ANR Pipeline Co., et al. v. Louisiana Tax Comm'n, et al., No. 11-30101 (5th Cir. 2011)
Annotate this CaseAppellants, owners of interstate natural gas pipelines subject to a 25% ad valorem tax under Louisiana Constitution article 7, section 18, brought and won a state court suit alleging certain intrastate pipelines were unconstitutionally given more favorable tax treatment by being taxed only 15% from 1994-2003. At issue was whether the state court's revaluation process violated the Due Process, Equal Protection, and Commerce Clauses, via 42 U.S.C. 1983, where that court ordered appellants' tax liability to be recalculated under the same fair-market-value determination process to which the intrastate pipelines were subjected. The court held that the district court properly dismissed appellants' suit because their federal claims were barred by the Tax Injunction Act, 28 U.S.C. 1341, which deprived the federal courts of jurisdiction over suits that sought to interfere with the administration of state tax systems so long as the state provided an adequate procedural vehicle for raising the claims and where appellants have raised their claims in state court and the Louisiana courts did not cease to provide a plain, speedy, or efficient remedy for appellants' injuries. Accordingly, the district court properly granted defendants' motion to dismiss.
