Strict enforcement of amended Rule 702 eliminated hundreds of baby food injury claims — proving that tightened federal evidentiary standards are stopping speculative mass torts before trial.
BackgroundAmended Federal Rule of Evidence 702 mandates that plaintiffs prove by a preponderance of the evidence that expert methodology is reliably applied to facts. Lawsuits alleged that heavy metals in baby foods caused neurological developmental conditions like autism and ADHD.
- The presiding court excluded plaintiffs' general causation experts after finding their epidemiological methodology lacked reliable scientific grounding under federal evidentiary rules.
- The exclusion granted summary judgment for food manufacturers including Kraft Heinz and Gerber, wiping out nearly half the active federal docket in a single order.
- Mass tort litigators noted the decision underscores how amended Rule 702 is curbing speculative medical causation claims across consumer product injury proceedings.
