Parties

• California Court of Appeal for the Third Appellate District (party)

Scenario: You are on trial for assault, and the prosecution wants to introduce evidence of a fight you had last year that didn't lead to charges.

Your Rights: You have the right to object to the introduction of this evidence if it's only being used to show you have a bad character or are likely to commit crimes. However, if the prosecution can show it's relevant to proving motive, identity, or intent in the current case, and its value outweighs the prejudice, it might be admitted.

What To Do: Ensure your attorney understands the rules of evidence regarding prior bad acts and objects to inadmissible evidence. If admitted, request limiting instructions to the jury on how they can and cannot use the evidence.

Scenario: You are claiming self-defense in a criminal case, but the jury convicts you anyway.

Your Rights: You have the right to have the jury instructed on self-defense if there is any evidence, however slight, that supports your claim. If the instructions are flawed or the evidence overwhelmingly supports your claim and the jury's rejection is unreasonable, you may have grounds for appeal.

What To Do: Work with your attorney to ensure self-defense is properly raised and that jury instructions accurately reflect the law. If convicted, discuss with your attorney whether the jury instructions or the verdict itself warrants an appeal.

Is it legal to use evidence of someone's past bad behavior in court?

It depends. Generally, evidence of past bad behavior that didn't result in a conviction (uncharged misconduct) cannot be used to show someone is a bad person or likely to commit a crime. However, it can be admitted if it's relevant to proving specific issues like motive, identity, intent, or a common plan, and its usefulness isn't outweighed by the risk of unfair prejudice.

This applies in California, as per People v. Jackson.

Can I get a jury instruction on self-defense if I claim I acted in self-defense?

Yes, if there is any evidence, no matter how weak, that supports your claim of self-defense. The judge must provide instructions to the jury explaining the law of self-defense. However, the jury ultimately decides if the evidence supports your claim.

This is the standard in California, as affirmed in People v. Jackson.

For Criminal defendants facing charges

Defendants should be aware that evidence of past uncharged misconduct might be admissible against them if it's relevant to proving motive or identity, even if it didn't lead to a conviction. This could make it harder to defend against charges.

For Prosecutors

Prosecutors have a clearer path to introduce evidence of prior uncharged misconduct if they can demonstrate its relevance to motive or identity and argue that its probative value outweighs potential prejudice. This can strengthen their case.

For Attorneys

Attorneys must be diligent in both seeking to admit relevant prior misconduct evidence for their case and objecting to its admission when it's offered unfairly against their client. They also need to ensure self-defense instructions are accurate and supported by the evidence.
