Kerr-McGee Corporation v. Jimmy Helton

Summary

The Texas Supreme Court reversed the Court of Appeals judgment, holding that the expert testimony of Michael Riley on damages was unreliable and therefore constituted no evidence, so the trial court's damages award was unsupported. The Court also held that Kerr‑McGee's motion to strike Riley's testimony after cross‑examination was timely and preserved error for appeal. Justice Hecht, joined by Justice Wainwright, filed a concurring opinion emphasizing the analytical gap in Riley's testimony.
