Pascocello v Jibone, 2018 NY Slip Op 03466 (1st Dept. 2018)
“An expert’s opinion “must be based on facts in the record or personally known to the witness” (Hambsch v New York City Tr. Auth., 63 NY2d 723, 725 [1984] [internal quotation marks omitted]; see Roques v Noble, 73 AD3d 204, 206 [1st Dept 2010]), and in the absence of such record support, an expert’s opinion is without probative force (see Diaz v New York Downtown Hosp., 99 NY2d 542, 544 [2002]). Here, Supreme Court properly precluded Dr. Toosi from offering an opinion based on photographs for which no proper foundation had been established.
