Key Legal Definitions

Rule Statements

Evidence of prior uncharged misconduct is admissible under Evidence Code section 1101(b) when it is relevant to prove identity or intent, and its probative value is not substantially outweighed by the risk of undue prejudice.

Jury instructions on self-defense, when read as a whole, are adequate if they accurately and completely convey the applicable legal principles to the jury.

A claim of ineffective assistance of counsel requires a showing of both deficient performance and resulting prejudice to the defense.

Remedies

Conviction affirmed.

Scenario: You are on trial for a crime, and the prosecution wants to introduce evidence of unrelated bad things you did in the past.

Your Rights: You have the right to argue that this past conduct is not relevant to the current charges or that it is unfairly prejudicial, meaning it's more likely to make the jury dislike you than prove you committed the crime.

What To Do: Your attorney should object to the introduction of such evidence, arguing it violates Evidence Code sections 1101(b) and 352. They should highlight why the prior acts are not similar enough to prove identity or intent, or why the potential for prejudice is too high.

Scenario: You are facing criminal charges and believe the jury instructions on self-defense given by the judge were incorrect or incomplete.

Your Rights: You have the right to have the jury instructed accurately on the law, including all elements of self-defense.

What To Do: Your attorney must have objected to the instructions at trial and, if convicted, must argue on appeal that the instructions, when read as a whole, misstated the law or failed to cover essential elements, potentially leading to a wrongful conviction.

Is it legal to use evidence of someone's past crimes to prove they committed a new crime?

Depends. Under California Evidence Code § 1101(b), evidence of past uncharged misconduct can be legally admissible to prove specific issues like identity, intent, motive, or plan, but only if its probative value is not substantially outweighed by the risk of unfair prejudice.

This applies in California state courts.

For Criminal defendants

Defendants may face convictions based on evidence of prior uncharged misconduct if it is deemed relevant to prove identity or intent and its prejudicial effect is outweighed by its probative value. This makes it harder to exclude such evidence.

For Prosecutors

Prosecutors have a clearer path to introduce evidence of prior uncharged misconduct to establish identity and intent, provided they can demonstrate its relevance and argue that its probative value outweighs potential prejudice.

For Defense attorneys

Defense attorneys must be prepared to vigorously challenge the admissibility of prior uncharged misconduct evidence, focusing on arguments of irrelevance to identity/intent or substantial prejudice under Evidence Code § 352.
