The Texas Court of Appeals has denied a petition for writ of mandamus from Westlake Chemical Corporation and Westlake US 2 LLC. This decision affects the company's ongoing legal battle in Harris County, Texas, and could have significant implications for the case at hand.
The court's ruling came on July 28, 2026, in response to Westlake's request to compel a lower court to grant its motion for summary judgment in a related lawsuit. This ruling is important as it highlights the challenges companies face when seeking legal remedies in complex litigation.
Background
Westlake Chemical Corporation and its subsidiary, Westlake US 2 LLC, are involved in a legal dispute with Matthew McPherson. The underlying case, titled Matthew McPherson v. Westlake Chemical Corporation, Westlake Chemical Energy LLC, and Westlake Chemical OpCo LP, is pending in the 129th District Court of Harris County, Texas. The case number is 2022-55725, and Judge Michael Gomez is presiding over the matter.
The dispute centers around issues that have not been detailed in the court filing. However, Westlake's petition for a writ of mandamus indicates that they are seeking to resolve a significant legal question that could affect the outcome of the case. Mandamus is a legal remedy that allows a higher court to direct a lower court to take a specific action, in this case, to grant summary judgment.
Westlake Chemical Corporation is a major player in the chemical industry, known for producing a variety of chemical products. The company’s legal challenges could impact its business operations and reputation, making the outcome of this case particularly important to stakeholders.
The Ruling
The Texas Court of Appeals, which consists of Chief Justice Adams and Justices Rivas-Molloy and Guiney, ruled against Westlake Chemical's petition. The court stated, "We deny mandamus relief." This means that the court will not compel the lower court to grant Westlake's summary judgment motion.
The court also indicated that any pending motions related to this case are considered moot, meaning they are no longer relevant or necessary to address. This ruling effectively leaves Westlake without the immediate relief it sought from the appellate court.
Impact
The denial of Westlake's mandamus petition could have significant implications for the ongoing litigation in Harris County. By not granting the writ, the court has upheld the lower court's decision to not grant summary judgment at this time. This means that the case will continue to proceed through the judicial process, and Westlake will need to prepare for further legal challenges.
This ruling may also set a precedent for how similar cases are handled in the future. Companies seeking mandamus relief in Texas may find it more challenging to obtain favorable rulings, particularly if the courts are hesitant to intervene in lower court proceedings. The decision could influence how businesses approach litigation strategies, particularly in complex cases involving multiple parties.
What's Next
Westlake Chemical Corporation and Westlake US 2 LLC may still have options for appealing this decision, although the specifics were not detailed in the court filing. The ongoing case against Matthew McPherson will continue, and it remains to be seen how the parties will respond to this ruling in their future legal strategies.
