This question has been addressed in 1 Texas court opinion:
COA04 — January 28, 2026
After Solaris Transportation filed a petition for a writ of mandamus to challenge an invasive trial court order authorizing discovery into its net worth, the opposing parties attempted to moot the proceeding by filing a unilateral stipulation withdrawing the contested requests. The Fourth Court of Appeals denied the motion to dismiss, reasoning that a unilateral stipulation lacks the "enforceable assurances" required to render a case moot because it remains subject to the trial court's discretion. The court held that unless the withdrawal is backed by a binding Rule 11 agreement or a court order vacating the discovery with prejudice, the threat of recurring invasive discovery remains, and the appellate court retains jurisdiction to hear the mandamus.
Litigation Takeaway
“A party cannot escape appellate review of an invasive discovery order through a "tactical withdrawal" unless they provide a binding, enforceable guarantee—such as a Rule 11 agreement or a court order with prejudice—that the discovery dispute will not recur.”
