¶1Memorandum. In the procedural posture in which this proceeding comes to us we review questions of law only (CPLR 5501, subd [b]). Petitioners did not sustain their burden of proving the invalidity of the petition, either by proof of permeating fraud or of such other irregularities as to nullify it. The order of the Appellate Division should be affirmed.
¶2Chief Judge Breitel and Judges Jasen, Gabrielli, Jones, Wachtler, Fuchsberg and Cooke concur.
¶3Order affirmed, without costs, in a memorandum.
