Parties

• California Court of Appeal, Third Appellate District (party)

Scenario: You are on trial for assault, and the prosecution wants to introduce evidence that you were involved in a similar fight five years ago, even though you weren't convicted.

Your Rights: You have the right to argue that this evidence is only being used to make you look bad (propensity) and doesn't prove you committed the current crime. You can argue its potential to unfairly prejudice the jury outweighs its relevance to motive or identity.

What To Do: Ensure your attorney objects to the introduction of prior uncharged misconduct if it appears to be solely for propensity. Argue for its exclusion based on undue prejudice and lack of relevance to specific issues like motive or identity.

Scenario: You are on trial and believe you acted in self-defense, but you are concerned the judge's instructions to the jury about self-defense were confusing.

Your Rights: You have the right to have the jury properly instructed on the law, including self-defense. If the instructions are legally incorrect or confusing, your conviction could be overturned.

What To Do: Your attorney should carefully review the jury instructions for accuracy and clarity. If there are issues, they should object and propose alternative instructions to ensure the jury understands the law of self-defense.

Is it legal to use evidence of someone's past bad behavior in their current trial?

Depends. Evidence of prior uncharged misconduct is generally inadmissible if used solely to show a person's bad character or propensity to commit crimes. However, it can be admissible if it is relevant to proving specific issues like motive, identity, or intent, and its probative value is not substantially outweighed by the risk of unfair prejudice.

This applies in California courts, based on Evidence Code § 1101(b).

For Criminal Defendants

Defendants face the possibility that evidence of past uncharged misconduct could be admitted against them, potentially influencing the jury's perception, even if it doesn't directly prove guilt of the current charge. This makes it crucial for defense attorneys to vigorously challenge the admissibility of such evidence.

For Prosecutors

Prosecutors may have a stronger basis to introduce evidence of prior uncharged misconduct if they can clearly demonstrate its relevance to motive or identity, rather than just character. This can be a powerful tool in building a case, but requires careful justification to avoid reversal on appeal.

For Jurors

Jurors may hear evidence about a defendant's past actions that are not part of the current charges. They must be instructed and understand that this evidence can only be considered for specific purposes (like motive or identity) and not as proof of general bad character.
