Superior Oil Company v. City Port Arthur

Appellant, Superior Oil Company, filed this suit against the City of Port Arthur, attacking the validity of an annexation ordinance and to enjoin the City from attempting to collect any ad valorem taxes from appellant on its property in question, and in the alternative seeking a declaration that the "discriminatory failure of Defendants to include Plaintiffs property in an industrial district is an unconstitutional denial of the equal protection of the laws" and that "Plaintiff is entitled to have its property taxed on the same basis as property included in industrial districts by the City...." The trial court granted the Citys motion for summary judgment, upholding the validity of the questioned annexation ordinance.
