Tex. Local Government Code § 143.1214

(a) The human resources director for the department promptly shall order that the records of a disciplinary action that was taken against a fire fighter or police officer be expunged from each file maintained on the fire fighter or police officer by the department if the disciplinary action was entirely overturned on appeal by the commission, an independent third-party hearing examiner, or a court of competent jurisdiction. Documents that must be expunged under this subsection include all documents that indicate disciplinary action was recommended or taken against the fire fighter or police officer, such as the recommendations of a disciplinary committee or a letter of suspension. This subsection does not apply if the fire fighter or police officer is charged with using excessive force that results in a death or injury and the charge is being investigated by a law enforcement or criminal justice agency other than the department. This subsection does not require that records of an internal affairs division or other similar internal investigative division be expunged.

(b) The department shall maintain an investigatory file that relates to a disciplinary action against a fire fighter or police officer that was overturned on appeal, or any document in the possession of the department that relates to a charge of misconduct against a fire fighter or police officer, regardless of whether the charge is sustained, only in a file created by the department for the department's use. The department may only release information in those investigatory files or documents relating to a charge of misconduct:

(1) to another law enforcement agency or fire department;

(2) to the office of a district or United States attorney; or

(3) in accordance with Subsection (c).

(c) The department head or the department head's designee may forward a document that relates to disciplinary action against a fire fighter or police officer to the director or the director's designee for inclusion in the fire fighter's or police officer's personnel file maintained under Sections 143.089(a)-(f) only if:

(1) disciplinary action was actually taken against the fire fighter or police officer;

(2) the document shows the disciplinary action taken; and

(3) the document includes at least a brief summary of the facts on which the disciplinary action was based.

(d) The legal division of the municipality, or its designee, shall provide legal representation in any action related to the release of a file or part of a file.

(e) The requirements of this section are in addition to the requirements of Section 143.089. This section does not prevent a fire fighter or police officer from obtaining access to any personnel file maintained by the director or the department, other than a file maintained by an internal affairs division or other similar internal investigative division, on the fire fighter or police officer under Section 143.089.
