Background
LyondellBasell Acetyls, LLC sought mandamus relief in an underlying lawsuit pending before Judge Cory Don Sepolio in the 269th District Court of Harris County, Texas. The underlying case is Blanco, et al. v. Brock Services, LLC, et al., cause number 2024-56940.
LyondellBasell challenged the district court’s December 5, 2025 order denying its motion for summary judgment and its May 1, 2026 order denying reconsideration of that ruling. The court of appeals had imposed a stay on May 29, 2026, while the mandamus proceeding was pending.
The Court’s Holding
The Texas First Court of Appeals denied LyondellBasell’s petition for a writ of mandamus. The memorandum opinion did not provide substantive reasoning or address the merits of the summary-judgment arguments.
The court also lifted the stay imposed by its May 29, 2026 order and dismissed all pending motions as moot.
Key Takeaways
- The court denied mandamus relief from the orders denying summary judgment and reconsideration.
- The brief per curiam opinion did not explain the basis for denying the petition.
- The appellate stay was lifted, and all pending motions were dismissed as moot.
Why It Matters
The ruling leaves the district court’s challenged orders undisturbed and permits the underlying Harris County litigation to proceed without the appellate stay. Because the court supplied no substantive analysis, the opinion offers no broader guidance on summary-judgment standards or the availability of mandamus relief.
