Where you can go wrong on a liability case – an interesting and scary read

By Jason Tenenbaum 8 min read

Key Takeaway

A cautionary tale about how failing to establish basic liability elements can lead to directed verdicts and potential malpractice claims in personal injury cases.

The Fundamentals of Proving Liability in Personal Injury Cases

Establishing a prima facie case in personal injury litigation requires proving specific foundational elements before a jury can even consider damages. One of the most basic requirements is identifying the defendant as the person responsible for causing the accident. This seemingly simple step can make or break an entire case, as demonstrated in a sobering Second Department decision that serves as a stark reminder of what can go catastrophically wrong when attorneys overlook fundamental proof requirements.

The case highlights the critical importance of properly establishing each element of liability during trial. Without adequate proof connecting the defendant to the incident, even the strongest damages case will fail. This principle applies across various contexts, whether dealing with preclusion orders or cases where denials serve as operative documents for establishing prima facie burdens.

Jason Tenenbaum’s Analysis:

Miller v Bah, 2010 NY Slip Op 04753 (2d Dept. 2010)

“After he testified, the plaintiff, who did not identify the defendant in court as the driver of the offending vehicle, rested his case without calling another witness, or offering an accident report into evidence. The defendant, who did not present a case, then moved pursuant to CPLR 4401 for judgment as a matter of law.”

Defendant eventually receives the directed verdict, and a malpractice case may be on its way.

Key Takeaway

This case demonstrates how failing to establish basic identification of the defendant as the driver can result in a complete case dismissal, even when the defendant presents no defense. Proper trial preparation must include ensuring all foundational elements of liability are adequately proven before resting your case. Such fundamental oversights can lead to directed verdicts and potential malpractice exposure.


Legal Update (February 2026): Since this post’s publication in 2010, CPLR provisions and procedural requirements for establishing prima facie cases may have been modified through legislative amendments or evolving case law interpretations. Practitioners should verify current CPLR 4401 standards and recent appellate decisions regarding burden of proof requirements in personal injury litigation, as identification and liability establishment procedures may have been refined or clarified through subsequent court rulings.
