Motion granted and appeal dismissed, without costs, to the extent that review is sought of the final order of the Appellate Division, entered December 23, 1974, upon the ground that that order is not separately reviewable as of right, absent a substantial constitutional question. Upon the appeal pursuant to CPLR 5601 (subd [d]), only the prior nonfinal order of the Appellate Division may be reviewed. (NY Const., art VI, § 3, subd b, par [1]; CPLR 5501, subd [b]; 5601, subds [b], [d].)
