff’s complaint. On September 30,1982, the court denied defendant’s cross motion and granted plaintiff a Yellowstone preliminary injunction staying further proceedings by defendant until determination of the parties’ claims at trial.
Subsequent to the submission to Special Term, but before its order was executed, the Legislature amended RPAPL 753 by adding the new subdivision 4, effective July 29, 1982. The parties did not submit the application of the new subdivision to Special Term because it became effective after argument of the motion and defendant did not move for reargument. The Appellate Division affirmed the order and granted leave to appeal on a certified question (
We agree that the new statute should be considered in the determination of this appeal. It is procedural and remedial in nature and it should be liberally construed to spread its beneficial effects as widely as possible. More importantly the statute will apply in any subsequent Civil Court proceedings, should this complaint be dismissed (see
Klausner v Frank,
Yellowstone
injunctions became commonplace following our decision in
First Nat. Stores v Yellowstone Shopping Center
(
RPAPL 753 (subd 4) provides that in a summary proceeding in Civil Court the court shall, after adjudicating the merits, grant a losing tenant a 10-day period within which to cure the default. In effect it gives the losing tenant what he would receive with a
Yellowstone
injunction in a Supreme Court action after losing, a period of time to cure the violation before being subject to removal. Thus defendant contends that the statute provides full protection to tenants, eliminating any possibility that a satisfactory preliminary showing can be made that the equities of the situation warrant injunctive relief (see, e.g.,
Klausner v Frank,
There is, however, one notable distinction between the
Yellowstone
remedy and the statutory remedy. A
Yellowstone
injunction prevents expiration of the lease by tolling the running of the cure period, a necessary precondition to terminating the lease; the statute does not do so by its terms. Thus before Civil Court can acquire jurisdiction the lease has expired and, under the ruling of
Yellowstone,
it cannot be revived. Troubled by this conceptual problem, unresolved by the language of the amendment, some courts have been reluctant to deny Supreme Court jurisdiction to grant injunctive relief (see, e.g.,
Wilen v Harridge House Assoc.,
*27
Notwithstanding these problems, the interpretation urged by defendant appears to be precisely what the Legislature intended. The sponsor’s stated purpose for the bill was to permit tenants to remain in possession by curing the violation after the rights of the parties have been adjudicated.

Notably, the amendment provides not only for a mandatory stay of removal but also provides that the tenant shall have an opportunity to cure. Although it makes no provision for reviving the lease, this omission was not unanticipated. The correspondence in the Governor’s bill jacket indicates that the legislation was opposed by some objectors for just this reason (see Letter of Counsel for New York State Builders Association, Inc., dated July 19, 1982). Moreover, if the legislation was not intended to authorize the continuation of the lease, the amendment was unnecessary because existing BPAPL 753 (subd 1) grants Civil Court the discretion to stay removal proceedings while the tenant relocates, not for just 10 days, but for six months. Unless the Legislature intended the tenancy to continue the amendment is surplusage. Thus, although the lease may contain a conditional limitation which permits it to be terminated if the tenant fails to cure, we interpret the statute as impressing its terms on residential leases and, in effect, authorizing Civil Court at the conclusion of summary proceedings to impose a permanent injunction in favor of the tenant barring forfeiture of the lease for the violation in dispute if the tenant cures within 10 days. Under this interpretation the statute would necessarily protect against any other losses incident to forfeiture, including in this case, the loss of plaintiff’s stock in the cooperative which could result from the termination of his lease. To this extent the statute limits our holding in
First Nat. Stores v Yellowstone Shopping Center
(
*28
There are sound policy reasons for interpreting the statute in this way. Civil Court has jurisdiction of landlord tenant disputes (see CCA 204) and when it can decide the dispute, as in this case, it is desirable that it do so
(Lun Far Co. v Aylesbury Assoc.,
The rationale of our decision necessarily presumes that Civil Court can grant full relief and that the tenant will be unable to make the necessary showing to invoke the equitable powers of Supreme Court. If the tenant is unable to obtain complete relief in Civil Court, then the jurisdiction of Supreme Court is still available (see
Wilen v Harridge House Assoc.,
Plaintiff objects to the amendment being considered for the first time by the Appellate Division. It is settled law, however, that a court applies the law as it exists at the time of appeal, not as it existed at the time of the original

Notes
The Memorandum of Senator Leon Bogues was as follows: “Real Property Actions and Proceedings Law: § 753. This bill provides for a ten day stay before the court shall issue a warrant upon a claim that the tenant or lessee has breached a provision of the lease. The cause of the breach may, for various reasons, be temporary in nature correctable within the ten day period. This bill which deals only with residential tenants will allow a cure of a breach of the lease after a determination is made that a breach actually exists. Many tenants have the reasonable expectation that they will have an opportunity to cure once they have been advised by the court that, in fact, they have breached the lease provision. Under existing law, there is no such opportunity.” (NY Legis Ann, 1982, p 280.)
