OBJECTIVE MEASUREMENTS ARE NOT NECESSARY TO PROVE A SIDEWALK HEIGHT DIFFERENTIAL DEFECT IS TRIVIAL; HOWEVER, HERE THE DEPOSITION TESTIMONY, THE PHOTOGRAPHS AND THE OPINION OF A HUMAN FACTORS EXPERT (WHICH WAS NOT BASED ON OBJECTIVE MEASUREMENTS) DID NOT SUPPORT SUPREME COURT’S FINDING THE DEFECT IS TRIVIAL AS A MATTER OF LAW (SECOND DEPT).

The Second Department, in a full-fledged opinion by Justice Dillon, reversing Supreme Court’s finding that the sidewalk defect was trivial as a matter of law, determined (1) objective measurements of a sidewalk defect in a slip and fall case are not required for a defendant to make out a prima facie case that the defect is trivial (2) photographs can be examined to determine triviality and (3) the opinion of a human factors expert about a sidewalk elevation differential is inadmissible if it is not based on an objective measurement or a “fairly inferable estimate of the differential:”

In this trip-and-fall case, the defendants moved for summary judgment dismissing the complaint on the ground that the alleged defect on which the injured plaintiff tripped was trivial as a matter of law and, thus, not actionable. In support of their motion, the defendants submitted photographs of the alleged defect, along with other evidence, but they did not submit an objective measurement of the dimensions of the alleged defect. On the plaintiffs’ appeal from the order granting the defendants’ motion, we address three specific questions relating to the trivial defect doctrine: (1) To establish, prima facie, that an alleged sidewalk defect was trivial as a matter of law and, thus, not actionable, must a defendant moving for summary judgment present an objective measurement of the alleged defect’s dimensions? (2) If not, how are courts to examine photographic evidence in order to determine whether the alleged defect is trivial? (3) Is the opinion of a human factors expert conclusory and speculative, and therefore inadmissible, if the opinion is not based upon objective measurements of the defect? For reasons set forth below, we hold that an objective measurement of a defect is not a per se requirement for a party to meet the prima facie burden of proving an entitlement to summary judgment. We use this occasion to discuss how photographs in such instances should be examined to render a determination on triviality. Further, we hold, as an issue of first impression, that the opinion of a human factors expert about an elevation differential is conclusory and inadmissible if it is not based upon an objective measurement or at least a fairly inferable estimate of the differential. * * *

In all, the defendants’ submissions, including the photographs, even when considered in combination with the deposition testimony and other evidence, did not support the Supreme Court’s conclusion of triviality as a matter of law … . Snyder v AFCO Avports Mgt., LLC, 2024 NY Slip Op 04584, Second Dept 9-25-24

​Practice Point: Consult this opinion for guidance on the proof required to find a sidewalk height differential trivial as a matter of law, including the role of objective measurements, interpretation of photographs and the sufficiency of a human-factors expert’s opinion.
