In this case we must decide whether taxpayers who were sued for nonpayment of property taxes lost their entitlement to contest liability based on non-ownership when the taxing authorities non-suited after the taxpayers paid the disputed taxes under protest. We hold that they did not. Accordingly, the court of appeals erred in reversing the trial court’s denial of the taxing authorities’ plea to the jurisdiction. We reverse the court of appeals’ judgment and remand to the trial court.
The Harris County Appraisal District’s appraisal roll listed the petitioners, Ned B. Morris III, Daniel W. Shipper, Patrick A. Shipper, Anita Gibson, Mary Ann Moseley, Deborah L. Moore, Linda Shipper Bender, Caroline D. Armstrong, Pamela K. Moore, Joyce Salter, and James R. Hunt (collectively, “Taxpayers”) as the owners of 10.34 acres of land in Harris County, of which the Taxpayers actually owned 9.38 acres. They never administratively challenged the inclusion of the 0.96 acres they did not own. In 2004, the Houston Independent School District, Harris County, City of Houston, Harris County Education Department, Port of Houston Authority of Harris County, Harris County Flood Control District, Harris County Hospital District, and the Houston Community College System*fn1 sued the Taxpayers for twenty years of unpaid taxes on the 10.34 acres. The taxing authorities placed a lien on the properties to secure payment. As the Taxpayers only owned 9.38 of the 10.34 acres, they asserted their lack of ownership as an affirmative defense under section 42.09(b)(1) of the Tax Code. While the suit was pending, the Taxpayers, under protest, paid the taxes on the entire 10.34 acres because the taxing entities would not accept payment on only the 9.38 acres. The Taxpayers did so in order to stop further penalties and interest from accruing, to avoid foreclosure on the 9.38 acres they did own, and to avoid breaching a contract to sell the 9.38 acres. They then filed a counterclaim for a refund of the taxes, penalties, and interest they had paid on the 0.96 acres they did not own, totaling $180,000. Once the taxing entities received the payment, they non-suited their claims and the district court realigned the parties, designating the Taxpayers as plaintiffs.
