Supreme Court of Missouri / Feb 24, 2026
Christopher Hanshaw, Appellant, vs. Crown Equipment Corp., et al., Respondents.
Citation: Rule 702
The court affirmed the circuit court's decision to exclude Hanshaw's expert witness testimony and grant summary judgment to Crown Equipment in a product liability case involving an allegedly defectively designed forklift. The expert's opinions were properly excluded because they were not supported by reliable methodology, as the expert performed no tests and failed to demonstrate how cited research and data supported his conclusions.
