Disqualification of counsel rests in the sound discretion of the court, and here there has been no showing of abuse (see, Schmidt v. Magnetic Head Corp., 101 A.D.2d 268, 277). It cannot be said that the past matters and the instant matter are "completely unrelated" (Macro Cash Carry Corp. v. Berkman, 81 A.D.2d 783, 784).
