In Exxon Corp. v. Perez, 842 S.W.2d 629, 630, 35 Tex. Sup. Ct. J. 1120 (Tex. 1992), the Court addressed the parameters of the borrowed-servant doctrine in the context of the borrowing entity's claim that it was entitled to rely on the exclusive remedy provision of the former workers' compensation act. Perez, an employee of Hancock, was injured on a jobsite and sued Exxon. Exxon contended that Perez was its borrowed servant, and that since it was a workers' compensation insurance subscriber, the exclusive remedy provision immunized it from common-law negligence claims. The Court held that there was a fact question about whether Perez was Exxon's borrowed servant and that the trial court therefore should have submitted an issue to the jury. The Court did not consider in any way whether Perez's employer, Hancock, would be precluded from relying on the exclusive remedy provision if Perez were found to be Exxon's borrowed servant.
