How a Jury Trial in California Criminal Cases Works

Under the California Constitution, anyone charged with a misdemeanor or felony has the right to a jury trial.

A jury trial is the cornerstone of the criminal justice system and represents the strongest safeguard against wrongful conviction.

A jury consists of 12 members of the community, plus alternates, who serve as the finders of fact. Their job is to determine whether the prosecution has proven each element of the charged crimes beyond a reasonable doubt.

While many criminal cases are resolved through dismissal or plea negotiations, cases that proceed to trial are almost always decided by a jury rather than a judge.

If you've been charged with a crime in Los Angeles, one of the first and most important questions is how long the process will take. The answer depends on several factors.

A Penal Code 1050 motion to continue is a formal request to postpone a scheduled court date in a criminal case.

Jury Trial vs. Bench Trial

A defendant may waive the right to a jury trial and instead choose a bench trial, where the judge acts as the finder of fact. This option is available only if both sides agree.

A bench trial may be strategically advantageous in limited circumstances, such as:

Highly technical legal issues
Emotionally charged allegations
Cases turning on narrow legal interpretations

However, most criminal trials in California are jury trials, particularly in felony cases.

Right to a Fair and Representative Jury

One of the most important protections in a criminal jury trial is the requirement that the jury represent a fair cross-section of the community.

While no jury will perfectly mirror community demographics, the law strictly prohibits:

Excluding jurors based on race or ethnicity
Striking jurors based on gender, sexual orientation, or national origin
Using stereotypes to influence jury selection

This ensures that defendants are judged by a jury of their peers, not a hand-picked panel designed to favor one side.

The Defendant's Right to an Attorney

At trial, the accused has the constitutional right to:

Be represented by an attorney, or
Represent themselves if they knowingly and intelligently waive counsel

If a defendant cannot afford a lawyer, the court must appoint one.

Effective legal representation is not optional—it is constitutionally required. A failure to provide competent representation may result in the reversal of a conviction.

A Penal Code 995 motion to dismiss is a highly effective tool in California criminal defense. It enables a defendant to contest the legality of the charges following a preliminary hearing and request the court to dismiss some or all of them.

Stages of a California Criminal Jury Trial

A jury trial follows a structured process designed to protect the defendant's rights at every stage.

Jury Selection (Voir Dire)

The trial begins with jury selection, during which potential jurors are questioned by the court and attorneys to determine whether they exhibit bias or are unable to be impartial.

Attorneys may remove jurors:

For cause (e.g., bias, conflict of interest), or
Through a limited number of peremptory challenges

Improper juror exclusion can result in reversible error.

Opening Statements

Opening statements provide the jury with a roadmap of the case.

The prosecutor goes first
The defense follows

Opening statements are not evidence. They outline what each side expects the evidence to show.

Presentation of Evidence

Evidence may include:

Live witness testimony
Physical evidence
Photographs or videos
Audio recordings
Documents

The prosecution presents its case first. The defense may then present evidence, but is never required to do so.

Cross-Examination and Confrontation

The defendant has the constitutional right to confront and cross-examine witnesses.

Cross-examination allows defense counsel to:

Expose inconsistencies
Challenge credibility
Reveal bias or motive
Undermine unreliable testimony

With limited exceptions, the prosecution cannot rely on testimony that cannot be cross-examined.

Expert Witness Testimony

Both sides may present expert witnesses to explain:

Scientific evidence
Medical findings
Forensic analysis
Technical data

Many criminal trials become a battle of experts, where credibility and methodology are decisive.

Closing Arguments

After all evidence is presented:

The prosecution delivers its closing argument
The defense responds
The prosecution may give a brief rebuttal

Attorneys summarize evidence and argue how the jury should interpret it. No new evidence may be introduced.

Jury Instructions and Deliberations

The judge reads formal jury instructions, explaining:

The elements of each crime
The burden of proof
Legal definitions jurors must apply

The jury then deliberates in private, selecting a foreperson to guide the discussion.

Jurors must reach a unanimous verdict to convict.

Jury Verdicts in California Criminal Cases

A criminal conviction requires a unanimous guilty verdict.

If the jury cannot reach unanimity:

The court may declare a hung jury
The prosecution may retry the case with a new jury

If the jury finds the defendant not guilty, the case is dismissed and cannot be retried.

Presumption of Innocence and Burden of Proof

Every defendant who enters a trial is presumed innocent.

The prosecution must prove guilt beyond a reasonable doubt, the highest legal standard in the justice system. The defense bears no burden to prove innocence.

Sentencing After a Jury Trial

If a defendant is convicted, the case proceeds to a sentencing hearing.

At sentencing:

The defense presents mitigating factors
The prosecution presents aggravating factors
The judge determines the lawful sentence

Sentencing outcomes can vary widely depending on advocacy and strategy.

Why Jury Trials Matter

Jury trials protect against:

Government overreach
Biased enforcement
Unreliable accusations

They ensure accountability and fairness through public participation.
