Third Circuit: Correlation Insufficient for Causation in Pharma TPP Class Actions

In-house counsel for pharmaceutical manufacturers and third-party payors must account for this binding precedent, as it blocks plaintiff efforts to certify TPP class actions using only temporal links between drug use and alleged harms.

The U.S. Court of Appeals for the Third Circuit ruled that temporal correlation between a pharmaceutical product and alleged patient harm does not meet the causation requirement for product liability claims, including third-party payor (TPP) class actions. The decision reaffirms that causation is a mandatory element of all product liability suits, and plaintiffs cannot rely on timing alone to prove a drug caused alleged injuries when seeking class certification. In-house counsel handling pharmaceutical product liability or TPP class action defense should cite this binding Third Circuit precedent to oppose class certification motions that rely solely on temporal correlation to establish causation.
