Proven verdicts and settlements

$6 millionVerdict

A Tarrant County jury found Walmart 80 percent at fault, including gross negligence, after a Walmart employee backed a customer's vehicle into Carl Chojnicki at a Walmart Auto Care Center in North Richland Hills, Texas, breaking his femur. On April 25, 2024, the jury awarded him $6 million: $1.482 million in compensatory damages and $4.518 million in exemplary damages. Walmart appealed, and while the appeal was pending the parties settled; the Fort Worth Court of Appeals set aside the trial court's judgment by agreement in October 2024, so no public dollar figure from the case legally stands today.
