OPINION
Aрpellant, John K. Lockard, appeals his conviction for murder and resulting ninety-seven-year sentence. On appeal, he complains that the trial court violated his rights to due process and due course of law by refusing to answer a jury question regarding consequences of a verdict of not guilty by reason of insanity. We will affirm.
Factual and Procedural History
On March 1, 2008, appellant called 911 to report that he had shot his ninety-four-year-old grandfather in the head with a shotgun. Appellant raised the defense of insanity at his murder trial. The jury heard evidence that, as appellant grew into an adult, he began to display erratic, unusual behavior and that, in the days preceding the shooting, he had become increasingly paranoid and delusional. In fact, his mother testified that, on the morning of the shooting, he had displayed strange, confused behаvior. Appellant presented evidence that he had been diagnosed with psychotic disorder. The jury also heard evidence concerning the history of mental illness in appellant’s family. Appellant testified that he had not slept the night before the shooting and, at the time of the shooting, felt as though he were in a dream-like, disconnected state of mind in which his memories are disjointed and blurred.
About one-half hour after the jury heard all the evidence and retired to deliberate, it sent a note out to the trial court, asking as follows: “[T]he Jury would like to inquire as to the disposition of Mr. Lockard if we find him not guilty by reason of insanity, if possible.” The trial court responded as follows: “Members of the jury, I cannot answer the question that you’ve asked other than to refer you to the Court’s Charge.” Defense counsel acknоwledged the statutory basis for the trial court’s refusal to provide the jury with the substantive law on disposition in the event the jury found appellant not guilty by reason of insanity, but he lodged an objection that the governing provision denied appellant due process and due cоurse of law. The trial court overruled appellant’s objection, and the jury deliberated two more hours before returning its guilty verdict.
On appeal, appellant reiterates his position. He advances his position in one issue: whether appellant was denied due process and due course of law when the trial court refused to answer the jury’s note with substantive law regarding the civil commitment procedures to be followed in the event the jury returned a verdict of not guilty by reason of insanity.
Standard of Review and Applicable Law
Due Process and Due Course of Law Challenges
We review the constitutionality of a criminal statute
de novo
as a question of
*922
law.
See Owens v. State,
Due process requires only that the most basic procedural safeguards are observed.
Patterson v. New York,
Disposition of Appellant Upon Verdict of Not Guilty by Reason of Insanity
The Texas Code of Criminal Procedure provides very specific procedures to be followed in the event a defendant is found not guilty by rеason of insanity. See Tex. Code Crim. Proo. Ann. arts. 46C.155-.270 (West 2007). Article 46C.154, however, prohibits disclosure of these procedures to the jury:
The court, the attorney representing the state, or the attorney for the defendant may not inform a juror or a prospective juror of the consequences to the defendant if a verdict of not guilty by reason of insanity is returned.
Id. art. 46C.154 (West 2007).
Though appellant appears to challenge the propriety of the trial court’s refusal to provide the jury with the substantive law regarding disposition in the event of a verdict оf not guilty by reason of insanity, he seemingly acknowledges that the trial court’s response to the jury’s question was governed and limited by article 46C.154. His contentions on appeal focus, instead, on a challenge to the constitutionality of article 46C.154 as it applies here when it prohibited the trial court from issuing a supplemental charge in response to the jury’s question. As we read appellant’s issue, he complains that, by precluding the trial court’s supplemental instruction regarding disposition upon a finding of not guilty by reason of insanity, articlе 46C.154 operated to deny appellant’s rights to due process and due course of law.
*923 Prior Constitutional Challenges
Article 46C.154’s predecessor
1
withstood similar challenges, most notably in
Robison v. State,
In
Zwack,
the appellant attacked the constitutionality of that portion of former article 46.03 which, like article 46C.154, prohibited the trial court, prosecutor, and defense counsel from informing a juror or prospective juror of the consequences to the accused if a verdict of not guilty by reason of insanity is returned.
See Zwack,
In addressing appellant’s contentions, the
Zwack
court first noted that it was unable to “discern any constitutional infirmity in the statute” and that Zwack had “not supрorted his contention with convincing argument.”
Id.
The court went on to observe that, even before the enactment of the provision at issue, Texas courts have consistently held that the statutes prescribing the disposition of a defendant found not guilty by reason of insanity arе “a guideline for the court and not for the jury’s consideration.”
Id.

The
Zwack
court continued, distinguishing the basis for the
Lyles
decision: “[T]he rule announced by the District of Columbia Circuit Court of Appeals in
Lyles
was not based upon constitutional principles but upon its rule-making authority.”
See Zwack,
About six years later, the Texas Court of Criminal Appeals addressed the same contention.
See Robison,
*924
Like Zwack, Robison urged the Texas Court of Criminal Appeals to adopt the rationale of
Lyles. Robison,
Dealing again with a challenge to article 46C.154’s predecessor, the Texas Court of Criminal Appeals briefly revisited the issue a few years later only to reaffirm — and arguably clarify — its holdings in Robison:
The Texas Legislature has clearly stated that no party, including the trial court, may inform a juror or a prospective juror of the consequences to the defendant if a verdict of not guilty by reason of insanity is returned. In denying similar contentions from other appellants, we have held that Article 46.03, § 1(e), does not violate the Constitution and that informing the jury of the consequences of finding a defendant not guilty by reason of insanity is a policy matter exclusively within the purview of’ the Legislature.
Moore v. State,
Nature of Appellant’s Issue on Appeal
When the trial court responds substantively to a question the jury asks during deliberations, that communication essentially amounts to a supplemental jury instruction, and the trial court must follow the same rules for impartiality and neutrality that generally govern jury instructions.
Lucio v. State,
Analysis
We are persuaded and bound by
Zwack
and
Robison,
respectively. To the extent
Robison
addressed the issues raised in the instant appeal, we are “bound by the
*925
precedent of the Texas Court of Criminal Appeals and [have] no authority to disregard or overrule” it.
See Bolen v. State,
However,
Robison
does touch on an issue central to the constitutional issues raised here: “[W]e fail to see where the policy decisions of our sister courts throughout the union are ever raised to the level of a due process right or a due course of law right.”
Robison,
Further, we find guidance from both
Zwack’s
and
Robison’s
dеference to the Legislature on this matter: should there be the need or call for a change in the policy on this particular issue, that change should be analyzed and implemented by the Legislature, if at all.
See Robison,
Conclusion
Having overruled appellant’s issue, we affirm the trial court’s judgment of conviction.
Notes
. Article 46C.154’s predecessor, articlе 46.03, section 1(e), similarly provided as follows:
The court, the attorney for the state, or the attorney for the defense may not inform a juror or a prospective juror of the consequences to the defendant if a verdict of not guilty by reason of insanity is returned.
. Citing
Holder v. State,
.Although thе Texas Court of Criminal Appeals did not engage in an extensive analysis of Robison's contentions in terms of constitutional rights, the same defendant later brought a federal habeas corpus proceeding raising the same constitutional challenge.
See Robison v. Johnson,
. Further, we note that
Zwack
specifically dealt with "the failure of the trial court to answer an inquiry from the jury as to the consequences” of a verdict of not guilty by reason of insanity.
Zwack,
. Further, as we have noted, it would appear the Texas Court of Criminal Appeals itself has read
Robison
to, at a minimum, have a bearing on constitutional issues.
See Moore, 999
S.W.2d at 404-05;
Bigby v. State,
. In fact, we note that article 46C.154 and the trial court’s adherence to it here are consistent with the recognized notion that a jury should not be concerned with the consequence of its verdict.
