Union Carbide v. Sommerville

On February 17, 2026, WLF asked the Supreme Court to grant certiorari and reverse a Fourth Circuit decision that flouts Rule 702’s mandate for judges to ensure expert testimony’s factual reliability. WLF contends that the Fourth Circuit’s ruling revives a defunct pre-Daubert view of admissibility, eroding judicial gatekeeping and inviting unfair verdicts built on speculation. WLF’s brief shows that the decision below relies on a string of archaic precedents that are no longer good law.
