8 N.Y.3d 515 (2007)
Expert testimony, when offered as the sole evidence to establish an industry standard or practice, must be supported by a factual basis and cannot be speculative or conclusory to withstand summary judgment.
Summary
Tenebaum sued New York Downtown Hospital for negligent supervision after being sexually assaulted by a male technician during a transvaginal sonogram. Tenebaum argued that the hospital was negligent for not having a policy requiring a female staff member to be present during the procedure. Her case relied heavily on expert testimony citing guidelines from radiological organizations recommending a female presence. The New York Court of Appeals held that the expert’s affirmation, lacking a factual basis for concluding that these guidelines reflected an accepted industry standard, was insufficient to defeat the hospital’s motion for summary judgment. This case highlights the importance of providing concrete evidence, beyond mere recommendations, to establish industry standards in negligence claims.
Facts
Tenebaum was sexually assaulted by a male technician while undergoing a transvaginal sonogram at New York Downtown Hospital. The incident occurred when Tenebaum and the technician were alone in the examination room. Tenebaum sued the hospital alleging negligent hiring, training, supervision, and retention of the technician, claiming the hospital should have known the technician was likely to commit such acts. Tenebaum’s case hinged on the argument that the hospital deviated from the standard of care by not having a policy requiring a female staff member’s presence during transvaginal sonograms.
Procedural History
The Supreme Court initially granted the hospital’s motion for summary judgment, dismissing all claims except the negligent supervision claim, finding that the expert affirmation created a factual question. The Appellate Division reversed, dismissing the entire complaint, stating that the guidelines cited by Tenebaum’s expert did not establish an industry standard and lacked evidence of actual practice. The case then went to the New York Court of Appeals following a two-Justice dissent in the Appellate Division.
Issue(s)
Whether an expert’s affirmation, citing professional organization guidelines recommending a practice without providing a factual basis that such guidelines reflect an accepted industry standard, is sufficient to defeat a motion for summary judgment on a negligent supervision claim.
Holding
No, because the expert’s opinion was not supported by sufficient factual evidence to establish that the recommended guidelines constituted a generally accepted standard or practice in hospital settings.
Court’s Reasoning
The Court of Appeals affirmed the Appellate Division’s decision, emphasizing that while expert testimony can preclude summary judgment when it demonstrates a deviation from relevant industry standards, such testimony must be grounded in a factual basis. The court noted that the guidelines from the American College of Radiology explicitly stated that their guidelines “are not rules.” Furthermore, the expert failed to provide evidence that the guidelines were reflective of a generally accepted standard or practice. The court stated, “Where the expert’s ultimate assertions are speculative or unsupported by any evidentiary foundation, however, the opinion should be given no probative force and is insufficient to withstand summary judgment.” Because the expert’s affirmation lacked a concrete basis for its conclusions, it was deemed insufficient to overcome the hospital’s motion for summary judgment. The court required more than just the recommendation of guidelines to establish an industry standard; actual implementation or recognition of the standard within the relevant community was necessary. The absence of reference to personal knowledge or evidence of implementation by other hospitals fatally undermined the expert’s opinion.
