Opinion issued August 26, 2025

In The

Court of Appeals

For The

First District of Texas

Janssen, and Alline Henderson (collectively, “the patients”) sued OakBend Medical Center and its subsidiary OakBend Medical Group after their personal identifying information and personal health information (“personal information”) were potentially stolen in a cyberattack. The two OakBend entities filed pleas to the jurisdiction, arguing that the claims asserted against them did not fall within a waiver of governmental immunity. The trial court granted the pleas to the jurisdiction and dismissed all claims with prejudice.

On appeal, the patients contend that (1) OakBend Medical Group is a private nonprofit corporation and is not entitled to governmental immunity; (2) the tort claims fall within the “condition or use of tangible personal property” waiver of immunity found in the Texas Tort Claims Act; and (3) governmental immunity does not protect the OakBend entities from the claim for unjust enrichment.

We affirm as to the parent and reverse and remand as to the subsidiary.

Background

In September 2022, cyber criminals launched a ransomware attack against the computer network and servers of OakBend Medical Center, a hospital authority that provides medical services to patients primarily in Fort Bend County. Although OakBend quickly learned of the attack and was able to take some measures to protect its system, the criminals accessed personal information relating to current and former patients and employees. This personal information may have included names,

mailing addresses, email addresses, phone numbers, Social Security numbers, dates of birth, and medical information. OakBend reported the attack to law enforcement authorities. OakBend also mailed letters to all potentially affected patients and employees, notifying them of the data breach and providing free credit monitoring for eighteen months.

Kimberly Somer, a former patient of OakBend, sued both OakBend Medical Center and OakBend Medical Group on her own behalf and on behalf of all others similarly situated. Somer’s petition referred to OakBend Medical Center and OakBend Medical Group collectively as “OakBend.” She did not differentiate between the two OakBend entities when describing the acts and omissions that allegedly caused her injuries.

Somer asserted a claim for negligence, alleging that OakBend knew of an increasing risk of cyberattacks on healthcare providers but failed to exercise reasonable care to safeguard and protect her personal information. As a result of OakBend’s negligence, Somer suffered harm including a substantially increased risk of identity theft. She also asserted a claim for negligence per se, alleging that OakBend’s conduct violated duties established by the Federal Trade Commission Act and HIPAA, a claim for breach of fiduciary duty, and a claim for breach of an

implied contract.1 Finally, she raised a claim for unjust enrichment, alleging that by paying OakBend for medical services, she also paid for “reasonable data privacy and security practices and procedures,” but OakBend failed to implement proper data security procedures and therefore it should not retain the monetary benefit it received from Somer and other class members. Somer’s lawsuit was assigned to the 434th District Court of Fort Bend County.

Somer was not the only former patient potentially affected by the data breach to file suit. Alline Henderson, Cody Janssen, and Janssen’s minor daughter were all former patients of OakBend, and Janssen was also a former employee. They filed a class action lawsuit solely against OakBend Medical Center and asserted nearly identical claims to Somer: negligence, negligence per se, breach of fiduciary duty, breach of an implied contract, and unjust enrichment.2 Janssen and Henderson’s lawsuit was assigned to the 240th District Court of Fort Bend County.

1 In later filings, Somer agreed to non-suit her implied contract claim. That claim is therefore no longer at issue in this appeal.

2 Like Somer, Janssen and Henderson later agreed to non-suit their claim for breach of an implied contract, and this claim is not at issue in this appeal. They also asserted a claim for intrusion upon seclusion/invasion of privacy, but they later requested that the trial court dismiss this claim without prejudice to refiling. The trial court did so. This claim is therefore also not at issue in this appeal.

OakBend Medical Center filed a plea to the jurisdiction in Somer’s suit, arguing that its governmental immunity barred Somer’s claims against it.3 OakBend Medical Center argued that as a hospital authority created by the City of Richmond, it was a political subdivision of the state and had governmental immunity from suit. See TEX. HEALTH & SAFETY CODE § 262.003(a) (allowing governing body of municipality to adopt ordinance creating hospital authority). It further argued that no waiver of governmental immunity applied to Somer’s claims. It acknowledged that the Texas Tort Claims Act contains limited waivers of governmental immunity, including a waiver for personal injury or death “caused by a condition or use of tangible personal or real property,” but it contended that this waiver did not apply because personal information—the alleged theft of which formed the crux of all Somer’s claims—was not tangible personal property. It also argued that no waiver of immunity applied to Somer’s unjust enrichment claim, which sought monetary

3 In addition to its arguments relating to immunity from suit, OakBend Medical Center—as well as OakBend Medical Group in its plea to the jurisdiction—also challenged Somer’s standing to bring suit. OakBend Medical Center’s plea to the jurisdiction filed in Janssen and Henderson’s suit also challenged standing. When the trial court granted the OakBend entities’ pleas to the jurisdiction, it struck through the portion of the proposed orders relating to standing. Additionally, in separate filings from the pleas to the jurisdiction, the OakBend entities moved to dismiss both suits under Rule of Civil Procedure 91a, arguing that the patients’

claims had no basis in law. See TEX. R. CIV. P. 91a.1. The trial court ruled only on the pleas to the jurisdiction, not on the Rule 91a motions to dismiss. On appeal, the OakBend entities do not argue that these actions by the trial court were erroneous.

damages. OakBend Medical Center filed a substantively identical plea to the jurisdiction in Janssen and Henderson’s suit.

OakBend Medical Group filed a separate plea to the jurisdiction. It also argued that governmental immunity barred Somer’s suit, but it relied on a slightly different source for its immunity: although it was not a political subdivision of the state, it was controlled and funded by OakBend Medical Center. As supporting evidence, OakBend Medical Group attached the declaration of Joseph Freudenberger, the CEO of OakBend Medical Center and the president of OakBend Medical Group, who discussed the ownership and funding of OakBend Medical Group:

OakBend Medical Group is a Texas nonprofit corporation certified by the Texas Medical Board. The sole member of OakBend Medical Group is OakBend Medical Center. As the member, OakBend Medical Center has the power to appoint and remove the Board and management. Additionally, other powers reserved to the member include: approval of all budgets, mergers, acquisitions and sale of real assets; creation of partnerships or joint ventures and dissolution or liquidation, among other powers. OakBend Medical Center provides funding for the operations of OakBend Medical Group.

OakBend Medical Group argued that due to the relationship between the entities, it shared OakBend Medical Center’s immunity from suit, which was not waived for any of Somer’s claims.
