Background

Westlake Chemical Corporation and Westlake US 2 LLC sought mandamus relief in an underlying Harris County lawsuit brought by Matthew McPherson. The case was pending before Judge Michael Gomez in the 129th District Court.

The relators asked the First Court of Appeals to direct the trial court to grant their motion for summary judgment. The memorandum opinion does not describe the claims, the grounds asserted for summary judgment, or the trial court’s reasoning.

The Court’s Holding

The court denied the petition for a writ of mandamus under Texas Rule of Appellate Procedure 52.8(a). It therefore declined to order the trial court to grant summary judgment.

The per curiam opinion provided no substantive analysis of the summary-judgment issues or the requirements for mandamus relief. It also dismissed all pending motions as moot.

Key Takeaways

  • The First Court of Appeals denied Westlake’s request for mandamus relief.
  • The court did not direct the trial court to grant the relators’ summary-judgment motion.
  • The brief per curiam opinion did not address the merits of the underlying claims or explain the basis for denying relief.

Why It Matters

The decision leaves the underlying Harris County litigation in the trial court without the extraordinary appellate intervention Westlake requested. Because the opinion contains no substantive reasoning, it establishes little guidance beyond the disposition of this particular mandamus petition.
