There is no basis for dismissal of the appeal; under the circumstances, it is not moot and the relief sought is not barred. Supreme Court properly exercised its discretion, based on its realistic appreciation of the nonparty's interlocking relationship with plaintiff, in finding that the communications between plaintiff and the nonparty were subject to the attorney-client common interest privilege. This was properly based on the special referee's finding of their common legal interest ( see In re Megan-Racine Assoc., Inc., 189 BR 562, 570 [ND NY 1995]), even with respect to prebankruptcy communications ( see generally United States v. Schwimmer, 892 F2d 237, 244 [2d Cir 1989]), despite the fact that they were debtor and creditor.
We have considered defendant's other contentions and find them unavailing.
