Iowa's Supreme Court tossed a $2.84 million workplace death verdict, reinforcing that workers' comp immunity requires actual knowledge of hazards.
The February 6 decision makes clear that knowing a workplace is generally dangerous isn't enough. Courts require proof that supervisors had actual knowledge of the specific hazard that caused the injury. For workers' compensation insurers and claims professionals, the ruling offers important guidance on defending against gross negligence exceptions to workers' comp exclusivity.
Michael Griffith had been working as a stockpiler at Wendling Quarries in Garrison, Iowa, for just over a week when he died on January 8, 2020. His job involved climbing onto a catwalk surrounding a lime surge hopper, a large bin that collects processed limestone, and using a long pole to scrape accumulated lime dust from the sides.
The catwalk had a railing with a gate designed to be secured by metal pins. But when Griffith fell through the gate into the hopper and was buried in lime, investigators discovered the pins were missing. Instead, someone had secured the gate with a piece of wire.
Griffith's widow and father sued three of his co-workers under Iowa's narrow exception to workers' compensation immunity, which allows lawsuits against co-employees for gross negligence. The case went to trial against two defendants: Travis Galloway, Griffith's supervisor, and John Kulper, the company's safety and environmental director.
At the eight-day trial in April 2023, jurors heard that Galloway had inspected the hopper on the morning of the accident, but only briefly, from his truck, using his headlights. He never climbed up to check the gate or pins. Kulper wasn't at the quarry that day and wasn't responsible for day-to-day operations. The jury awarded the family roughly $2.8 million.
But the defendants argued the family failed to meet Iowa's strict test for co-employee gross negligence, which requires proving three elements: knowledge of the danger, knowledge that injury was probable rather than merely possible, and a conscious failure to avoid the danger.
The Iowa Supreme Court, in a unanimous opinion by Justice Waterman, zeroed in on a critical distinction. Under Iowa law, it's not enough to show that supervisors should have known about a hazard. Plaintiffs must prove they actually knew.
The court pointed to its 1992 decision in Walker v. Mlakar, which rejected the idea that constructive knowledge satisfies the legal standard. As the court explained, you can't consciously fail to avoid a danger you don't actually know exists.
In this case, both Galloway and Kulper testified they didn't know the pins were missing or that the gate was improperly secured. No one contradicted that testimony. Galloway acknowledged that he would have stopped anyone from climbing the hopper if he'd known about the missing pins. But his failure to conduct a thorough inspection didn't change the outcome.
The court found that while Galloway's cursory inspection might constitute ordinary negligence, it didn't meet the higher threshold for gross negligence. Kulper's liability was even more tenuous since he wasn't present at the site.
The family's lawyers argued that the supervisor's inadequate inspection should be enough, pointing to evidence that a proper inspection would have revealed the problem. But the Supreme Court disagreed, noting that imputing knowledge based on what an inspection would have shown conflicts with the actual knowledge requirement.
The court reviewed several prior cases that illustrated the demanding standard. In Taylor v. Peck, a plant manager wasn't liable even though he walked past a worker the morning of her accident, unaware that a safety feature on her machine had been disabled. The court distinguished cases where gross negligence claims succeeded, like Alden v. Genie Industries, where a supervisor admitted in his deposition that operating a manlift without stabilizing outriggers was unsafe and there was evidence he ordered workers to proceed anyway.
Those cases involved direct, specific knowledge of the hazard. Here, the court found, supervisors knew the hopper was generally dangerous but had no actual knowledge of the missing pins.
The Iowa Court of Appeals had affirmed the jury verdict, concluding that circumstances including an unsecured gate, missing pins, and a cursory pre-dawn inspection made the injury probable. But the Supreme Court found the appeals court had impermissibly relied on constructive knowledge, essentially basing liability on what Galloway should have discovered.
For workers' compensation insurers and claims adjusters, the decision reinforces several key points in defending against gross negligence claims. General awareness of workplace hazards isn't sufficient. Neither is evidence that proper procedures would have discovered the problem. The plaintiff must produce evidence that the defendant had specific, actual knowledge of the particular hazard that caused the injury.
The ruling vacated the Court of Appeals decision, reversed the district court judgment, and sent the case back with instructions to dismiss the lawsuit.
