Penal Code 1368 governs what happens when a doubt arises about a defendant's mental competence to stand trial. It is a protection that ensures no one is prosecuted who cannot understand the proceedings or assist in their own defense. I am Joel Brand, and here is how it works and when it matters in a DUI.
The text of the law
Penal Code 1368(a). If, during the pendency of an action and prior to judgment, or during revocation proceedings for a violation of probation, mandatory supervision, postrelease community supervision, or parole, a doubt arises in the mind of the judge as to the mental competence of the defendant, the judge shall state that doubt in the record and inquire of the attorney for the defendant whether, in the opinion of the attorney, the defendant is mentally competent. If the defendant is not represented by counsel, the court shall appoint counsel. At the request of the defendant or defendant's counsel or upon its own motion, the court shall recess the proceedings for as long as may be reasonably necessary to permit counsel to confer with the defendant and to form an opinion as to the mental competence of the defendant at that point in time.
What the statute provides
Section 1368 sets the process that begins when a judge develops a doubt about whether a defendant is mentally competent. The judge must state that doubt on the record, ask defense counsel for an opinion, appoint counsel if the defendant has none, and pause the proceedings so counsel can confer with the defendant. If the doubt is confirmed, the criminal case is suspended and competency proceedings follow. The underlying principle is constitutional: a person who cannot understand the proceedings or rationally assist in their defense cannot be tried.
The competency standard
Competence to stand trial has a specific meaning. A defendant is incompetent if, as a result of a mental disorder or developmental disability, they are unable to understand the nature of the criminal proceedings or to assist counsel in conducting a defense in a rational manner. It is a present-time question about the defendant's ability to participate, not a judgment about guilt and not the same as a mental-state defense to the charge. The focus is solely on whether the person can meaningfully take part in their own case right now.
When it can arise in a DUI
Competency questions are uncommon in routine DUI cases, but they do arise, particularly where a defendant has a serious mental illness, a cognitive impairment, a traumatic brain injury, or significant developmental disability. A DUI arrest can also intersect with an underlying psychiatric condition or a medical event that affected the driver. Where a client genuinely cannot understand the proceedings or help with the defense, raising competence is not a tactic but an ethical and constitutional necessity.
How competence is determined
Once a doubt is declared, the court typically appoints one or more qualified mental health experts to evaluate the defendant and report on competence. If the defendant is found competent, the criminal case resumes. If found incompetent, proceedings are suspended and the focus shifts to treatment aimed at restoring competence, after which the case may resume if competence is regained. The evaluations and the expert testimony are central, and the quality of that expert evidence matters greatly to the outcome.
Competence versus a mental-state defense
It is important not to confuse competence to stand trial with a defense based on the defendant's mental state at the time of the offense. They are entirely different. Competence is about the present ability to participate in the case; a mental-state defense concerns what the person understood or intended when the alleged offense occurred. A defendant can be fully competent to stand trial yet still have a mental-health issue relevant to the case in other ways, including through diversion. I keep these concepts distinct and pursue whichever genuinely applies.
The connection to mental health diversion
Where a mental health condition is part of the picture, the more common and often more constructive path in a DUI is mental health diversion under Penal Code 1001.36, which can lead to treatment and ultimately dismissal rather than punishment. Competence under 1368 and diversion under 1001.36 are different tools addressing different situations, and part of my job is recognizing which one fits a client's actual circumstances and pursuing it appropriately.
Protecting the client's rights
When competence is genuinely in question, raising it protects the client's most basic rights, and handling it sensitively, with the right experts and a clear understanding of the standard, is essential. It is never something to invoke lightly, but where it is real, it ensures the case proceeds only when the client can truly take part. I treat these situations with the care they require, balancing the client's dignity, their rights, and the realistic path through the case.
What suspension of the case means in practice
When a genuine doubt is declared and competence proceedings begin, the criminal case is paused, and that pause has practical effects a client needs to understand. The DUI charge does not go away; it waits. The separate DMV license process, however, runs on its own track and is not governed by the criminal court's competence finding, so the license side still has to be handled within its deadlines. Time spent in evaluation and any treatment to restore competence is not punishment, and it can sometimes inform a later, more constructive resolution of the case once the person is able to participate. I make sure clients and their families understand the sequence, what is paused, what continues, and what the realistic path forward looks like, so a frightening process is at least a clear one.
How it fits the larger defense
Competence under section 1368 is a procedural protection distinct from the merits defense, which centers on the lawfulness of the stop and the reliability of the chemical testing. Where mental health is relevant, it often connects to mental health diversion. See my top DUI defenses and the defenses guide.
