NUMBER 13-19-00560-CR

COURT OF APPEALS

THIRTEENTH DISTRICT OF TEXAS

CORPUS CHRISTI - EDINBURG

IN RE RENE RIVAS JR.

On Petition for Writ of Mandamus.

MEMORANDUM OPINION

Before Chief Justice Contreras and Justices Hinojosa and Tijerina

Memorandum Opinion by Justice Hinojosa1

On November 4, 2019, relator Rene Rivas Jr., proceeding pro se, filed a petition 

for writ of mandamus through which he seeks to compel the trial court to perform DNA 

testing on biological material. See TEX. CODE CRIM. PROC. ANN. art. 64.01.2 Relator 

 1 See TEX. R. APP. P. 52.8(d) (“When denying relief, the court may hand down an opinion but is not 

required to do so.”); see also id. R. 47.4 (distinguishing opinions and memorandum opinions).

2 Relator has previously raised this issue through both appeal and original proceeding. See, e.g., 

Rivas v. State, No. 13-16-00414-CR, 2017 WL 1228914, at *1 (Tex. App.—Corpus Christi–Edinburg Mar. 

2, 2017, pet. ref'd) (mem. op., not designated for publication); In re Rivas, No. 13-16-00320-CR, 2016 WL 

3911247, at *1 (Tex. App.—Corpus Christi July 11, 2016, orig. proceeding) (mem. op., per curiam).

contends that the failure to perform testing on various items, including a black dress, knife, 

and bedsheets, resulted in his wrongful conviction for sexual assault.

To be entitled to mandamus relief, the relator must establish both that he has no 

adequate remedy at law to redress his alleged harm, and that what he seeks to compel 

is a purely ministerial act not involving a discretionary or judicial decision. In re Harris, 

491 S.W.3d 332, 334 (Tex. Crim. App. 2016) (orig. proceeding); In re McCann, 422 

S.W.3d 701, 704 (Tex. Crim. App. 2013) (orig. proceeding). If the relator fails to meet 

both requirements, then the petition for writ of mandamus should be denied. State ex rel. 

Young v. Sixth Jud. Dist. Ct. of Apps. at Texarkana, 236 S.W.3d 207, 210 (Tex. Crim. 

App. 2007). 

It is the relator’s burden to properly request and show entitlement to mandamus 

relief. Barnes v. State, 832 S.W.2d 424, 426 (Tex. App.—Houston [1st Dist.] 1992, orig. 

proceeding) (“Even a pro se applicant for a writ of mandamus must show himself entitled 

to the extraordinary relief he seeks.”). In addition to other requirements, the relator must 

include a statement of facts supported by citations to “competent evidence included in the 

appendix or record” and must also provide “a clear and concise argument for the 

contentions made, with appropriate citations to authorities and to the appendix or record.” 

See generally TEX. R. APP. P. 52.3. As the party seeking relief, the relator has the burden 

of providing the Court with a sufficient mandamus record to establish his right to a writ of 

mandamus. Lizcano v. Chatham, 416 S.W.3d 862, 863 (Tex. Crim. App. 2011) (orig. 

proceeding) (Alcala, J. concurring); Walker, 827 S.W.2d at 837; see TEX. R. APP. P.

52.3(k) (specifying the required contents for the appendix); R. 52.7(a) (specifying the 

required contents for the record).

In this case, the relator has failed to provide a sufficient appendix or record in 

support of his petition for writ of mandamus and he has therefore failed to meet his burden 

to obtain relief. See Walker, 827 S.W.2d at 837; see generally TEX. R. APP. P. 52.3. 

Moreover, while a trial court has a ministerial duty to rule upon a motion that is properly 

and timely presented to it for a ruling, it generally has no ministerial duty to rule a certain 

way on that motion. In re State ex rel. Young v. Sixth Jud. Dist. Ct. of Appeals at 

Texarkana, 236 S.W.3d 207, 210 (Tex. Crim. App. 2007) (orig. proceeding); In re 

Mendoza, 467 S.W.3d 76, 78 (Tex. App.—Houston [1st Dist.] 2015, orig. proceeding). 

Accordingly, we deny the petition for writ of mandamus. See In re Harris, 491 S.W.3d at 

334; In re McCann, 422 S.W.3d at 704.
