2026 Tex. Bus. 56 Summary Judgment August 10, 2026

Claim Preclusion Bars Refiled Knowing-Participation Claim Against Prior Party, But Not Against Non-Party Employee

In CAM Industrial Solutions v. Brown & Root Industrial Services, the Business Court granted summary judgment on claim-preclusion grounds to a defendant sued in both a prior district court action and the current Business Court case, but denied summary judgment to a former employee who was a non-party witness in the first action and was not shown to be in privity with any party. The decision addresses whether a plaintiff can evade preclusion by filing a second suit one day before entry of judgment in the first.
