Which Texas Supreme Court petition-response timetable applies?

Establish the actual petition, or first petition, filing date and the January 1, 2026 boundary.

Read any court order changing historical applicability and obtain the response directions.

Select the event under the established edition and determine any actually granted extension.

1. Establish the actual petition, or first petition, filing date and the January 1, 2026 boundary.
2. Exclude the actual triggering event and count every intermediate calendar day under Rule 4.1(a). Do not import the Civil Rules’ short-period exclusion into appellate computation. A signing, rendition, filing or ruling date must be established from its own actual record. The current edition uses the actual response order; the former edition uses petition filing. A single order-date addition without edition selection cannot establish the operative timetable.
3. Apply Rule 4.1 and establish the actual clerk calendar.
4. Complete the required act in the correct court.

Rule 4.1(a) moves a final Saturday, Sunday or legal holiday to the next eligible day. Rule 4.1(b) separately extends a filing period when the proper clerk is closed or inaccessible during regular hours on the final day, until the next open and accessible day. Preserve the required proof. The encoded Texas holiday calendar covers 2026 through 2028; it does not know additional local closure or system failure.

The available calculator does not establish the January 1, 2026 first-petition boundary or a court order changing applicability. It cannot safely choose between the current response-order event and former petition-filing event.

Establish the January 1, 2026 applicability boundary

Misc. Docket No. 25-9104, paragraphs 3–4, applies the amended Supreme Court rules when the petition, or first petition in a multiple-petition case, is filed on or after January 1, 2026. Earlier cases use the former rules unless the Court orders otherwise. This review’s current contents apply only after that edition is established.

Response and reply extensions differ from petition extensions

Rule 53.7(f) permits a Rule 10.5(b) extension motion before or after a response or reply is due. Its fifteen-day-after-deadline restriction for a petition is a different branch. Relief requires the Supreme Court’s decision.

An unsolicited response is not universally required

Rule 53.3 requires no response unless ordered and provides that the petition cannot be granted before a response is filed or ordered. Do not manufacture a response deadline merely from service of the petition.

Response contents have stated differences

Rule 53.3 adapts Rule 53.2, including the introduction, corrections to parties and counsel, disputed facts or case statement, stated additional issues, jurisdiction objections, confined argument and nonduplicative appendix.

Nonconforming documents can affect disposition

Rule 53.9 allows the Court to require revision or return a nonconforming document and consider the case without permitting revision. A filing date does not prove conforming contents.

• The consolidation date does not establish applicability of every historical amendment. Read the actual governing edition and orders.

• File the response with the Supreme Court clerk, following Rule 53.3’s adapted Rule 53.2 contents. Preserve the response order and service confirmation. File with the proper appellate clerk. Under Rule 9.2(c)(4), ordinary electronic filing occurs on transmission to the filing party’s service provider before midnight in the court’s time zone, subject to a specified time of day, weekend or holiday transmission and a required leave order. Attorneys in civil cases must electronically file subject to Rule 9.2(c)’s stated exceptions. Preserve confirmation and seek appropriate court relief for technical failure under 9.2(c)(5). Rule 9.5 separately requires timely service on all parties, ordinarily their lead counsel, and proof of service; appellate records outside original proceedings have their stated service exception. A qualifying mailed filing under 9.2(b) requires timely deposit or delivery and receipt within ten days after the filing deadline. Those ten days do not permit late deposit.
