Appeal by defendant-intervenor from an amended judgment ¡of the Supreme .Court, entered February 28, 1969 in Rensselaer ¡County upon a decision of the court at Special Term, which approved a plan of reapportionment of the Board of Supervisors of Rensselaer County, as approved and submitted by the board in accordance with the prior direction of the court, made upon holding the existing apportionment constitutionally invalid. The .total population affected is 138,666. Ideally, the 15 districts1 contemplated by the approved plan would ¡contain a population of 9,244 each. The largest district projected is of 10,843, however, and the smallest is of 8,052; a population differential of 2,791 being thereby created; and the ratio between the largest district and the smallest ¡thus being 1.346 to 1. Absent acceptable explanation, such a variance would not ¡ordinarily be approved. ('See Davis v. Board of ¡Supervisors of County of Clinton•, 28 A D 2d 583, citing Swann v. Adams, 385 U. IS. 440.) We note, however, the imminence of the spring primary election, the first day for signing designating petitions being but three weeks away; we give consideration to the probability that the 1970 census figures will be available during the life of the board to be elected in 1969; and we consider, further, that, if ¡employed as a temporary measure, the plan before us, having been adopted by the representative body, is preferable, generally and despite some measure of infirmity, to a plan to be fashioned by the court, as would otherwise he necessary in this case, by reason of the present time exigencies. In reaching this conclusion we have considered and rejected the alternate plans presented, including that which provided for weighted voting. That plan, approved by the hoard as one of three alternatives, was properly rejected by Special Term inasmuch as it was demonstrated by computer analysis that the disparity of effective voting power and the actual percentage of population between .districts was excessive, that between proposed districts 1 and 20, for example, being in excess of 7%. (See lannueci V. Board of Supervisors of County of Washington, 20 N ¡Y 2d 244, 252; Town of Greenburgh v. Board of Supervisors of County of Westchester, 57 Mise 2d 1008, 1011; Dobish v. State of New York, 54 Mise 2d 367, 371.) We stress our holding that the plan is approved by this court ¡as a temporary ¡and interim measure, to govern the 1969 elections and to continue thereafter until validly superseded (see Matter of Orans, 17 N Y 2d 107, 110); and that the legislative authority must proceed as promptly as circumstances permit to formulate a plan more closely approaching equal representation. Judgment modified, ¡on the law and the facts, in accordance with this memorandum decision and, as so modified, affirmed, without costs. Gibson, P. J., Reynolds, Aulisi, Staley, Jr., and Cooke, JJ., concur in memorandum Per Curiam.
