The Informal-Inquiry Threshold
When 'Some Evidence' Forces a Texas Competency Inquiry
In Texas, once any credible source suggests a defendant may be incompetent, the judge must stop and conduct an informal inquiry. The trigger is deliberately low: some evidence, more than a scintilla and from any source, that the defendant cannot understand the proceedings or help counsel. No bona fide doubt is required, and the court considers only evidence of incompetency.

What Triggers a Texas Competency Informal Inquiry?
A Texas competency inquiry begins with a suggestion — a representation from any credible source that the defendant may be incompetent. Under article 46B.004, either party may raise it by motion or the judge may raise it on the court’s own motion, and when such evidence reaches the court the judge must begin an informal inquiry.
The statute is structured in steps. Under article 46B.004(a), either party may suggest by motion that the defendant may be incompetent, and the motion may be supported by affidavits setting out the underlying facts. Under 46B.004(b), if evidence suggesting incompetency comes to the court’s attention from any source, the judge on the court’s own motion “shall” suggest that the defendant may be incompetent. The word “shall” matters: this is a duty, not a discretionary courtesy. A judge who sees the trigger cannot look away simply because neither lawyer filed a motion.
Article 46B.004(c-1) sets the threshold as low as the Legislature could reasonably make it. A suggestion of incompetency “may consist solely of a representation from any credible source that the defendant may be incompetent.” The statute adds that “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.” In other words, the front door to a competency inquiry is wide. Defense counsel’s own representation, a jailer’s observation, a treating clinician’s note, or the judge’s courtroom observations can each be enough to start the process.
The suggestion is intentionally easier to make than the formal motion that gives this practice area its name. A written motion suggesting incompetency, supported by affidavits from counsel, family, or a clinician, is the most common and most durable way to put the issue before the court, because it builds a record. But nothing in article 46B.004 requires that formality. An oral representation in open court, a letter from a jail’s mental-health unit, or the judge’s own observation can each supply the suggestion. What the statute cares about is that credible information reaches the court; the packaging is secondary.
How Much Is 'Some Evidence'?
Once a suggestion is made, article 46B.004(c) tells the judge to determine by informal inquiry whether there is “some evidence from any source that would support a finding that the defendant may be incompetent.” The Court of Criminal Appeals has defined that phrase precisely, and it sits well below the standard a defendant must ultimately meet.
In Turner v. State, the court described the statutory “some evidence” standard as requiring “more than none or a scintilla” of evidence that “rationally may lead to a conclusion of incompetency.” The court in Boyett v. State called this “not a particularly onerous” burden. It is a screening question, not a verdict. The judge is not deciding whether the defendant is in fact incompetent — only whether enough exists to justify a formal examination and, if appropriate, a trial.
It helps to see the three thresholds side by side. Each does a different job at a different stage, and confusing them is a common error.
| Standard | What it asks | Where it applies |
|---|---|---|
| Suggestion (art. 46B.004(c-1)) | A representation from any credible source that the defendant may be incompetent | Threshold to start the informal inquiry |
| Some evidence (art. 46B.004(c)) | More than none or a scintilla, from any source, that rationally may lead to a conclusion of incompetency | Whether to order an examination and hold a formal trial |
| Preponderance (art. 46B.003(b)) | More likely than not that the defendant is incompetent | The ultimate finding at the formal competency trial |
Because the informal-inquiry bar is so much lower than the preponderance standard that governs the eventual trial, evidence that would never carry the day before a jury can still be more than enough to open the door to an examination.
Keeping the standard this low is a deliberate protection. Because the consequence of wrongly proceeding — trying a person who cannot understand or participate — is so serious, the Legislature set the screening bar where even a modest showing forces a closer look. The cost of an unnecessary examination is comparatively small; the cost of skipping a needed one can be a conviction obtained in violation of due process. The some-evidence threshold reflects that asymmetry.
Why the Judge Ignores Evidence of Competency at This Stage
A rule that surprises many first-time observers governs how the judge sizes up the record: at the informal-inquiry stage the court looks at only one side of the ledger. It must consider only evidence tending to show incompetency and may not weigh competency evidence against it. This one-way review is what keeps the threshold meaningful.
The Court of Criminal Appeals stated the rule plainly in Boyett: “a trial court must consider only evidence of incompetency, and it must not weigh evidence of competency against the evidence of incompetency.” The court drew that directly from Turner, which instructed judges to put “aside all competing indications of competency” and ask whether there is more than a scintilla that rationally may lead to a conclusion of incompetency. In Turner itself, the trial court had made the classic mistake — it focused on the experts’ ultimate conclusions that the defendant was competent rather than on the evidence pointing the other way — and the appellate court held that this was error.
The logic is structural. If a judge could defeat a competency inquiry simply by pointing to countervailing proof of competency, the inquiry would collapse into a premature mini-trial decided by the judge alone. By restricting the informal inquiry to evidence of incompetency, Texas law reserves the actual weighing of both sides for the formal competency trial, where the fact-finder decides the question under the preponderance standard. A defendant does not have to win the issue at the informal-inquiry stage; the defendant only has to show that a genuine question exists.
The rule cuts against a natural judicial instinct. A judge who has just read an expert report concluding the defendant is competent will be tempted to end the matter there. But the some-evidence question is not which opinion is more persuasive; it is whether any credible evidence of incompetency exists. Even a single qualified opinion, or a compelling lay account, can require the next step notwithstanding contrary expert conclusions. Turner arose exactly this way — the trial court leaned on experts’ bottom-line competency findings, and the Court of Criminal Appeals held that doing so put the analysis backward.
What Counts as Evidence, and Where It Comes From
Because the statute accepts evidence “from any source,” the material that can trigger and support an inquiry is broad. It is anchored to the substantive test for incompetency, which asks about the defendant’s present mental capacity, and it can include lay observations as readily as clinical opinions.
The substantive standard comes from article 46B.003(a), which codifies the constitutional test announced in Dusky v. United States. A defendant is incompetent if he lacks either sufficient present ability to consult with counsel with a reasonable degree of rational understanding, or a rational as well as factual understanding of the proceedings. Article 46B.003(b) then presumes every defendant competent unless proven otherwise by a preponderance. The word “present” is the key — competency is about the defendant’s condition now, during the case, not his mental state at the time of the offense.
Article 46B.004 itself notes that evidence suggesting the need for an inquiry may rest on observations tied to the examination factors listed in article 46B.024 or on any other indication of incompetency. In Boyett, the Court of Criminal Appeals confirmed that lay opinions about competency may suffice as some evidence and should not be brushed aside just because the witness is not a mental-health professional. In practice, the raw material often includes a defendant’s incoherent or delusional statements in court, records of recent severe mental illness or intellectual disability, hospitalization or medication history, and counsel’s firsthand account of an inability to communicate about the case.
| Type of source | Examples that may raise the issue |
|---|---|
| Counsel | An attorney’s representation that the client cannot rationally discuss the charges or assist in the defense |
| Lay witnesses | Family members, jail staff, or bystanders describing bizarre conduct or confusion |
| Records | Recent psychiatric hospitalization, intellectual-disability diagnoses, or medication regimens |
| The court’s own observations | Delusional, nonresponsive, or disoriented behavior during proceedings |
Mental Illness, Refusal to Cooperate, and the 'Engine of Obstinacy'
Not every difficult defendant is an incompetent one. Texas law draws a careful line: mental illness alone does not establish incompetency, and neither does a stubborn refusal to cooperate with counsel. What matters is whether the illness is what drives the inability to work with the defense in a rational way.
In Turner, the Court of Criminal Appeals explained that a defendant may be mentally ill yet competent, and may even refuse to cooperate with counsel yet still be competent, so long as the manifestations of the illness are not the reason for the refusal. But when a defendant’s mental illness “operates in such a way as to prevent him from rationally understanding the proceedings against him or engaging rationally with counsel,” he cannot be tried consistent with due process. The court framed the required showing as a three-part inference, later restated in Boyett: there must be some evidence that the defendant (1) suffers some degree of debilitating mental illness, (2) obstinately refuses to cooperate with counsel to his own apparent detriment, and (3) does so because that mental illness is the engine of his obstinacy.
This matters at the threshold because it tells counsel what the record needs to reflect. Evidence of a diagnosis, standing alone, may not connect the illness to the defendant’s capacity to assist. Evidence of refusal to cooperate, standing alone, may look like ordinary defiance. The persuasive presentation links the two — showing, for example, that a defendant’s paranoid delusions about his own attorney are what make rational collaboration impossible. When that link is present, even in modest form, the some-evidence threshold is satisfied.
Courts applying this framework look for the causal link in the specifics. Delusions that fixate on defense counsel, a thought disorder that prevents the defendant from tracking a conversation about the charges, or a cognitive impairment that blocks understanding of a plea offer are the kinds of facts that tie the illness to the incapacity. General agitation, a personality clash with counsel, or a considered decision to stonewall — without more — do not.
From Informal Inquiry to Examination and Trial
The informal inquiry is a gateway, not a destination. If the judge finds some evidence of incompetency, the case shifts into the formal track: proceedings are stayed, an expert examination is ordered, and a competency trial follows unless the parties and the court all decline one. The duty to watch for incompetency then continues for the life of the case.
Under article 46B.004(d), once the court determines that evidence supports a finding of incompetency, it must, with narrow exceptions, stay all other proceedings. Article 46B.005(a) then requires the court to order an examination under Subchapter B, and 46B.005(b) requires a trial under Subchapter C before the incompetency question is resolved — except that, under 46B.005(c), no trial is required if neither party’s counsel requests one, neither opposes a finding of incompetency, and the court does not on its own motion decide a trial is necessary. The companion pages in this guide walk through the expert appointment and the competency trial in detail.
The obligation does not end once the case begins. In Drope v. Missouri, the Supreme Court held that even a defendant who is competent when trial starts must be monitored, because a trial court “must always be alert to circumstances suggesting a change” in competency. And in Pate v. Robinson, the Court held that trying an incompetent defendant violates due process and that where the evidence raises a genuine question the judge must act on his own motion — a defendant cannot knowingly waive a hearing on the very capacity that a waiver would require. Article 46B.005(d) reflects this by allowing the issue to be raised and determined even after the trial on the merits has begun.
When a trial court declines to act, the standard of review on appeal is abuse of discretion, and the reviewing court asks whether the record contained some evidence that should have prompted the next step. Because competency must be assessed as it existed at the time, a belated inquiry can be hard to reconstruct; both Pate and Drope stressed the unreliability of judging competency long after the fact. That timing problem is a practical reason to raise the issue promptly and to build a contemporaneous record rather than hoping to rebuild one later.
