Harris v Campbell, 2017 NY Slip Op 08112 (4th Dept. 2017)

(1) CPLR 3101(d)

“Contrary to plaintiffs’ contention, the court properly limited the testimony of one of plaintiff’s treating physicians. “CPLR 3101 (d) (1) applies only to experts retained to give opinion testimony at trial, and not to treating physicians, other medical providers, or other fact witnesses” (Rook v 60 Key Ctr., 239 AD2d 926, 927 ). ” Where … a plaintiff’s intended expert medical witness is a treating physician whose records and reports have been fully disclosed … , a failure to serve a CPLR 3101 (d) notice regarding that doctor does not warrant preclusion of that expert’s testimony on causation, since the defendant has sufficient notice of the proposed testimony to negate any claim of surprise or prejudice’ ” (Hamer v City of New York, 106 AD3d 504, 509 ). Here, one of plaintiff’s treating physicians did not provide any expert disclosure, and during trial he indicated that, in addition to being a medical doctor, he received a Ph.D. in biomechanical engineering and he often relies on his engineering background in his medical practice. Subsequently, that treating physician was asked some questions pertaining to biomechanics, and specifically was asked about the amount of force needed to cause a lumbar injury. We conclude that defendant’s objections to that line of questioning were properly sustained inasmuch as defendant did not receive sufficient notice that the treating physician relied on his engineering background to support his opinions and conclusions about plaintiff’s injuries (see generally id.). Indeed, plaintiffs made no attempt in response to defendant’s objections to point to any medical records or other documentation that would establish that defendant had such notice.”

(2) “We reject plaintiffs’ contention with respect to the photographs of plaintiff’s vehicle inasmuch as it is well established that “hotographs showing no damage to a plaintiff’s vehicle are admissible to impeach a plaintiff’s credibility on the issue whether the accident caused the alleged injuries” (Tout v Zsiros, 49 AD3d 1296, 1297 , lv denied 10 NY3d 713 ). Furthermore, “even when liability is not at issue, proof as to the happening of an accident is probative and admissible as it describes the force of an impact or other incident that would help in determining the nature or extent of injuries and thus relate to the question of damages’ ” (Anderson v Dainack, 39 AD3d 1065, 1066 )”

Legal Context

Why This Matters for Your Case

New York law is among the most complex and nuanced in the country, with distinct procedural rules, substantive doctrines, and court systems that differ significantly from other jurisdictions. The Civil Practice Law and Rules (CPLR) governs every stage of civil litigation, from service of process through trial and appeal. The Appellate Division, Appellate Term, and Court of Appeals create a rich and ever-evolving body of case law that practitioners must follow.

Attorney Jason Tenenbaum has practiced across these areas for over 24 years, writing more than 1,000 appellate briefs and publishing over 2,353 legal articles that attorneys and clients rely on for guidance. The analysis in this article reflects real courtroom experience — from motion practice in Civil Court and Supreme Court to oral arguments before the Appellate Division — and a deep understanding of how New York courts actually apply the law in practice.

New York law varies by jurisdiction — court decisions in one Appellate Division department may not be followed in another, and local court rules in Nassau County Supreme Court differ from those in Suffolk County Supreme Court, Kings County Civil Court, or Queens County Supreme Court. The Appellate Division, Second Department (which covers Long Island, Brooklyn, Queens, and Staten Island) and the Appellate Term (which hears appeals from lower courts) each have distinct procedural requirements and precedents that affect litigation strategy.
