Given the established body of case law that exists, it is hard to believe that the New York Pattern Jury instructions (PJI) does not provide for a specific charge to the jury in lost chance cases. See Alan Clark, "Lost Chance as Substantial Factor in Causing Injury," NYLJ (Part 1: Oct. 14, 2020 and Part 2: Oct. 21, 2020. Although the 2020 commentary to the medical malpractice charge PJI 2:150 does discuss at length loss of chance (see pages 81-85) the proximate cause charge PJI 2:70 does not. As experienced counsel know the proximate cause charge is brief and amazingly the commentary does not address this subject matter.
