I probably would have stumbled across it eventually, but I found it by way of JT.
CPLR R. 4518 Business records
Yellow Book of N.Y., L.P. v Cataldo, 2011 NY Slip Op 00678 (App. Div., 2nd 2010)
Cataldo's contention that the Supreme Court erred in denying his request to exclude a witness from the courtroom is without merit. The record supports the Supreme Court's determination that the witness at issue was employed by the plaintiff's successor-in-interest and was, therefore, a party representative. As such, and in the absence of extenuating circumstances, the witness was entitled to remain in the courtroom throughout the trial (see Auger v State of New York, 263 AD2d 929, 932; Liquori v Barrow, 160 AD2d 843, 844; Carlisle v County of Nassau, 64 AD2d 15, 18). Further, Cataldo failed to establish that he suffered any prejudice due to the continued presence of the witness (see People v Scheck, 24 AD3d 574).
Additionally, Cataldo contends that the plaintiff's documents should not have been admitted into evidence pursuant to the business records exception to the hearsay rule because the plaintiff's witness was employed by the plaintiff's successor-in-interest and because she lacked personal knowledge of the information contained in the documents. As the witness at issue was fully familiar with the plaintiff's record-keeping procedures and practices, this contention is without merit (see CPLR 4518[a]; General Bank v Mark II Imports, 290 AD2d 240, 241). Cataldo's remaining contentions regarding the court's evidentiary rulings are unpreserved for appellate review.
The bold is mine.
