In re John Henry Garber, 06-26-00033-CR, March 16, 2026.
On appeal from Court of Appeals Sixth Appellate District of Texas at Texarkana, Texas.
Synopsis
The Sixth Court of Appeals summarily denied a petition for writ of mandamus because the relator failed to include the mandatory certification required by Rule 52.3(k) of the Texas Rules of Appellate Procedure. This ruling underscores the appellate courts’ insistence on strict technical compliance in original proceedings, demonstrating that even a potentially meritorious claim will be rejected if the formal requirements for verification are not met.
Relevance to Family Law
In the high-stakes arena of Texas family law, mandamus is often the only vehicle for immediate relief from trial court orders regarding temporary custody, emergency stays, or the exclusion of critical evidence. This case serves as a stark reminder that the “emergency” nature of a family law dispute does not excuse a practitioner from the meticulous requirements of TRAP 52. A petition challenging a trial court’s abuse of discretion in a SAPCR or a high-asset divorce will be discarded without reaching the merits if it lacks the specific, sworn certification that all factual statements are supported by competent evidence in the record. For the family law litigator, a “substantial compliance” approach is a recipe for summary denial and potential exposure to malpractice claims.
Case Summary
Fact Summary
John Henry Garber filed an original proceeding for a writ of mandamus in the Sixth Court of Appeals, seeking to compel the trial court to rule on several motions pending in three separate trial court cases. Despite the potential for a trial court’s failure to rule to constitute an abuse of discretion, Garber’s petition was procedurally deficient. Specifically, the petition did not include the mandatory certification that the relator had reviewed the filing and concluded that every factual statement therein was supported by competent evidence included in the appendix or the record.
Issues Decided
- Does the failure to include the mandatory certification required by Texas Rule of Appellate Procedure 52.3(k) necessitate the denial of a petition for writ of mandamus?
Rules Applied
- Texas Rule of Appellate Procedure 52.3(k): This rule requires the person filing the petition to certify that they have reviewed the petition and concluded that every factual statement is supported by competent evidence in the appendix or record.
- Texas Rule of Appellate Procedure 52.1, 52.3(e), and 52.7: General rules governing the commencement of original proceedings and the required contents and records for such petitions.
- In re Accident Fund Gen. Ins. Co., 543 S.W.3d 750 (Tex. 2017): A per curiam opinion from the Texas Supreme Court affirming that non-compliance with the technical requirements of Rule 52 is sufficient grounds for denying mandamus relief.
- CMH Homes v. Perez, 340 S.W.3d 444 (Tex. 2011): A Texas Supreme Court case emphasizing that while some matters can be remanded to be treated as mandamus, they must fully comply with the Rule 52 requirements upon remand.
Application
The Court’s analysis was concise, focusing exclusively on the procedural threshold for original proceedings. Under TRAP 52.3(k), the relator is burdened with a specific duty to verify the factual basis of their petition against the submitted record. The Court observed that Garber’s petition lacked the exact certification language required by the rule. Because the relator did not certify that he had reviewed the petition and confirmed the factual statements were supported by the evidence in the appendix or record, the Court determined it could not proceed.
Relying on established Texas Supreme Court precedent, the Court treated these procedural requirements not as mere suggestions, but as jurisdictional or quasi-jurisdictional gatekeepers. The Court did not engage in a review of whether the trial court had actually failed to perform a ministerial duty; the lack of a proper certification ended the inquiry immediately.
Holding
The Court held that the petition for writ of mandamus must be denied due to the relator’s failure to comply with the mandatory certification requirements of Texas Rule of Appellate Procedure 52.3(k).
The Court further held that strict adherence to the Texas Rules of Appellate Procedure is a prerequisite for seeking the extraordinary remedy of mandamus, and the absence of a sworn certification verifying the factual allegations is a fatal defect.
Practical Application
For the family law practitioner, this case emphasizes that your appellate clerk or paralegal’s checklist is just as important as your legal argument. When seeking mandamus relief—perhaps to stay an order that drastically alters a possession schedule—the certification must be included and must mirror the rule’s language exactly. Practitioners should ensure that the relator or their counsel actually performs the cross-referencing between the petition’s facts and the appendix documents before signing the certification.
Checklists
Mandatory Certification Audit
- Ensure the petition includes a section or attachment labeled “Certification.”
- Verify the certification uses the verbatim language: “I have reviewed the petition and concluded that every factual statement in the petition is supported by competent evidence included in the appendix or record.”
- Confirm the certification is signed by the relator or the relator’s lead counsel.
- Check that the person signing the certification has personal knowledge of the record to support the statement.
Mandamus Filing Essentials
- Verify that an Appendix is included and contains a certified or sworn copy of the order complained of, or a compliant statement if no order was signed.
- Confirm that a Record is filed concurrently, containing all documents that are part of the trial court record and relevant to the claim.
- Ensure the Record is properly authenticated by a sworn declaration or is a certified copy from the clerk.
- Review the petition for compliance with TRAP 52.3(a)-(j) (Table of Contents, Table of Authorities, Statement of the Case, etc.).

Family Law Crossover
This ruling is a potent weapon for a respondent in a mandamus proceeding. In high-conflict custody or property litigation, an adversary may rush to the court of appeals to stop a trial court’s momentum. Your first strategic move should not be a substantive Response, but a technical audit. If the Relator’s counsel failed to include the TRAP 52.3(k) certification—or if they used “substantial compliance” language rather than the strict wording of the rule—you should immediately highlight this to the Court of Appeals.
In the Sixth Court and many others, this is a “gotcha” that works. By securing a summary denial on procedural grounds, you force the opposing party to start over, potentially causing them to lose critical time or credibility with the appellate court. In the context of a pending trial or a sensitive possession transfer, the delay caused by a procedurally deficient mandamus filing can be the difference between winning and losing the case at the trial level.
