The Texas Court of Appeals has denied a petition for writ of mandamus filed by LyondellBasell Acetyls, LLC. This decision affects the company's ongoing legal battle in Harris County. The court's ruling means that LyondellBasell must continue to face the lower court's decisions regarding its previous motions.

The case, docketed as 01-26-00513-CV, stems from a dispute involving LyondellBasell and several other parties in a case known as Blanco, et al. v. Brock Services, LLC, et al. The court's ruling is significant as it denies LyondellBasell's attempts to overturn prior decisions made by a district court.

Background

LyondellBasell Acetyls, LLC is a chemical manufacturing company that produces acetyls and related products. The company filed a petition for writ of mandamus after the district court denied its motion for summary judgment on December 5, 2025. This ruling was a setback for LyondellBasell in its ongoing litigation.

The underlying case involves multiple parties, including Brock Services, LLC, and is currently pending in the 269th District Court of Harris County, Texas. The presiding judge in that case is Honorable Cory Don Sepolio. The dispute likely involves issues related to liability and damages, but specific details were not available in the court filing.

After the December ruling, LyondellBasell sought reconsideration of the court's decision, but that motion was also denied on May 1, 2026. This prompted the company to escalate the matter to the Texas Court of Appeals, seeking a writ of mandamus to compel the lower court to grant its motion for summary judgment.

The Ruling

The Texas Court of Appeals reviewed LyondellBasell's petition and ultimately denied it. The court stated, "We deny the petition and lift the stay imposed in our May 29, 2026 order." This ruling indicates that the appellate court found no merit in LyondellBasell's arguments for overturning the lower court's decisions.

The panel of justices who reviewed the case included Justices Rivas-Molloy, Johnson, and Dokupil. Their decision to deny the mandamus petition means that LyondellBasell must continue with the litigation as determined by the lower court.

Impact

This ruling has significant implications for LyondellBasell and the other parties involved in the underlying case. By denying the mandamus petition, the Texas Court of Appeals has reinforced the district court's authority and decisions. This may affect how LyondellBasell approaches its legal strategy moving forward.

Additionally, the court's decision could impact similar cases in Texas, as it underscores the challenges companies face when seeking to overturn lower court decisions through mandamus petitions. The ruling clarifies that appellate courts will closely scrutinize such requests and may deny them if they do not find sufficient grounds.

What's Next

Details regarding the next steps for LyondellBasell were not available in the court filing. However, the company may still pursue its case in the lower court, as the appellate court's ruling does not preclude further legal action. There may also be related cases pending, but specific information was not provided.
