Which court in Texas has the highest appellate jurisdiction?

The Texas Supreme Court holds the highest appellate jurisdiction in the state of Texas. This court is the court of last resort for civil cases and has the authority to oversee and interpret the law, making final decisions on matters of law and legal interpretation. It reviews decisions made by the lower appellate courts, specifically the Texas Court of Appeals, ensuring that legal principles are applied consistently across the state. This court's rulings can set precedent, influencing future cases and guiding lower courts.

In contrast, the Texas Court of Appeals hears appeals from lower trial courts and makes determinations about the outcomes of those cases, but it does not have the ultimate authority that the Texas Supreme Court possesses. The Texas District Court handles trial-level cases and does not serve the same appellate function, while the Texas Municipal Court typically addresses violations of city ordinances and does not operate at an appellate level. Thus, the structure of Texas's judicial system places the Texas Supreme Court at the apex of appellate jurisdiction.
