Per Curiam.
We find that there was unreasonable delay as a matter of law in the Office of Rent Control's refusal, for a period of over 15 months, to process the landlords' applications *942 for electrical exclusion decrease orders. It is offensive to one's sense of fairness for these landlords, having timely filed the necessary applications and engaged in a completely proper course of conduct under the pre-existing regulation, to be denied the benefit of the regulation then extant. Under the facts of these cases, the petitioners were entitled to reasonably prompt processing of their applications. The agency's arbitrary decision to impose a moratorium on applications of this nature until it had prepared and promulgated a new regulation should not work to the detriment of these petitioners (see Matter of Pokoik v Silsdorf, 40 N.Y.2d 769, 773; Matter of Parkchester Apts. Co. v Lefkowitz, 51 AD2d 277, 281, affd 41 N.Y.2d 987). Even in the absence of bad faith, administrative procrastination of this magnitude, be it negligent or willful, without excuse or justification, affords a basis for applying the pre-existing regulation to the applications (see Matter of Our Lady of Good Counsel R. C. Church & School v Ball, 45 AD2d 66, affd 38 N.Y.2d 780; cf. 1 Anderson, NY Zoning Law and Practice, § 6.17, p 196).
Accordingly, in each of these cases the order of the Appellate Division should be reversed.
In each case: Order reversed, with costs, and the judgment of Supreme Court, New York County, reinstated.
