CORY L. CARLYLE, JUSTICE

On Appeal from the County Court at Law No. 3 Dallas County, Texas Trial Court Cause No. CC-20-05637-C

Before Justices Reichek, Carlyle, and Miskel

MEMORANDUM OPINION

CORY L. CARLYLE, JUSTICE

Charlotte Carroll sued CC Maple, LLC alleging breach of a contract related to COVID-19. CC Maple filed a no-evidence motion for summary judgment and a plea to the jurisdiction, both of which were granted. Liberally construed and reorganized, Carroll's appellate brief raises three types of complaints concerning the trial court's rulings: (1) dismissal after the trial court determined it lacked jurisdiction; (2) denial of due process and due course of law; and (3) judicial impropriety. CC Maple did not file a response. We affirm in this memorandum opinion. See Tex. R. App. P. 47.4.

The trial court granted CC Maple's plea to the jurisdiction and no-evidence motion for summary judgment. Carroll, who appears pro se, argues that "In making a ruling in a setting which [the trial court judge] stated she had no jurisdiction, she violated due process." Carroll also cites the Texas Constitution and argues the trial court denied her due process and due course of law when it dismissed her claims despite lacking jurisdiction to reach the merits.

Courts, however, "always have jurisdiction to determine their own jurisdiction." Heckman v. Williamson County, 369 S.W.3d 137, 146 n.14 (Tex. 2012). "Without jurisdiction the court cannot proceed at all in any cause." Fin. Comm'n of Tex. v. Norwood, 418 S.W.3d 566, 578 (Tex. 2013). Thus, trial courts must determine whether they have the constitutional or statutory authority to decide a case at the earliest opportunity. Tex. Dep't of Parks & Wildlife v. Miranda, 133 S.W.3d 217, 226 (Tex. 2004). Contrary to Carroll's contention, trial courts must dismiss cases when they lack jurisdiction. See Just Energy Texas I Corp. v. Texas Workforce Comm'n, 472 S.W.3d 437, 444 (Tex. App.-Dallas 2015, no pet.). Here, the trial court dismissed Carroll's case after determining it lacked jurisdiction and Carroll did not challenge the propriety of the trial court's determination on appeal. See Tex. R. App. P. 38.1 (f) & (i). Thus, we overrule Carroll's first reorganized issue.

In her second reorganized issue, Carroll argues the trial court deprived her of due process and due course of law when it dismissed her case based on its conclusion that it lacked jurisdiction. We disagree because courts must dismiss cases when they lack jurisdiction. See Just Energy Texas I Corp., 472 S.W.3d at 444. Without citations to authorities and facts, we decline to hold that courts dismissing cases based on the absence of jurisdiction violate due process or due course of law protections when they do so. See Tex. R. App. P. 38.1 (g) & (i). We overrule Carroll's second reorganized issue.

Finally, Carroll (1) challenges the trial court's conduct as improperly partial and prejudiced and (2) accuses the trial court of participating in ex parte communications by speaking about her with opposing counsel "in a negative manner." A thorough review of Carroll's brief, however, reveals no citation to any evidence in the record that supports either of Carroll's complaints. See Tex. R. App. P. 38.1(g). Furthermore, our review of the record reveals no evidence of improperly partial or prejudicial statements and no evidence of ex parte communications. Thus, we overrule Carroll's reorganized third issue.

Having overruled Carroll's issues on appeal, we affirm the judgment of the trial court.
