EX PARTE Sean MCNAMARA
From the 198th Judicial District Court, Kerr County, Texas
Trial Court No. B94161 & B94196

Opinion by: Rebeca C. Martinez, Chief Justice

Delivered and Filed: May 13, 2026
AFFIRMED
Appellant, Sean McNamara, proceeding pro se, appeals from the trial court’s order denying
him relief on his pro se application for a writ of habeas corpus from an order of deferred
adjudication on two counts of aggravated sexual assault of child and a judgment on a plea of guilty
on one count of indecency with a child by exposure. See TEX. CODE CRIM. PROC. ANN. art. 11.072;
see also TEX. PENAL CODE ANN. §§ 22.021, 21.11. In three issues, which we construe as two,
McNamara argues that the deferred adjudication order is void ab initio because the offense of
aggravated sexual assault of child was categorically ineligible for deferred adjudication and the
trial court erred in applying laches to bar habeas relief because the underlying order and judgment
are legally void. We affirm.

I. BACKGROUND
On July 29, 2025, McNamara filed an application for habeas relief in two trial court cause
numbers. Without holding a hearing, the trial court considered McNamara’s application and
signed findings of fact, which provide:
1. On June 10, 1994, in Cause No. B94-161, Applicant entered a guilty plea to
two counts of aggravated sexual assault of a child and was placed on ten
(10) years deferred adjudication probation;
2. On June 10, 1994, in Cause No. B94-196, Applicant entered a guilty plea to
the offense of indecency with a child by exposure and was placed on ten
(10) years regular probation (including shock probation);
3. Applicant was represented by trial counsel, Mr. Dennis Smith, at the time
of these proceedings;
4. Applicant did not appeal from these judgments;
5. Applicant has not explained the 31-year delay in seeking habeas corpus
relief from these judgments;
6. Applicant’s trial counsel died on August 15, 2014, and is thus unable to
respond to Applicant’s claims of ineffective assistance of counsel;
7. Both prosecutors representing the State in these cases have also since died;
and
8. Applicant’s negligence to assert his claims in a timely manner has caused
prejudice to the State.
The trial court concluded that McNamara’s claims were barred by the doctrine of laches and that
he was manifestly entitled to no relief on his applications in trial court cause numbers B94-161
and B94-196 1. It denied McNamara’s request for habeas relief as frivolous. McNamara timely
appeals.

Because both cases were handled together and McNamara presents the same issues in both appeals, we resolve the
two together in one memorandum opinion.

II. DISCUSSION
A. Applicable Law & Standard of Review
An individual convicted of a felony or misdemeanor may seek habeas “relief from an order
or judgment of conviction ordering community supervision.” TEX. CODE CRIM. PROC. art. 11.072,
§ 1. When a person files a writ application, he “must be, or have been, on community supervision,
and the application must challenge the legal validity of . . . the conviction for which or order in
which community supervision was imposed” or “the conditions of community supervision.” Id.
art. 11.072, § 2(b). The court may deny a habeas application as frivolous “[i]f the court determines
from the face of an application or documents attached to the application that the applicant is
manifestly entitled to no relief . . . .” Id. art. 11.072, § 7(a).
We review the trial court’s decision to deny habeas corpus relief for an abuse of discretion.
Kniatt v. State, 206 S.W.3d 657, 664 (Tex. Crim. App. 2006). We review de novo pure questions
of law and application-of-law-to-fact questions that do not turn on credibility and demeanor. Ex
parte Beck, 541 S.W.3d 846, 852 (Tex. Crim. App. 2017).
B. Analysis
In McNamara’s first issue, he contends the two orders placing him on community
supervision (probation) were void ab initio because he was statutorily ineligible for such a
disposition. In Ex parte Williams, 65 S.W.3d 656 (Tex. Crim. App. 2001), referenced by the State,
a defendant was convicted of aggravated assault. The trial court entered a deadly weapon finding
in the judgment suspending the defendant’s sentence and placing him on community supervision.
Id. at 657. The trial court later revoked the defendant’s community supervision. Id. The
defendant sought a post-conviction application for writ of habeas corpus under article 11.07 of the
Texas Code of Criminal Procedure. Id. He asserted that the illegal probation order rendered his
-3-

sentence illegal. Id. The Texas Court of Criminal Appeals explained that “community supervision
is not a sentence or even a part of a sentence.” Id. (quoting Speth v. State, 6 S.W.3d 530, 532 (Tex.
Crim. App. 1999)). Additionally, it held that the unlawful grant of probation did not entitle the
applicant to habeas relief. Id. at 658. McNamara’s argument is no different than the applicant’s
argument in Williams. We overrule McNamara’s first issue.
In McNamara’s second issue, he contends the trial court erred in applying laches to bar
habeas relief because the underlying order and judgment are legally void. McNamara specifically
argues:
The trial court’s finding of prejudice — based on the deaths of the attorneys — is
legally insufficient. A challenge to a void judgment based on a facial jurisdictional
defect requires no factual development. It is resolved by examining the judgment
itself and the controlling law. The “prejudice” from deceased witnesses is a red
herring; this case requires no witness testimony. The truth is found in the black-
letter law and the court’s own record. The State is not prejudiced by being stripped
of a conviction it was never entitled to have.
Thus, McNamara’s argument on laches presupposes him prevailing on his first issue. Accordingly,
we overrule McNamara’s second issue.
In closing, we note that McNamara attached to his opening brief in each appellate cause
number an “Affidavit of Sean McNamara in Support of Appellant’s Brief.” These affidavits
purport to raise seven grounds for why McNamara is entitled to habeas relief. These grounds
repeat the theme of McNamara’s first issue. None reference the appellate record. For example,
the seventh ground provides:
g. Ground Seven: Systemic Corruption Rendering Judgments Void.
Proceedings conducted by a court acting without constitutional or statutory
authority are void ab initio. Ex parte Siebold. 100 U.S. 371. 376 (1879). By
imposing a sentence expressly forbidden by the Texas Legislature, the trial court
acted without jurisdiction, and its judgment is a void legal nullity, regardless of any
other judicial misconduct. Aguilar v. State. 810 S.W.2d 318, 320 (Tex. Crim. App.
1993).

These arguments are subsumed by McNamara’s first issue, which we have already addressed.
Relatedly, after the State filed its brief, McNamara filed a “supplemental” appellant’s brief.
McNamara’s “supplemental” brief rehashes some of the arguments in his affidavit and makes some
new contentions. We liberally construe McNamara’s “supplemental” brief as a reply brief.
However, we are prohibited from considering issues raised for the first time in a reply brief. See
Ex parte Munoz, 139 S.W.3d 349, 352 (Tex. App.—San Antonio 2004, no pet.) (providing that “a
reply brief is not intended to allow an appellant to raise new issues.”).
III. CONCLUSION
The trial court’s order denying habeas relief is affirmed. 2
