Texas Code of Criminal Procedure - CRIM P Art. § 46B.004. Raising Issue of Incompetency to Stand Trial

(a) Either party may suggest by motion, or the trial court may suggest on its own motion, that the defendant may be incompetent to stand trial. A motion suggesting that the defendant may be incompetent to stand trial may be supported by affidavits setting out the facts on which the suggestion is made.

(b) If evidence suggesting the defendant may be incompetent to stand trial comes to the attention of the court, the court on its own motion shall suggest that the defendant may be incompetent to stand trial.

(c) On suggestion that the defendant may be incompetent to stand trial, the court shall determine by informal inquiry whether there is some evidence from any source that would support a finding that the defendant may be incompetent to stand trial.

(c-1) A suggestion of incompetency is the threshold requirement for an informal inquiry under Subsection (c) and may consist solely of a representation from any credible source that the defendant may be incompetent. A further evidentiary showing is not required to initiate the inquiry, and the court is not required to have a bona fide doubt about the competency of the defendant. Evidence suggesting the need for an informal inquiry may be based on observations made in relation to one or more of the factors described by Article 46B.024 or on any other indication that the defendant is incompetent within the meaning of Article 46B.003.

(d) If the court determines there is evidence to support a finding of incompetency, the court, except as provided by Subsection (e) and Article 46B.005(d), shall stay all other proceedings in the case.

(e) At any time during the proceedings under this chapter after the issue of the defendant's incompetency to stand trial is first raised, the court on the motion of the attorney representing the state may dismiss all charges pending against the defendant, regardless of whether there is any evidence to support a finding of the defendant's incompetency under Subsection (d) or whether the court has made a finding of incompetency under this chapter. If the court dismisses the charges against the defendant, the court may not continue the proceedings under this chapter, except that, if there is evidence to support a finding of the defendant's incompetency under Subsection (d), the court may proceed under Subchapter F.  1 If the court does not elect to proceed under Subchapter F, the court shall discharge the defendant.
