Raising Competency and Who May Raise It
Either party may move, and the court must act on its own motion when the record raises a real doubt about the defendant's capacity. The threshold is deliberately low, the inquiry suspends the criminal case while it runs, and the time consumed is excluded from the speedy trial clock.

The rule in short
Federal law permits the defendant or the government to move for a competency hearing at any time after prosecution begins and before sentencing, and requires the court to order a hearing on its own motion where there is reasonable cause. A trial court that ignores evidence raising a bona fide doubt commits constitutional error. California suspends all criminal proceedings once the inquiry begins, and the resulting delay is excludable under the Speedy Trial Act.
Competency is not an affirmative defense and does not belong to either party. A criminal case cannot proceed against a defendant who cannot take part in it, so the question can be put in issue by the defense, by the prosecution, or by the judge, and once it is properly raised the case stops until it is answered. The threshold for raising it is deliberately low.
Who may put the question in issue
Federal law names both parties. Section 4241 of title 18 permits the defendant or the attorney for the Government to file a motion for a hearing to determine mental competency at any time after the commencement of a prosecution and before sentencing, and again at any time after probation or supervised release begins and before the sentence is complete. Ohio names three sources: the court, the prosecutor or defense counsel. New York places the duty on the court, directing an examination order whenever the court is of the opinion that the defendant may be an incapacitated person.
In practice the issue is raised most often by defense counsel, for the obvious reason that counsel has spent the most time attempting to have the conversation the standard is about. It is raised by prosecutors less frequently, usually where a defendant is preparing to waive counsel, plead guilty or reject an offer in a way the record suggests may not be rational. Defense objection does not foreclose the inquiry. The prohibition on trying a person who cannot participate protects the integrity of the proceeding, and it is not the defendant's to waive.
The threshold and the court's own duty
The federal formulation is reasonable cause to believe the defendant may presently be suffering from a mental disease or defect rendering him mentally incompetent. That is a low bar, and it is framed as a possibility rather than a probability. The constitutional counterpart is stated as a bona fide doubt: the Supreme Court held that a trial court presented with evidence raising a real doubt about competence must conduct an inquiry, and that failing to do so denies due process regardless of whether either party asked.
What creates the doubt is a matter of record rather than of impression. Recurring sources include irrational behavior in court, a demeanor that suggests the defendant is not following the proceeding, a prior medical opinion on the subject, a documented history of psychiatric hospitalization, a known intellectual disability, and counsel's own representation that communication has broken down. No single item is required, and courts have found error where a judge noticed several and proceeded anyway.
| Source | What must be shown | When available | Immediate effect |
|---|---|---|---|
| Defense motion | Reasonable cause | From commencement of prosecution to sentencing | Hearing ordered; examination usually ordered first |
| Government motion | Reasonable cause | Same window | Hearing ordered on the same terms |
| Court on its own motion | Reasonable cause, or a bona fide doubt on the record | Any time the doubt arises | Duty to inquire, independent of the parties |
| Post-sentence supervision | Reasonable cause during probation or supervised release | Before the sentence is complete | Hearing under the same statute |
| State variants | Doubt stated on the record, with counsel's opinion | Before trial or after conviction | All criminal proceedings suspended |
A whispered concern at sidebar and a denial from the bench can leave an appellate court with nothing to review. A written motion attaching the records that generated the doubt, together with counsel's specific account of what communication has failed, puts the evidence in front of the trial court and preserves the constitutional claim if the inquiry is refused. It also gives the examiner something to work from beyond an interview conducted without context.
What suspension actually stops
Once the question is properly raised, the criminal proceeding does not continue. California states it flatly: all proceedings in the criminal prosecution are suspended until the question of present mental competence has been determined, and a sworn jury is discharged if the defendant is found incompetent. Federal practice reaches the same result functionally, since the case cannot move to trial or plea while the inquiry is open.
Suspension is not total, and the line is worth knowing. Matters that do not require the defendant's participation can generally proceed: purely legal motions, scheduling, and in many courts a suppression motion resting entirely on officer testimony. Anything requiring the defendant to make a decision, give instructions or testify cannot. Where a court proposes to hear something during the suspension, the useful question is whether the defendant's capacity is needed for that particular step.
Suspension also affects the defendant's custody status, and not always in the defendant's favor. A case that stops does not release anyone, and in many systems a defendant awaiting an examination or a bed at an evaluating facility remains in local custody the entire time. Some states have addressed this by requiring the evaluating agency to accept a defendant within a fixed number of days; others have no deadline at all, and the waiting period is set by the number of available beds.
The clock and the cost
The delay is excluded from the speedy trial computation. Section 3161 excludes delay resulting from any proceeding, including any examinations, to determine the mental competency or physical capacity of the defendant. A separate provision addresses transportation to and from places of examination or hospitalization, and presumes unreasonable any period beyond ten days between an order directing transportation and the defendant's arrival. That ten-day presumption is one of the few enforceable limits on a process that otherwise runs on institutional timelines.
The cost of raising the question is real and should be stated plainly rather than avoided. The examination takes weeks, the hearing takes longer, and a finding of incompetence produces a commitment measured in months. A defendant held throughout may spend more time in custody on the competency track than the charge itself would ever produce. That is an argument for moving quickly and for pressing the deadlines, not for leaving a genuine question unraised.
The counterweight is that a conviction obtained against a defendant who could not participate is unsound and vulnerable to collateral attack, and the underlying problem does not resolve itself by being ignored. A defendant who cannot follow the proceeding cannot supply the facts that would have changed it, cannot evaluate an offer, and cannot decide whether to testify. Those failures are invisible in a transcript, which is exactly why the duty to inquire is placed on the court rather than left to the parties.
What follows the motion is the court-ordered evaluation, measured against the competency standard, with a defense examination available alongside it and restoration waiting if the finding goes the other way. Each of those steps has its own deadlines, and none of them starts until the motion is decided.
Points to carry away
- The defendant, the government or the court may put competency in issue, and the court's duty is independent of any motion.
- The federal threshold is reasonable cause to believe the defendant may presently be incompetent.
- A court that fails to inquire despite evidence raising a bona fide doubt has denied due process.
- California requires the judge to state the doubt on the record and ask defense counsel for an opinion.
- All criminal proceedings are suspended once the question is properly raised.
- Delay from any proceeding to determine competency, including examinations, is excluded from the speedy trial computation.
Questions readers ask
Does raising competency waive anything?
Raising it does not waive the privilege against self-incrimination as to the offense, but it opens the defendant to a court-ordered examination, and what the defendant says in that examination is governed by its own rules. It also does not concede anything about the charge. What it does concede, in a practical sense, is time: the proceeding stops, the examination takes weeks, and any commitment for restoration takes months. That cost is real and should be weighed, though it is not a reason to leave a genuine question unraised.
Can the government raise competency over the defense's objection?
Yes. The federal statute names the attorney for the Government alongside the defendant as a party who may file the motion, and the court's own duty exists independently of both. Prosecutors sometimes move where a defendant intends to waive counsel or plead guilty and the record suggests the decision may not be rational. Defense objection is noted but does not control, because the constitutional prohibition on trying an incompetent defendant belongs to the process rather than to the party, and cannot be waived by the person whose capacity is in question.
What if counsel doubts competency but the client refuses an evaluation?
Counsel is not bound by the client's instruction on this point in most jurisdictions, because the question is whether the client can give instructions at all. Ethical guidance generally permits counsel to raise the issue where a reasonable belief exists that the client cannot participate, even against the client's wishes, while requiring counsel to avoid disclosing more confidential material than the inquiry needs. Some jurisdictions ask counsel to state a doubt without detailing its basis, and California's statute is structured that way.

More in Competency & Capacity
Statements Made During an Evaluation
Federal Rule of Criminal Procedure 12.2 bars use against the defendant of any statement made during a court-ordered mental examination, of expert testimony based on that statement, and of other fruits of it, except on an issue of mental condition the defense has itself raised. A competency finding is separately inadmissible at trial. A warning is constitutionally required before an examination whose results will be used at sentencing.
Commitment After an Insanity Acquittal
Federal law commits a person found not guilty only by reason of insanity to a suitable facility and requires a hearing within forty days. The acquittee bears the burden of showing that release would not create a substantial risk, by clear and convincing evidence where the offense involved bodily injury or serious property damage and by a preponderance otherwise. States cap the commitment differently and provide for extension on a dangerousness finding.
The Competency Evaluation and Who Conducts It
Federal law permits commitment for examination for a reasonable period not exceeding thirty days, extendable by fifteen, and requires the report to state the history and present symptoms, the tests used, the findings and the examiner's opinion on the statutory question. States differ on the number of examiners, their qualifications and where the examination occurs, and New York designates two with a third if they disagree.
