Different courthouse, different “Casteel” rule

In 2018, the Texas Supreme Court and the Fifth Circuit have taken different approaches to an important type of “Casteel” problem, in which a jury question has several legally viable theories, some of which are not supported with adequate evidence.

Federal. After a thorough (and infrequently-seen) summary of how federal law has developed on the “Casteel problem” of commingled liability theories, the Fifth Circuit concluded in Nester v. Textron, Inc., 888 F.3d 151 (5th Cir. 2018): “We will not reverse a verdict simply because the jury might have decided on a ground that was supported by insufficient evidence.” (applying, inter alia, Griffin v. United States, 502 U.S. 46 (1991)).

State. In Benge v. Williams, 548 S.W.3d 466 (Tex. 2018), a medical-malpractice case, the Texas Supreme Court observed: “The jury question in the present case, unlike the one in Casteel, did not include multiple theories, some valid and some invalid. It inquired about a single theory: negligence. But we have twice held that when the question allows a finding of liability based on evidence that cannot support recovery, the same presumption-of-harm rule must be applied.”
