The Texas Supreme Court has revived a lawsuit by Willacy County property owners challenging a decades-old property tax that was originally approved by voters in 1974 to serve individuals with disabilities, but has instead financed a regional magnet school system for more than 40 years.
The May 8 ruling in Busse v. South Texas Independent School District allows the taxpayers’ challenge to proceed, while scaling back a legal doctrine that local governments have long used to block challenges to entrenched public levies.
South Texas ISD (STISD) originated in 1963 as the Rio Grande Rehabilitation District for Handicapped Persons. Willacy County voters approved a tax of up to 5 cents per $100 of assessed value in 1974 exclusively to fund those specialized disability services.
However, following federal mandates requiring all public schools to educate students with disabilities, the Texas Legislature in 1983 allowed rehabilitation districts to pivot toward providing general vocational training. The district subsequently rebranded as South Texas ISD and grew into what it describes as the state’s only all-magnet school district, spanning three counties and more than 3,600 square miles.
A group of local taxpayers and the neighboring Lyford Consolidated Independent School District filed suit in 2023, arguing that students with disabilities now represent a negligible share of STISD’s total enrollment and that voters never authorized a general school-district tax.
The plaintiffs invoked the Texas Constitution’s “contract with the voters” protections, which require explicit voter approval for the specific intent of a school district levy. While a trial court allowed the case to move forward, the 13th Court of Appeals initially dismissed it, ruling that residents had “effectively ratified” the tax by paying it for 40 years and that disrupting the funding would harm government operations.
Writing for the Supreme Court, Justice Rebeca Huddle rejected the appellate court’s logic regarding standing. Huddle determined that the taxpayers’ alleged “pocketbook injury” is concrete, traceable, and fixable by a court. “Whether substantial disruption would result from a court’s judgment is not a proper standing inquiry,” Huddle said.
The legal challenge spotlights a vast financial disparity between the regional magnet network and its traditional neighbors. According to South Texas ISD’s 2022 Annual Financial Report, the district held more than $40 million in unassigned reserves, compared to roughly $6 million maintained by Lyford CISD.
STISD also remains exempt from the state’s “recapture” system, which redistributes property wealth among Texas public schools. Commenting on the structural dispute, municipal attorney Art Martinez de Vara argued that the core of the challenge hinges on fundamental baseline accountability, stating that the central legal issue is not the collection of the tax itself, but rather its expenditure on uses not originally authorized by voters.
The dispute underscores a long-standing tension regarding “taxpayer standing” in Texas, which state courts have historically kept narrow to prevent continuous legal challenges to routine public expenditures.
Previous legislative attempts to resolve the funding structure have stalled; State Representative Sergio Muñoz Jr. (D-Mission) filed two bills in 2023 to phase out the tax or let local voters abolish it, but both measures died in committee.
The case now returns to the 13th Court of Appeals to evaluate STISD’s remaining statutory defenses, including governmental immunity, before the case can return to a trial court for a final determination on whether the tax itself violates the Texas Constitution.
