Attia v Klebanov, 2021 NY Slip Op 01241 (2d Dpet. 2021)
“Expert opinions, in order not to be considered speculative or conclusory, should address specific assertions made by the movant’s experts, setting forth an explanation of the reasoning and relying on “specifically cited evidence in the record” (Roca v Perel, 51 AD3d 757, 759).”
This is such a basic statement of the law, and I fret it is often forgotten.
