I.R., et al. v. Santos, et al.
Attorneys and Parties
Brief Summary
Personal injury—whether a unified trial (liability and damages tried together) is warranted where the nature and extent of injuries bear directly on how the accident occurred.
Denied plaintiffs' motion for a unified trial and, by implication, required a bifurcated trial.
The denial of a unified trial; the Appellate Division reversed and granted a unified trial on liability and damages.
Because the parties offered conflicting accounts of how the injury occurred, and evidence about the nature and extent of the infant plaintiff’s injuries was probative of causation and mechanism of injury, thereby bearing directly on liability; the trial court improvidently exercised its discretion in denying unification.
Background
On May 16, 2020, the infant plaintiff allegedly suffered a right foot injury when it was run over by a van owned by Jacinto Santos and operated by Wilber Gonzalez. Gonzalez disputed this, testifying the van was not in operation and that the infant fell from a bicycle. After discovery, plaintiffs moved for a unified trial, arguing that medical evidence about the nature and extent of the injuries would help determine whether the injuries were caused by a van running over the foot or a bicycle fall.
Lower Court Decision
In an order dated June 20, 2024 (Supreme Court, Suffolk County, Whelan, J.), the court denied plaintiffs’ motion for a unified trial on liability and damages.
Appellate Division Reversal
The Appellate Division reversed, holding that the nature of the injuries had an important bearing on liability given the competing narratives of how the accident occurred. Citing established precedent encouraging bifurcation only where appropriate, and assigning the burden to the party opposing unification to show the injuries necessarily aid the liability determination, the court concluded the Supreme Court improvidently exercised its discretion. The motion for a unified trial was granted.
Legal Significance
Reaffirms in the Second Department that unified trials are appropriate when the injury evidence is integral to determining liability—such as where it helps resolve disputed mechanisms of injury. While bifurcation is encouraged in suitable cases, trial courts must exercise discretion in light of case-specific facts; denying unification can be an abuse of discretion when injury evidence is directly probative of liability.
If the mechanism of injury is disputed and medical evidence of the injuries will materially aid the factfinder on liability, a unified trial should be ordered.
