The Texas Court of Appeals recently denied a petition filed by William Thompson, the elected District Attorney of Navarro County, seeking to reverse his disqualification from representing the State of Texas in a criminal case. This ruling affects Thompson's ability to prosecute a case against Edward R. Monk, who faces serious felony charges. The decision highlights the complexities surrounding the disqualification of prosecutors and the legal standards required to challenge such decisions.

Thompson's petition for a writ of mandamus was filed on June 25, 2026, under docket number 10-26-00220-CR. The court's ruling emphasizes the importance of proper legal procedures and documentation in cases involving disqualification. The outcome is significant not only for Thompson but also for the legal community in Navarro County, as it could set a precedent for future cases involving similar issues.

Background

William Thompson is the District Attorney for Navarro County, Texas. He became involved in a criminal case against Edward R. Monk, who was indicted by a grand jury for multiple felony offenses, including theft of over $300,000 from a non-profit corporation. Monk, who served as a priest at a local church, allegedly misappropriated funds intended for the church. The church initiated its own internal proceedings to determine Monk's fate, which included a “church trial.”

During the church trial, Thompson testified as a witness. He provided details about the investigative process that led to Monk's indictment and discussed the bank records he had subpoenaed. Following Thompson's testimony, Monk filed a motion to disqualify him from the case, claiming a conflict of interest. The presiding judge, James Lagomarsino, held a hearing on the motion and ultimately granted Monk's request for disqualification. This led Thompson to seek a writ of mandamus to compel the judge to reverse the disqualification order.

The Ruling

The Texas Court of Appeals denied Thompson's petition for a writ of mandamus. The court ruled that Thompson did not meet the necessary legal standards to overturn the disqualification. The court stated, “Because Relator failed to provide this Court with a record sufficient to establish his entitlement to relief, we deny his petition for writ of mandamus.” This ruling was delivered by Justice Steve Smith, with the opinion also reviewed by Chief Justice Johnson and Justice Harris.

The court explained that to qualify for a writ of mandamus, a petitioner must show that they have no adequate remedy at law and that they have a clear and indisputable right to the relief sought. The court acknowledged that all parties agreed Thompson had no adequate remedy at law since the State cannot appeal a disqualification order. However, the court found that Thompson did not demonstrate a clear right to relief, as he failed to provide sufficient documentation to support his claims.

Impact

This ruling has significant implications for Thompson and the prosecution of the case against Monk. By denying the writ of mandamus, the court effectively upholds the disqualification ruling, which means Thompson cannot represent the State in this high-profile case. This decision could impact how future disqualification motions are handled in Texas, particularly concerning the standards for proving actual prejudice in disqualification cases.

The ruling also underscores the importance of proper documentation and adherence to legal procedures in legal proceedings. The court emphasized that Thompson did not provide a certified or sworn copy of the necessary documents or a transcript of the disqualification hearing, which ultimately led to the denial of his petition. This case serves as a reminder for attorneys to ensure they follow procedural rules when seeking relief from the courts.

What's Next

Thompson may consider appealing this decision, but details about any potential appeal were not available in the court filing. As of now, there are no related cases pending that could influence this ruling. The outcome of this case will likely shape how similar cases are approached in the future, particularly regarding the disqualification of prosecutors in Texas.
