1 1. My name is Thanh D. Nguyen. I represent Relators in this Petition for

a Writ of Mandamus. I am a member in good standing of the State Bar of Texas. I

provide this Declaration in support of Relators’ Second Emergency Motion to Stay.

I have personal knowledge of the facts stated herein, and I could and would testify

thereto if called as a witness in this matter.

2. On March 26, 2025, the 493rd District Court held a hearing on two

motions: the State of Texas’s Motion to Seal Court Records and Nonparty Children’s

Health System of Texas’s (“Children’s”) Unopposed Motion to Seal Court Records.

The hearing was noticed for 8:30 a.m. The motions were not opposed by any party

or nonparty.

3. Regrettably, I arrived at the hearing about ten minutes late.

4. When I walked into the courtroom, the hearing had already begun, and

I sat in the gallery. The court’s bailiff approached me, and I let him know that I was

there to observe the hearings. I also conveyed that I was an attorney for the Relators,

but I did not anticipate having a speaking role.

5. I decided not to stand up, interrupt the proceedings, and ask that my

appearance be noted on the record.

2 6. I abstained from doing so because only two unopposed, uncontroversial

motions were set to be heard, my clients did not oppose the motion, and the

proceedings were unfolding smoothly.

7. Attached to Relators’ Second Emergency Motion to Stay as Exhibit A

is a true and correct copy of the Intervenor Texas Attorney General’s Verified

Motion to Show Authority in Cause No. 493-08026-2024.

8. Attached to Relators’ Second Emergency Motion to Stay as Exhibit B

is a true and correct copy of the transcript of the hearing held on March 26, 2025 in

the 493rd District Court.

9. Attached to Relators’ Second Emergency Motion to Stay as Exhibit C

is a true and correct copy of an email chain between counsel for the parties and

Relators in Cause Nos. 493-07676-2024, 493-08026-2024 concerning UTSW’s

production requirements.

10. Attached to Relators’ Second Emergency Motion to Stay as Exhibit D

is a true and correct copy of an email chain between counsel for the parties and

Relators in Cause Nos. 493-07676-2024, 493-08026-2024 and Ms. Amy Patterson,

Court Coordinator for the 493rd District Court.

11. Attached to Relators’ Second Emergency Motion to Stay as Exhibit E

is a true and correct copy of an email chain between counsel for the parties and

Relators in Cause Nos. 493-07676-2024, 493-08026-2024 concerning the

3 production of documents by UTSW. Pursuant to Tex. R. App. P. 9.9, I have redacted

a URL that connects a user to the Box website that stored patient records.

I declare under penalty of perjury that the foregoing is true and correct.

Executed in Dallas County, State of Texas, on the 2nd day of April, 2025.

THE STATE OF TEXAS, § IN THE DISTRICT COURT OF Plaintiff, § § § v. § COLLIN COUNTY, TEXAS § § M. BRETT COOPER, M.D., § Defendant. § 493rd JUDICIAL DISTRICT

INTERVENOR TEXAS ATTORNEY GENERAL’S VERIFIED MOTION TO SHOW AUTHORITY

Pursuant to Texas Rule of Civil Procedure 12, Ken Paxton, in his official capacity as the

Attorney General of Texas, files this Motion to Show Authority and challenges the authority of

retained counsel to appear on behalf of non-party University of Texas Southwestern Medical

Center (“UT Southwestern”) in this matter.

Texas Rule of Civil Procedure 12 authorizes any party to challenge an attorney’s authority

to represent a party in a lawsuit. 1 The burden of proof is on the challenged attorney to demonstrate

such authority. Tex. R. Civ. P. 12.

“Except as authorized by other law, a contract for legal services between an attorney, other

than a full-time employee of the agency, and a state agency in the executive department, other than

an agency established by the Texas Constitution, must be approved by the attorney general to be

valid.” Tex. Gov’t Code § 402.0212(a). The Texas Legislature reinforces this requirement in the

General Appropriations Act passed in each legislative session: “[a] state governmental entity may

not initiate the process of selecting outside legal counsel prior to receiving the approval of the

1 Here, UT Southwestern has indicated its intent to participate in this litigation as the subject of a subpoena, which may include appearing before this Court. See Tex. R. Civ. P. 176.6(d), (e).

Intervenor’s Motion to Show Authority Page 1 Attorney General to retain outside legal counsel.” General Appropriations Act (“GAA”), 88th

Leg., R.S., H.B. 1, ch. 1170, 2023 Tex. Gen. Laws (art. XI, § 16.01(a)(5)). For purposes of this

section, “state governmental entity” means a board, commission, department, office, or other

agency in the executive branch of state government created under the constitution or a statute,

including an institution of higher education. Id. at § 16.01(k) (emphasis added).

UT Southwestern is part of the University of Texas (“UT”) System. 2 UT System does

not dispute that Intervenor must grant permission to retain outside counsel: “By law, the Texas

Attorney General’s Office must approve all state agency contracts for outside legal services.

Within the UT System, every contract is approved by the Vice Chancellor and General Counsel.

For this reason, the Office of General Counsel coordinates all requests to the Texas Attorney

General for permission to retain counsel.” 3

Following the law and UT System policy, on or about January 21, 2025, UT Southwestern,

through UT System, requested permission from Intervenor to retain outside counsel to represent

it in responding to discovery in this lawsuit. See Exhibit A at pp. 1–2. That request was denied on

or about February 20, 2025. See id. at pp. 3–4.

Despite not receiving the permission required to retain outside counsel, it appears UT

Southwestern, in violation of state law, retained David Walsh of Kershaw Anderson King, PLLC

to represent it in this matter. Specifically, on or about March 3, 2025, Mr. Walsh represented to
