One stipulation may now keep an employee's HR file out of the courtroom in Iowa
Iowa employers just got a powerful new tool to keep messy HR files and past discipline out of negligence trials.
The Iowa Supreme Court ruled on May 22, 2026, that plaintiffs cannot bring a separate negligent hiring, retention, or supervision claim against an employer when there is no dispute that the employee was acting within the scope of employment and the employer is liable for any negligence by that worker.
The unanimous ruling adopts what courts call the preemption rule. It was a question of first impression in Iowa, and the court sided with the position taken by states including California, Colorado, Indiana, Missouri, and Washington, while rejecting the approach in states such as Georgia, Illinois, Kentucky, South Carolina, and Tennessee.
For HR professionals, the practical effect is sharp. Once a company concedes vicarious liability, a plaintiff can no longer run a parallel case picking apart how a worker was hired, retained, or supervised. The court said the second claim becomes redundant, invites prejudicial evidence about a worker's record, and risks double recovery against the same employer.
The case arose from the death of Garrett Baldwin at Iowa Methodist Medical Center. According to the opinion, Baldwin was on continuous dialysis when a nurse on his critical care team fastened the dialysis tubing to his bed rail using a tourniquet or clip that left no slack. When he was repositioned later that day, the catheter pulled from his neck, air entered the line, and he went into cardiac arrest. He died twelve days later. The cause of death is disputed between the parties.
His wife, Rhonda, sued the hospital and the nurse, Andrea Cline. The hospital stipulated to vicarious liability for the negligence of any of its employed nurses who cared for Baldwin, and Cline was dismissed from the case. Rhonda kept a separate claim alive arguing the hospital had been negligent in retaining Cline. The opinion says Cline had been involved in a prior incident, around two years before Baldwin's death, involving the improper placement of a feeding tube that resulted in a patient's death. That earlier estate sued and settled confidentially. The Iowa Board of Nursing formally disciplined Cline in February 2024 for failing to properly assess, document, evaluate, or report on a patient's status. She kept her nursing license.
Writing for a unanimous court, Justice McDonald held that the negligent retention tort is tied to the employee's underlying misconduct. Once an employer admits the worker was on the job and that it is liable for any negligence, the negligent retention claim becomes a second path to the same liability. The court said it is also consistent with Iowa's joint and several liability framework, which treats a vicariously liable employer and the employee as a single unit.
For HR professionals, the ruling lands on two pressure points. The first is documentation around retention decisions and disciplinary records. Plaintiffs have routinely used negligent retention claims to surface prior incidents, internal reviews, and HR files – material the court said would otherwise be inadmissible and unfairly prejudicial to both the employee and the employer. Iowa employers who stipulate to vicarious liability now have a much stronger basis to keep that material out of trial. The second is litigation strategy. Conceding vicarious liability early can collapse a case into a single, narrower theory and shut down the kind of expansive discovery that drives up cost and reputational risk.
The court also rejected the argument that recent Iowa legislation creating a preemption rule specifically for commercial motor vehicle cases meant lawmakers wanted the opposite result elsewhere. The opinion treated that statute as a targeted fix for a heavily regulated industry, not a broader signal about hospitals or other workplaces.
One open door remains. Several states applying the preemption rule recognize an exception where the plaintiff can show a viable punitive damages claim against the employer based on its own retention conduct. The Iowa Supreme Court did not decide whether to adopt that exception because the punitive claim here failed on the merits. Expert testimony that characterized the nurse's conduct as reckless and indefensible was, in the court's view, a conclusory opinion that lacked the factual analysis needed to show intentional rather than merely negligent conduct.
The court also reversed the lower court on bystander emotional distress damages for Rhonda, holding that her testimony did not show contemporaneous perception of the injury-producing event. She heard a noise and initially assumed the nurse had dropped the bed; her understanding of what had actually happened came later, from what others told her.
The case has been reversed and remanded. The Iowa Supreme Court's ruling on the legal questions is final.
