The Texas Court of Appeals has denied a petition for a writ of mandamus from MV Transportation, Inc. and Amber Morgan. This decision affects their upcoming trial scheduled for October 5, 2026. The court's ruling means that the trial will proceed as planned, which could have significant implications for the parties involved.
The case centers around a dispute involving Jessica Casillas, who is the real party in interest in this matter. The court's decision to deny the petition and the emergency motion for a stay means that the legal proceedings will continue without interruption. This ruling is important for both the relators and the plaintiff, as it sets the stage for the upcoming trial.
Background
MV Transportation, Inc. is a transportation company that provides services in various regions, and Amber Morgan is associated with the company. They filed the petition for writ of mandamus in response to a trial set to begin on October 5, 2026, in the 150th Judicial District Court of Bexar County, Texas. The case they are involved in is titled Jessica Casillas v. Amber Morgan, under Cause No. 2024-CI-10501.
The relators sought the writ of mandamus to challenge a decision made by the lower court, but specific details about the nature of the dispute were not provided in the court filing. The relators also filed an emergency motion for a temporary stay of the trial, which was denied as moot by the appellate court.
The Ruling
The Texas Court of Appeals, sitting in San Antonio, issued its ruling on October 2, 2026. The court, composed of Justices Irene Rios, H. Todd McCray, and Velia J. Meza, concluded that the relators were not entitled to the relief they sought. The court stated, "After considering relators’ petition, the real party’s response, and the mandamus record, we conclude relators are not entitled to the relief sought."
This ruling effectively means that the trial will proceed as scheduled, and the relators will not receive the temporary relief they requested. The court's decision reflects its determination that the lower court's proceedings should continue without interruption.
Impact
The denial of the mandamus petition has significant implications for MV Transportation and Amber Morgan. By allowing the trial to proceed, the court has reinforced the authority of the lower court to manage its own proceedings. This could influence how similar cases are handled in the future, as it emphasizes the importance of following through with scheduled trials unless there are compelling reasons to delay.
Additionally, this ruling may affect how parties approach seeking mandamus relief in Texas courts. It highlights the challenges that relators face when attempting to interrupt ongoing litigation. The outcome of the trial could also have financial and reputational consequences for MV Transportation and Amber Morgan, depending on the verdict.
What's Next
With the court denying the petition for writ of mandamus, the trial is set to proceed on October 5, 2026. There is no indication in the court filing that an appeal is planned at this stage. However, should the trial result in an unfavorable outcome for the relators, they may consider further legal options following the trial.
