Being convicted of a crime in California does not necessarily mean the case is over. Under California law, a defendant may have the right to appeal a criminal conviction, sentence, or certain other appealable orders when there are legal grounds for challenging what happened in the trial court. However, an appeal is not simply another opportunity to present the same case to a different judge or jury. Instead, an appellate court generally reviews the existing record to determine whether the trial court made a significant legal or procedural error that affected the outcome.

The rules governing criminal appeals can be complicated, and strict filing deadlines apply. In California, the deadline is generally 60 days for a felony appeal and 30 days for a misdemeanor appeal. The requirements can also change depending on whether the conviction followed a trial, guilty plea, or no-contest plea. Understanding whether an appeal is available, what issues can be raised, and what must be filed is important for anyone considering challenging a California criminal conviction.

Key Takeaways

• Yes, a criminal conviction can be appealed in California, but the defendant generally must identify a legal error or another recognized basis for appellate review.

• An appeal is not a new trial. The appellate court generally reviews the existing trial-court record rather than hearing new witnesses or considering new evidence.

• Felony and misdemeanor appeals have different deadlines. A defendant generally has 60 days to appeal a felony judgment and 30 days to appeal a misdemeanor judgment.

• Appealing after a guilty or no-contest plea can be more complicated. In many felony cases, a defendant challenging the validity of the plea must obtain a certificate of probable cause after following the procedures in Penal Code section 1237.5.

• Possible grounds for appeal can include legal errors, improper admission or exclusion of evidence, incorrect jury instructions, and insufficient evidence.

• The appellate court does not simply decide which side it believes. It reviews the record under applicable legal standards and generally does not reassess witness credibility in the way a trial court does.

• Missing the deadline can be extremely serious. California Rules of Court generally do not permit a court to extend the deadline for filing a criminal notice of appeal.

Can You Appeal A Criminal Conviction In California?

Yes. A defendant convicted of a crime in California may have the right to appeal the judgment or certain appealable orders. California courts explain that a person found guilty at trial has a right to appeal, although the appeal is limited in scope and does not function as a second trial.

The purpose of a criminal appeal is generally to determine whether the trial court committed an error that affected the defendant's legal rights or the outcome of the case. The appellate court examines the record from the lower court, including relevant transcripts, exhibits, motions, rulings, jury instructions, and other materials that were properly made part of the record.

What Does A Criminal Appeal Challenge?

Depending on the circumstances, an appeal may challenge issues such as:

• The admission of evidence that should have been excluded.

• The exclusion of evidence that should have been admitted.

• Incorrect or incomplete jury instructions.

• Improper legal rulings by the trial judge.

• Constitutional violations.

• Prosecutorial misconduct that resulted in prejudicial error.

• Insufficient evidence to support the conviction.

• Errors involving sentencing.

• Other legal or procedural errors that affected the defendant's substantial rights.

Not every mistake made during a criminal proceeding automatically results in reversal. Generally, the defendant must establish an appealable error and demonstrate why the error was significant enough to warrant relief.

California courts explain that an appeal generally requires showing that the trial court made a legal mistake and that the mistake affected the outcome.

How Is A Criminal Appeal Different From A New Trial?

One of the most important things to understand about appealing a California criminal conviction is that an appeal is not a new trial.

At trial, the judge or jury evaluates testimony, physical evidence, documents, and other evidence presented by the parties. An appellate court generally does not conduct that process again. Instead, appellate judges review the existing record to determine whether the trial court made a legal error.

Can You Introduce New Evidence On Appeal?

Generally, no.

A defendant cannot ordinarily use a criminal appeal to introduce a new witness, submit evidence that was never presented to the trial court, or tell the appellate court about facts that are outside the existing record. California Courts specifically explain that new evidence and new witnesses generally cannot be introduced during an appeal.

This makes the trial record extremely important. If an attorney intends to challenge a ruling made during the trial, the relevant proceedings, objections, motions, exhibits, and transcripts may become critical to the appellate court's review.

Can The Appellate Court Reweigh Witness Credibility?

Generally, an appellate court does not reweigh the credibility of witnesses simply because the defendant disagrees with the trial court's assessment.

For example, arguing that a jury should have believed one witness instead of another generally is not enough by itself to establish an appellate error. Appellate courts review the record under established standards of review rather than conducting their own credibility assessment.

What Are The Grounds For Appealing A Criminal Conviction?

There must generally be a legally recognized basis for an appeal. A defendant cannot appeal simply because they are unhappy with the verdict or believe the punishment is unfair.

The specific grounds depend on the facts and procedural history of the case.

Errors In Applying The Law

A trial court may make an appealable error by applying the wrong legal standard, misinterpreting a statute, or incorrectly applying constitutional or case law.

For example, an appeal might challenge whether the trial court properly applied the law governing a particular evidentiary issue or constitutional protection.

Improper Admission Or Exclusion Of Evidence

Evidence can play a central role in a criminal case. If a trial judge improperly admits damaging evidence or excludes evidence that should have been presented to the jury, the error may potentially provide grounds for an appeal.

However, the existence of an error does not necessarily mean the conviction will automatically be overturned. The appellate court may consider whether the error was prejudicial under the applicable legal standard.

Incorrect Jury Instructions

Jurors must be instructed on the law applicable to the charges and defenses presented at trial. If the jury receives an incorrect or inadequate instruction and the error affects the defendant's rights, the issue may potentially be raised on appeal.

The precise significance of an instructional error depends on the circumstances of the case and the applicable law.

Insufficient Evidence

A defendant may also challenge whether the evidence was legally sufficient to support a conviction.

This is different from arguing that the jury should have believed a different witness. The appellate question generally concerns whether the evidence in the record was legally sufficient to support the verdict under the applicable standard of review. California courts identify insufficient evidence and legal errors as examples of issues that may be raised in a criminal appeal.

Constitutional Or Procedural Errors

Constitutional issues can sometimes form the basis of a criminal appeal. Depending on the facts, these may involve alleged violations of constitutional rights during the investigation, trial, or sentencing process.

Procedural errors may also be relevant when they substantially affected the fairness or outcome of the proceedings.

What Is The Deadline To Appeal A Criminal Conviction In California?

The deadline depends on the type of criminal case.

Felony Appeals

For a felony case, California Rules of Court, rule 8.308 generally requires the notice of appeal to be filed within 60 days after the rendition of the judgment or the making of the appealable order.

California Courts' self-help materials likewise state that defendants generally have 60 days to file a felony notice of appeal. Felony appeals are handled by the California Court of Appeal.

Misdemeanor Appeals

Misdemeanor appeals generally have a shorter deadline. California courts state that a defendant generally must file a misdemeanor Notice of Appeal within 30 days of the judgment or order. Misdemeanor appeals are generally handled by the appellate division of the superior court.

Why The Deadline Matters

The deadline for filing a notice of appeal should not be treated as a flexible guideline. Rule 8.308 provides that, subject to specified exceptions, the court cannot extend the time to file a criminal notice of appeal. A late notice can be marked as received but not filed.

Because the applicable deadline can depend on the type of case and the judgment or order being challenged, a defendant considering an appeal should address the issue promptly.

How Do You Start A Criminal Appeal In California?

The first major step is generally filing a notice of appeal in the appropriate trial court.

For felony cases, California Rule of Court 8.304 provides that an appeal from a judgment or appealable order is initiated by filing the notice of appeal in the superior court. The notice must identify the judgment or order being appealed.

The notice of appeal is important, but it is only the beginning of the appellate process.

The Record On Appeal

After the notice is filed, the record from the trial court must be prepared for appellate review. In felony criminal appeals, the normal record generally includes a clerk's transcript and reporter's transcript.

The record can include important materials such as:

• The charging documents.

• Motions and written pleadings.

• Court minutes.

• Jury instructions.

• Verdicts.

• The judgment.

• Relevant exhibits.

• Transcripts of oral proceedings.

• Motions for a new trial.

• Other documents relevant to the issues being raised.

The appellate court generally cannot consider matters that were never made part of the trial-court record.

Appellate Briefs

The appellant's opening brief is a central part of the appeal. It explains the alleged legal errors, supports the arguments with applicable authorities, cites the record, and explains the relief being requested.

California courts describe the opening brief as one of the most important parts of an appeal because the appellate court decides the case based on the briefs, the appellate record, and applicable legal research rather than conducting a new trial.

What Happens After You Appeal A California Criminal Conviction?

Once an appeal is properly initiated, the process can involve several stages.

Record Preparation And Review

The record from the trial court is assembled and transmitted according to the applicable appellate rules. The appellant's attorney reviews the record for potential legal errors and develops the arguments that can properly be presented to the appellate court.

This review can be extensive. A criminal trial may contain hundreds or thousands of pages of documents and transcripts, depending on the complexity of the case.

Briefing

The appellant generally files an opening brief explaining why the judgment should be reversed, modified, or otherwise changed.

The opposing side then has an opportunity to respond. The appellant may have an opportunity to file a reply brief addressing arguments raised in the response.

The briefing stage is particularly important because the appellate court's review is focused on the legal arguments presented within the applicable procedural rules.

Oral Argument

In some cases, the parties may participate in oral argument. Oral argument gives the appellate judges an opportunity to ask questions and allows the attorneys to emphasize important legal points.

However, oral argument does not transform the appeal into a new trial. The appellate court remains focused on the record and legal issues properly before it.

The Appellate Decision

After reviewing the record and arguments, the appellate court may issue a decision.

Depending on the circumstances, the court may affirm the judgment, reverse it in whole or in part, modify the judgment, or send the matter back to the trial court for further proceedings. California appellate courts explain that appellate review focuses on whether the lower court properly applied the law and followed the required procedures.

An appellate victory therefore does not always mean that the defendant is immediately released or that every aspect of the case disappears. The precise result depends on what error the court finds and what remedy is legally appropriate.

Can You Appeal After Pleading Guilty Or No Contest?

Appealing after a guilty or no-contest plea is different from appealing a conviction following a trial.

California Penal Code section 1237.5 generally provides that a defendant cannot appeal from a judgment of conviction following a guilty or nolo contendere plea, or from a probation revocation following an admission of violation, unless specified requirements are satisfied. Among other things, the defendant must file a written statement addressing reasonable constitutional, jurisdictional, or other grounds going to the legality of the proceedings, and the trial court must issue a certificate of probable cause.

California Rule of Court 8.304 similarly addresses appeals following guilty or no-contest pleas and explains when a certificate of probable cause is required.

Are All Issues After A Guilty Plea Barred?

Not necessarily.

The requirements for an appeal after a guilty or no-contest plea depend on what the defendant is challenging. Some issues may not require a certificate of probable cause, while challenges concerning the validity of the plea generally implicate the requirements of Penal Code section 1237.5.

Because the distinction can be technical and the deadlines remain important, someone who entered a guilty or no-contest plea should have the specific appellate issue evaluated promptly.

What Can Happen If You Win A Criminal Appeal?

Winning an appeal does not necessarily produce the same result in every case.

The appropriate remedy depends on the legal error identified by the appellate court. Possible outcomes can include:

• Reversal of the conviction.

• Modification of the judgment or sentence.

• A new proceeding in the trial court.

• Remand to the trial court for further action.

• Other relief specifically ordered by the appellate court.

In some circumstances, the appellate court may conclude that an error occurred but that the error did not justify reversing the conviction. This is why identifying a legal error is only part of an effective appellate strategy. The defendant may also need to establish that the error was prejudicial under the applicable standard.

What If The Court Of Appeal Rejects The Appeal?

An unsuccessful appeal is not necessarily the end of every possible legal challenge, although the available options become more limited and depend heavily on the circumstances.

After a California Court of Appeal decision, a party may potentially seek rehearing or review by the California Supreme Court when the applicable requirements are met. California courts explain that parties have options after an appellate decision, including seeking rehearing or review by a higher court.

Other post-conviction remedies may also exist in particular circumstances. These are separate from a standard direct appeal and have their own eligibility requirements, procedures, and deadlines.

Why You Should Review A Potential Appeal Quickly

A criminal appeal can depend on issues that occurred months or even years earlier during the investigation, pretrial proceedings, trial, or sentencing. Important questions may include whether objections were properly made, whether evidence was admitted correctly, whether jury instructions were legally adequate, and whether the record preserves the issue for appellate review.

The strict filing deadlines make timing especially important. For felony cases, California generally provides 60 days for filing the notice of appeal, while misdemeanor appeals generally have a 30-day deadline.

An attorney reviewing a potential appeal may need to examine the judgment, sentencing documents, transcripts, motions, exhibits, jury instructions, and other portions of the record before determining whether there is a viable appellate issue.

Conclusion

So, can you appeal a criminal conviction in California? Yes, in many circumstances, but an appeal requires more than simply disagreeing with the verdict. A criminal appeal generally asks a higher court to determine whether the trial court committed a legal or procedural error that affected the defendant's case. The appellate court generally reviews the existing record rather than conducting a new trial or hearing new evidence.

The process also has strict deadlines and different rules for felony and misdemeanor cases. Appeals following guilty or no-contest pleas can involve additional requirements, including a certificate of probable cause for certain challenges. Because an untimely notice of appeal can prevent appellate review, anyone considering an appeal should act quickly.

Frequently Asked Questions About Criminal Appeals In California

1. Can I Appeal A Criminal Conviction If I Believe The Jury Made The Wrong Decision?

Potentially, but simply disagreeing with the jury's assessment of the evidence is generally not enough. An appeal focuses on legal errors and the record from the trial court rather than providing an opportunity to retry the factual dispute.

2. How Long Do I Have To Appeal A Felony Conviction In California?

Generally, a defendant has 60 days to file a notice of appeal from a felony judgment or appealable order, subject to the applicable rules and circumstances. California Rule of Court 8.308 governs the general timing requirement for criminal appeals.

3. How Long Do I Have To Appeal A Misdemeanor Conviction In California?

Generally, a misdemeanor defendant has 30 days from the judgment or appealable order to file a notice of appeal. Misdemeanor appeals are generally handled by the superior court's appellate division.

4. Can I Appeal After Pleading Guilty?

Possibly, but the rules are more restrictive. For certain challenges to a conviction following a guilty or no-contest plea, California Penal Code section 1237.5 requires a written statement and certificate of probable cause.

5. Can I Present New Evidence During A Criminal Appeal?

Generally, no. An appeal is based on the existing record from the trial court. New witnesses and new evidence ordinarily cannot be introduced simply because the defendant is appealing the conviction.

6. Does Filing An Appeal Automatically Overturn My Conviction?

No. Filing a notice of appeal starts the appellate process but does not itself establish that the conviction was legally incorrect. The appellate court reviews the issues raised and the record before determining whether relief is warranted.

7. What Happens If I Miss The Deadline To Appeal?

Missing the applicable deadline can be fatal to an appeal. California's criminal appellate rules generally do not allow the court to extend the deadline for filing a notice of appeal, subject to limited exceptions recognized by law.

8. Do I Need An Attorney To Appeal A Criminal Conviction?

A defendant may have certain rights to appointed counsel depending on the circumstances, and California courts recommend consulting an attorney familiar with appeals. Criminal appeals involve specialized procedural rules, deadlines, legal research, record citations, and briefing requirements.

9. Is An Appeal The Same As Asking For A New Trial?

No. An appeal generally asks an appellate court to review the trial court's decision for legal error. It is not a second trial where the parties present new evidence and witnesses.

10. What Should I Do If I Am Considering Appealing A California Conviction?

You should address the potential appeal as soon as possible, particularly because the filing deadline may be as short as 30 days in a misdemeanor case. Gather your judgment, sentencing documents, court filings, and other case records and speak with a qualified California criminal defense attorney about the available appellate options.
