Nustar Energy, L.P. v. Kelly Hancock, Comptroller of Public Accounts of the State of Texas; And Ken Paxton, Attorney General of the State of Texas
Headline: Appellate Court Reverses, Upholds Texas Franchise Tax on Interstate Pipeline Operator
Case Summary
This case involves Nustar Energy, L.P.'s challenge to a Texas state tax assessment. Nustar, an interstate pipeline operator, argued that the Comptroller of Public Accounts incorrectly calculated its state franchise tax by including income from its pipeline operations, which Nustar contended should be excluded under the Commerce Clause of the U.S. Constitution. Nustar operates pipelines that transport crude oil and refined products across state lines, and it argued that the income generated from these interstate activities should not be subject to Texas's franchise tax. The trial court sided with Nustar, granting summary judgment and ordering a refund of the taxes paid. The Comptroller appealed, arguing that Nustar's activities within Texas, such as maintaining pipelines, pumping stations, and employees, constituted sufficient nexus for taxation and that the tax was fairly apportioned. The appellate court reviewed the trial court's decision, focusing on whether the franchise tax, as applied to Nustar, violated the Commerce Clause. The court ultimately reversed the trial court's judgment, finding that the Texas franchise tax, as applied to Nustar, did not violate the Commerce Clause. The appellate court concluded that Nustar's in-state activities created a substantial nexus with Texas, the tax was fairly apportioned, did not discriminate against interstate commerce, and was fairly related to the services provided by the state. Therefore, the appellate court ruled in favor of the Comptroller, denying Nustar's claim for a tax refund.
