Familiar theme on experts and 2106

The interplay between expert witness qualifications and technical compliance with CPLR 2106 continues to generate significant litigation in New York courts. While substantive expertise remains paramount, procedural defects in expert affirmations can derail otherwise meritorious cases. The First Department’s decision in Lopez v Gramuglia provides critical guidance on both dimensions: the breadth of permissible expert testimony across medical specialties and the preservation requirements for challenging expert qualifications under CPLR 2106.

New York’s approach to expert witness qualifications reflects a practical recognition that modern medicine involves overlapping knowledge domains. The Court of Appeals established in Fuller v Preis that medical experts need not practice in the exact specialty at issue to offer competent testimony about standards of care. This principle acknowledges that physicians receive broad training during medical school and residency, often gaining sufficient familiarity with related fields to render informed opinions. An orthopedic surgeon, for instance, regularly encounters podiatric issues in clinical practice, making cross-specialty testimony both logical and reliable.

However, this liberal approach to substantive qualifications contrasts sharply with the stringent procedural requirements governing expert affirmations. CPLR 2106 mandates that affirmations from physicians explicitly state they are “duly licensed” to practice medicine. This seemingly technical requirement serves an important gatekeeping function, ensuring that only properly credentialed professionals offer expert opinions in legal proceedings. Courts have consistently held that substantial compliance is insufficient; the statute demands precise language affirming licensure status.

Case Background

Lopez v Gramuglia arose from a podiatric malpractice claim where the defendant orthopedic surgeon submitted an expert affirmation from Dr. Robbins, also an orthopedist. The plaintiff challenged the affirmation on two grounds: first, that an orthopedist lacked qualification to opine on podiatric standards of care; and second, that Dr. Robbins’ affirmation failed to satisfy CPLR 2106’s licensure statement requirement. Dr. Robbins’ credentials were impressive, including board certification in orthopedic surgery, graduation from Columbia University College of Physicians and Surgeons, and completion of a New York City residency. Yet his affirmation recited these qualifications without explicitly stating he was “duly licensed” as a physician in New York.

The motion court accepted Dr. Robbins’ affirmation and granted summary judgment to the defendant. On appeal, the plaintiff renewed both challenges, arguing that orthopedists cannot competently evaluate podiatric care and that the CPLR 2106 defect warranted exclusion of the expert’s opinion. The First Department’s resolution of these issues reinforces established precedent while highlighting the critical importance of preserving objections at the trial level.

Familiar lesson here. An expert can generally opine about all areas of medicine. The other lesson here is that a 2106 objection needs to be specific.

“At the outset, defendant’s expert affirmation was properly considered. Dr. Robbins, an orthopedist, was qualified to render an opinion as to the standard of care in podiatry, since a medical expert need not be a specialist in a particular field in order to testify regarding accepted practices in that field (see Fuller v Preis, 35 NY2d 425, 431-433 ; and see Limmer v Rosenfeld, 92 AD3d 609 ). Although, Dr. Robbins’ affirmation, which recited his credentials as including, inter alia, board certification as an orthopedic surgeon, and graduation from Columbia University College of Physicians and Surgeons, with the completion of a residency in New York City, did not specifically state that he was a “duly licensed physician,” or that he was “duly licensed in the State of New York” (see e.g. CPLR 2106), plaintiff failed to raise this argument before the motion court and, as such, it is unpreserved for appellate review (see Shinn v Catanzaro, 1 AD3d 195, 197-198 ; see also Scudera v Mahbubur, 299 AD2d 535 ).”

Legal Significance

The First Department’s decision reinforces two fundamental principles governing expert testimony in New York medical malpractice litigation. First, courts apply a functional approach to expert qualifications, focusing on whether the witness possesses sufficient knowledge and experience to offer reliable opinions rather than demanding precise specialty matching. This approach reflects the reality that medical knowledge often transcends specialty boundaries, particularly in fields with substantial overlap like orthopedics and podiatry.

Second, the preservation doctrine operates strictly in this context. Even clear procedural violations of CPLR 2106 become unreviewable if not raised before the motion court. This rule serves important policy objectives: it prevents parties from sandbagging opponents by withholding objections until appeal, ensures trial courts have the opportunity to address issues in the first instance, and promotes judicial efficiency by resolving evidentiary disputes early in litigation.

The decision also illustrates the tension between substance and form in expert witness requirements. While Dr. Robbins clearly possessed the qualifications necessary to offer expert testimony, the technical defect in his affirmation could have proven fatal had the plaintiff timely objected. This disparity between substantive competence and procedural compliance underscores the importance of meticulous attention to CPLR 2106’s requirements when preparing expert submissions.

Practical Implications

For practitioners defending medical malpractice claims, Lopez v Gramuglia offers both reassurance and caution. Defense counsel can confidently rely on experts from related specialties, knowing that New York courts will not impose artificial barriers to cross-specialty testimony. An orthopedist evaluating podiatric care, a cardiologist reviewing internist treatment, or a general surgeon assessing specialized surgical procedures may all offer admissible opinions under Fuller v Preis.

However, Lopez simultaneously demonstrates that even substantively qualified experts face exclusion for procedural defects if opponents timely object. Defense attorneys must ensure expert affirmations explicitly state the affiant is “duly licensed” to practice medicine in New York, regardless of how extensively the affirmation recites other credentials. Boilerplate language satisfying CPLR 2106 should appear in every expert affirmation as standard practice.

Plaintiff’s counsel must remain vigilant about CPLR 2106 compliance and raise objections promptly before the motion court. Appellate courts will not excuse failures to preserve such challenges, even when the procedural violation appears obvious from the face of the expert’s affirmation. The narrow window for objecting requires careful review of all expert submissions immediately upon receipt and timely assertion of defects in opposition papers or pre-motion correspondence.
