Williams v. Sig Sauer, Inc.

On February 27, 2026, WLF urged the Fourth Circuit to affirm a district court’s exclusion of a plaintiff’s expert testimony in a product liability case, which resulted in summary judgment for the defendant. WLF’s amicus brief contends that the district court correctly applied amended Rule 702 by barring unqualified and unreliable opinions that threatened to mislead the jury and circumvent judicial gatekeeping.
