delivered the opinion of the Court.
In this original proceeding, Justice Errl-inda Castillo of the Thirteenth Court of Appeals seeks writs of mandamus and prohibition ordering the Thirteenth Court to vacate an exit plan devised for her by the other justices of that court after Justice Castillo lost her reelection bid. We deny the petitions.
In November 2000, Justice Castillo was elected as a justice of the Thirteenth Court of Appeals for a term running from January 1, 2001 through Deсember 31, 2006. Although she sought election to a second term, she lost her reelection bid to a challenger in the Democratic Party primary on March 7, 2006. Shortly thereafter, on April 6, 2006, the Thirteenth Court held a judges’ meeting which Justice Castillo did not attend. In her absence, the court decided that, after May 31, 2006, Justice Castillo would not be assigned to the court’s panels

to hear appeals; instead, a visiting judge would sit in her place. As a
Justice Castillo filed a petition seeking writs of mandamus and prohibition, asking that we: (1) prohibit the Thirteenth Court from excluding her from case assignments after May 31, 2006; (2) order the court to permit her to draw for panel and writing assignments; and (3) prohibit the court from assigning a visiting judge in her place. She argued that the exit plan infringed on her right to complete her term as justice on the court of appeals and, in doing so, violated the Texas Constitution, state statutes, and the court of appеals’ administrative rules.
After Justice Castillo filed her petition, the Thirteenth Court held another meeting, this one attended by Justice Castillo. At this May 3 meeting, the court rescinded the April 6 plan and implemented a modified еxit plan. 2 Under the modified plan, Justice Castillo would participate in the draw for panel assignments for the summer and fall terms and would be eligible to draw for majority-opinion assignments for the summer term. The court withdrеw its request for the assignment of a visiting judge to serve in Justice Castillo’s place. Beginning in the fall term, however, neither Justice Castillo nor Justice Hinojosa 3 would be assigned initial responsibility for drafting majority opinions. According to the Thirteenth Court, Justice Castillo’s exclusion was necessary because she was allegedly thirty-eight cases behind on her work. Justice Castillo hotly disputed this contention, noting that the thirty-eight matters assigned to her are a “docket of current cases.” Justice Castillo asserted that, as of June 2, 2006, she had a docket of no more than eleven current cases that she expected to “zero out” by August 31, 2006.
As additional support for the modified plan, the court observed that Justice Castillo’s remaining tenure on the court involved significantly less time than the approximately seven months it normally takes the court to issue an opiniоn in a civil case. Nonetheless, the court decided that if Justice Castillo completed her work by the end of the summer term on August 31, she would be assigned more work on an ad hoc basis. The court then drew for pаnel assignments for the summer and fall terms and Justice Castillo was randomly assigned to Panel B for the summer term and Panel A for the fall. 4
After modifying the exit plan, the Thirteenth Court moved to dismiss Justice Castillo’s petition without prejudice, contending, among other things, that she could not establish that the new plan violated any constitutional provision, statute, or administrative rule. Justice Castillo
This Court has a constitutional obligation to supervise and administer the judicial branch. Tex. Const, art. V, §§ 3, 31. Pursuant to this obligation, we “have supervisory and administrative control over the judicial branch and [are] responsible for the orderly and efficient administration of justice.” Tex. Gov’t Code § 74.021. We also have inherent power to protect and preserve the proper administration of the judicial system.
Vondy v. Comm’ns Court of Uvalde County,
The actions taken at the May 3 judges’ meeting, and the resulting exit plan, moot many of Justice Castillo’s original complaints. The Thirteenth Court now correctly agrees that Justice Castillo, like every other justice on the court, may vote on сases heard by her panel; draft concurring or dissenting opinions in any cause in which she participated in the decision; vote on motions for rehearing; participate in oral argument; particiрate in original proceedings and motions; and discuss cases with her fellow justices. The court also concedes, appropriately, that Justice Castillo is entitled to write proposed majority оpinions which, if joined by another justice, would become the opinion of the court.
The modified plan does, however, alter Justice Castillo’s role on the court in that she has been excluded from the initiаl majority-opinion assignment draw for the fall term. Justice Castillo contends, therefore, that the modified exit plan violates article V, section 6 of the Texas Constitution, which establishes courts of appеals and authorizes them to “sit in sections as authorized by law.” Tex. Const, art. V, § 6. In addition, Justice Castillo asserts that the modified exit plan contravenes section 22.222(b) of the Government Code, which provides:
If more than one panel is used, the court of appeals shall establish rules to periodically rotate the justices among the panels. Permanent civil panels and criminal panels without rotation may not be established.
Tex. Gov’t Code § 22.222(b). While these provisions themselves do not grant Justice Castillo the right to be included in the majority-opinion assignment draw, she urges that when combined with the Thirteenth Court’s administrative rules, her entitlement to be assigned majority opinions becomes clear.
Administrative Rule 4 provides, in relevant part, that:
Panels will be chosen so that the memberships will be known for two three month terms, i.e., the current term and the next. At the beginning of each term, the Justices will draw for membership on the panels for the next term.
Cases shall be assigned to the panels as set forth in Rule 6.
Administrative Rule 6(B) provides, in relevant part:
All Justices, without exception, shall ... randomly draw for panel membership. After panel membership is so chоsen, seniority on the panel shall be determined. The Justices shall then randomly draw writing assignments.
We disagree that these rules establish a right for a justice to be assigned initial drafting responsibility for majority opinions. While Rule 6 рrovides that “Justices” will randomly draw writing assignments, the rule neither states that “all Justices” shall draw 5 nor that its provisions may not be temporarily suspended. It appears, in fact, that the rules themselves contemplate just such a suspension. See 13th Court Administrative Rule 24 (providing that “[b]y majority vote of the Court en banc, these rules may be amended or temporarily suspended”). The Thirteenth Court employed this practice at the May 3 meeting. Although the mоdified plan itself may not be the most prudent model for a court endeavoring to clear its docket, we conclude that the court acted within its discretion in adopting it.
Both state and federal apрellate courts engage in a variety of practices for assigning cases and managing their dockets. Some assign cases randomly, others by seniority, still others by assignment of the chief justice.
See, e.g.,
Melinda Gann Hall,
Opinion Assignment Proсedures and Conference Practices in State Supreme Courts,
73 JudicatuRE 209, 210-11 (1990); Sandra Day O’Connor,
Remembering Rehnquist,
31 JouRnal Of Supreme CouRT History 5, 7 (2006). Courts must have some leeway in making such assignments to help maintain a current docket. Whether we deem the modified plan at issue here advisable or not, we must leave it to the Thirteenth Court to determine whether such a plan will maximize efficiency when faced with one (and possibly two) outgoing justices during the last few months of thеir terms. While there may be circumstances in which a court’s suspension of its internal rules constitutes a clear abuse of discretion, it does not appear, under the circumstances presented herе, that the Thirteenth Court clearly abused its discretion or refused to perform a non-discretionary duty.
See In re Yates,
It is not uncommon for justices on a collegial court to harbor differences of opinion on administrative or substantive matters. Proceedings like these are rare but may occasionally be necessary to ensure that a justice is able to perform the duties appertaining to the office.
