Co., 58 A.D.3d 513, 871 N.Y.S.2d 129 (1st Dep’t 2009)(reversing order dismissing declaratory judgment action against insurer based on late notice where insured established a good-faith belief of nonliability, excusing the untimely notice, where husband of trip and fall victim told restaurant manager told manager “not to worry” because his wife had tripped over her shoelaces and where couple had disappeared by the time manager returned to parking lot with materials to write an incident report).

Coren, 21 A.D.3d 1045, 803 N.Y.S.2d 629 (2d Dep’t 2005)(holding that  plaintiffs failed to raise a triable issue of fact, as their expert’s affidavit did not mention whether the expert had any specific training or expertise in surgery, gastroenterology, or pediatrics.

Robinson v. Aziz, 275 A.D.2d 362, 364, 712 N.Y.S.2d 585 (2d Dep’t 2000)(medical malpractice:  plaintiff sustained permanent injuries when an anesthesiologist negligently administered general anesthesia during surgery.  Issue was whether anesthesiology practice should be vicariously liable to the patient. The jury found that the attending physician was an independent contractor and not an employee of the practice, but the trial court held that the practice was liable because administration of anesthesiology is an “inherently dangerous activity,” creating a non-delegable duty. Reversing the lower court, setting aside a $700,000 judgment and dismissing the complaint, the Appellate Division agreed with our position about the potential ramifications of this ruling, holding that “[p]ublic policy is not served by applying the inherently dangerous work exception to the practice of accepted medical procedures, as an employer should not be required to anticipate that a medical professional hired as an independent contractor will exercise his or professional judgment in a manner that is dangerous or contraindicated.”)

Saxe v. Veber, 86 N.Y.2d 820, 657 N.E.2d 492, 633 N.Y.S.2d 471 (1995)
(Medical malpractice case in which plaintiff attempted to change the venue of the action on the ground that plaintiff was a sitting judge in the original venue (Manhattan) but to a county which is traditionally friendly to plaintiffs in tort cases (Kings).  Despite the absence of explicit statutory language to this effect, Court of Appeals holds that a change of venue must be to a place where the action could have been venued in the first place, thus preventing the abuse attempted in this case).
