Matter of Western Ramapo Sewer Extension Project, 2014 NY Slip Op 05889 (2d Dept. 2014)
“The Supreme Court providently exercised its discretion in precluding two of the Sewer District’s witnesses from testifying at trial as experts, based upon its noncompliance with CPLR 3101(d)(1)(i) (see Rivers v Birnbaum, 102 AD3d 26; Sushchenko v Dyker Emergency Physicians Serv., P.C., 86 AD3d 638, 639; Mohamed v New York City Tr. Auth., 80 AD3d 677, 678; Parlante v Cavallero, 73 AD3d 1001, 1003). In this regard, the Sewer District did not disclose or identify either witness until after the trial had begun, and provided no explanation for that failure.”
Preclusion seems to be waning as to 3101(d) violations unless it occurs after the trial commenced.
