Two Second Department decisions issued on April 3, 2019, show different outcomes on causation evidence. Torres v Rettaliata, 171 AD3d 829, allowed the case to continue. Campanile v Miller, 171 AD3d 690, affirmed dismissal. Both decisions turned on the medical proof submitted on the motion.

Legal Update (September 2026): Chapter 58 of 2026, Part EE §§ 1 and 4 removed the 90/180-day serious-injury category for actions and proceedings commenced on or after May 26, 2026. This historical case predates that amendment.

Torres: severity and causation required separate analysis

The defendants made an initial showing that the right-shoulder and spinal injuries did not meet the permanent-consequential or significant-limitation categories. The plaintiff then raised a factual dispute about those categories.

On causation, however, the defendants failed to establish that the injuries were unrelated to the accident. The burden therefore did not shift to the plaintiff to answer a lack-of-causation showing or explain a treatment gap. The court affirmed denial of the defense motion. It did not hold that the defense had failed every part of its initial burden.

Campanile: the radiologist’s findings went unanswered

The defendant submitted medical evidence that the cervical and lumbar conditions were not caused by the accident. His radiologist identified degenerative changes on MRIs taken about a month after the collision. The plaintiff’s experts did not address those findings, so their opposition did not raise a triable causation issue.

Read together, these opinions require attention to the actual motion record. An opponent does not have to cure a showing the movant never made. Once a supported degeneration argument is made, a general statement attributing injuries to the accident may not answer it. These were serious-injury motions, not trial findings establishing a universal medical checklist or a fixed treatment-gap deadline.

Frequently Asked Questions

What happens if defendants fail to establish prima facie lack of causation?

In Torres, no causation or treatment-gap burden shifted because the defendants did not establish lack of causation. The plaintiff still had to answer the separate showing about injury severity and did so.

Can degenerative conditions completely bar recovery in personal injury cases?

Not automatically. Campanile was dismissed because the plaintiff’s experts did not answer supported findings of degeneration; Torres reached a different result on a different motion record.

How long can treatment gaps be before they affect causation?

These decisions do not set a fixed number of days or months. First identify whether the movant established the relevant causation defense, then examine the treatment history and any explanation required on that record.

What standard must expert testimony meet regarding causation?

An opinion must have an evidentiary basis and answer the issue actually raised. Campanile illustrates why a general causal attribution may fail when it leaves specific radiological findings unaddressed.

Can multiple causes affect the causation analysis?

More than one explanation may require medical analysis, but these decisions do not prescribe a universal apportionment formula. The motion must be assessed on the evidence offered for the claimed accident-related injury.

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.

About This Topic

Causation in New York Personal Injury & No-Fault Law

Causation — proving that the defendant's negligence or the accident caused the plaintiff's injuries — is an essential element of every personal injury and no-fault claim. New York courts distinguish between proximate cause, intervening causes, and pre-existing conditions that may have been aggravated by an accident. The legal standards for establishing causation through medical evidence and the defenses available to challenge causal connection are analyzed in depth across these articles.

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.
