Mental Competency for Trial in California

Penal Code 1368 PC Explained

The Sixth Amendment to the United States Constitution guarantees all criminal defendants the right to a fair trial, including the right to understand the nature of the charges and to assist in their defense.

If a defendant is not mentally competent to understand the proceedings or to reasonably assist their attorney, conducting a criminal trial would violate those constitutional protections.

For this reason, California Penal Code 1368 (PC 1368) establishes a legal procedure that requires judges to suspend criminal proceedings whenever a defendant's mental competency is in doubt.

What Does Penal Code 1368 Say?

Penal Code 1368 provides that if, during the pendency of a criminal case and before judgment, a doubt arises in the judge's mind regarding the defendant's mental competency:

The judge must state that doubt on the record
The court must ask defense counsel for their opinion regarding competency
Criminal proceedings may be suspended pending further evaluation

In practical terms, a defendant cannot be tried or convicted unless they:

Understand the nature and purpose of the criminal proceedings, and
Can reasonably assist their criminal defense attorney

What Does “Incompetent to Stand Trial” Mean?

A defendant is considered mentally incompetent to stand trial if, due to a mental illness, developmental disability, or cognitive impairment, they are unable to meaningfully participate in their defense.

This determination focuses on the defendant's current mental condition, not their mental state at the time of the alleged offense.

Penal Code 1368 vs. Insanity Defense

Mental competency and legal insanity are separate legal concepts with different purposes and legal effects.

Mental competency (PC 1368) addresses whether the defendant can currently understand the proceedings and assist counsel. A finding of incompetency temporarily suspends the case.

Legal insanity focuses on whether the defendant was legally insane at the time the offense was committed. A successful insanity defense can result in a complete defense to criminal liability.

A defendant may be incompetent but not insane, or insane at the time of the offense but competent to stand trial.

Overview of the Penal Code 1368 Process

If a judge doubts a defendant's mental competency at any stage of the case, the following process applies:

The judge states the doubt on the court record
Defense counsel provides an opinion and supporting evidence
Criminal proceedings are suspended
The court orders a mental health evaluation
A competency hearing is conducted
The court determines competency by a preponderance of the evidence

If competency is restored, the criminal case resumes.

Legal Criteria for Mental Competency

Under California law, a defendant is mentally competent to stand trial if all of the following are true:

The defendant understands the nature and purpose of the criminal proceedings
The defendant can reasonably assist their attorney in presenting a defense
The defendant comprehends their role and status within the court process

When Does Mental Competency Become an Issue?

Mental competency most commonly arises in two situations:

1. Initial Court Appearance or Plea
A judge may question competency if the defendant appears confused, disoriented, delusional, or unable to communicate effectively with counsel.

2. Not Guilty by Reason of Insanity (NGRI) Plea
When a defendant enters an NGRI plea, the court orders a mental health evaluation. If the evaluation indicates incompetency, criminal proceedings are suspended.

What Is a Competency Hearing?

In Los Angeles County, competency cases are typically transferred to the Mental Health Courthouse.

Competency hearings are civil proceedings and differ from criminal trials. Key features include:

The hearing is conducted before a judge or jury
A jury determination must be requested
At least one court-appointed psychiatrist or psychologist evaluates the defendant
The defense bears the burden of proving incompetency

If the defendant is found competent, the case returns to the original criminal court.

What Happens If a Defendant Is Found Incompetent?

If the court finds the defendant mentally incompetent to stand trial:

Criminal proceedings are suspended
The defendant is committed to a state hospital or approved treatment facility
Mandatory psychiatric treatment is ordered
Commitment may last up to four months or longer
Proceedings resume only if competency is restored

Many defendants regain competency, even though underlying mental health conditions may continue to affect case strategy.

Why Early Legal Representation Matters

Without early legal intervention, mentally ill defendants often deteriorate in custody, where mental health treatment options are limited.

An experienced California criminal defense attorney can:

Raise competency issues at the earliest stage
Protect constitutional rights
Advocate for treatment-based outcomes
Prevent unlawful convictions
