Unreported / Non-Citable
Background
William Thompson, the elected District Attorney of Navarro County, sought a writ of mandamus to compel trial court Judge James Lagomarsino to withdraw an order disqualifying him from prosecuting The State of Texas v. Edward R. Monk, a case involving theft allegations against a priest accused of misappropriating church funds exceeding $300,000.
Thompson had testified at a church disciplinary proceeding, having been sworn as a witness, where he described the investigative process underlying the criminal charges and detailed his review of bank records showing the alleged movement of church funds. After Monk filed a motion to disqualify the District Attorney, Judge Lagomarsino held a hearing and granted the disqualification motion. Thompson then petitioned for mandamus relief.
The Court’s Holding
The Tenth Court of Appeals denied Thompson’s petition, but on procedural rather than substantive grounds. The court acknowledged that trial courts have limited authority to disqualify prosecutors and may do so only within statutory parameters or when a conflict rises to the level of a due process violation requiring “actual prejudice.” Monk’s disqualification motion implicated Texas Disciplinary Rule of Professional Conduct 3.08, which prohibits a lawyer from acting as an advocate when they are a “witness necessary to establish an essential fact.”
However, the court found that Thompson failed to provide a sufficient record to support his mandamus claim. He submitted only an uncertified, unsworn letter ruling that expressly stated it should not be considered an order; he did not provide a transcript of the disqualification hearing; and he failed to submit the evidence the judge had considered in making his decision. Because the appellate record was incomplete, the court could not determine that Thompson had a “clear and indisputable right” to relief, the second prong required for mandamus relief.
Key Takeaways
- Mandamus petitioners bear the burden of providing a complete, properly authenticated record including all material documents, hearing transcripts, and evidence considered by the trial court.
- A prosecutor may be disqualified for a due process violation only when a defendant demonstrates “actual prejudice,” not merely the possibility of prejudice.
- Rule 3.08 of the Texas Disciplinary Rules prevents lawyers from serving as advocates when they are necessary witnesses to essential facts, creating potential conflicts in prosecutor roles.
- Procedural deficiencies in the appellate record may result in denial of mandamus relief even if the underlying merits might support the petitioner’s position.
Why It Matters
This decision reinforces that prosecutors seeking mandamus review of disqualification orders must comply strictly with appellate rules governing record submission. Thompson’s loss turned on his failure to present a complete record rather than on resolution of the substantive conflict-of-interest question, leaving unresolved whether his testimony at the church trial created a disqualifying conflict under Rule 3.08 or a due process violation.
The opinion establishes important boundaries for prosecutor disqualification in Texas: trial judges have limited discretion outside statutory grounds, and conflicts must rise to the level of actual constitutional prejudice. For prosecutors and defense counsel, the decision underscores the procedural rigor required in appellate mandamus practice and the care needed when prosecutors become witnesses in cases they prosecute.
