Evidence Flashcards
California Introductory Paragraph
Under Proposition 8 of the California Constitution (hereafter Prop. 8), any evidence that is relevant may be admitted in a criminal case. However, Prop. 8 makes an exception for balancing under California Evidence Code (hereafter CEC) 352, which gives a court discretion in excluding relevant evidence if its probative value is substantially outweighed by a risk of unfair prejudice, confusion of issues, or misleading the jury.
(If it’s a civil case, note Prop. 8 does not apply.)

Judicial Notice
The court’s acceptance of a fact as true without requiring formal proof. Facts are subject to judicial notice if:
i) The fact is generally known within the territorial JX of the court; or
ii) The fact can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.

Direct examination: not allowed, unless necessary to develop testimony (preliminary info), witnesses with difficulty communicating, antagonistic witnesses
Cross examination: allowed for questions within scope
Types of improper questions
CACAR!
Compound questions
Assumpes facts not in evidence
Calls for conclusion / opinion
Argumentative
Repetitive
Burden of production
A party’s obligation to provide sufficient evidence to support proposition of fact.
Burden of persuasion
A party’s obligation to convince the factfinder to believe a proposition.
Civil standard: preponderance (clear and convincing for fraud)
criminal: beyond a reasonable doubt
Rebuttable presumption
Shifts the burden of production (but not persuasion) to the opposing party.
Bursting bubble theory (FRE): a presumption “bursts” after sufficient evidence is introduced to sustain a contrary finding, so it is no longer preclusive.
No burst: judge instructs jury to accept presumption.
Burst: judge may instruct jury they may (but are not required to) draw conclusion.
Conclusive presumption
Treated as rules of substantive law and may not be challenged by contrary evidence, no matter how strong the proof.
Destruction of Evidence Presumption
raises a rebuttable presumption that such evidence would have been unfavorable to the party who destroyed the evidence. Proponent must establish:
1) Destruction was intentional
2) Destroyed evidence was relevant
3) Proponent acted with due diligence
Relevance of Evidence
Evidence must be relevant to be admissible. It must be both logically and legally relevant.
Logical: Evidence is logically relevant if it is PROBATIVE and MATERIAL.
Legal: Relevant evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice.
Character evidence
Character evidence is evidence offered to show a person’s general personality traits or propensities. As a general rule, character evidence is generally inadmissible.

- prosecution cross-examine D’s character witness with reputation, opinion, or ask about specific bad acts
Bad character evidence about victim

Habit evidence
Habit evidence is evidence of a person’s habit or an organization’s routine. It is admissible to prove that the person or organization acted in accordance with a habit or routine on a particular occasion.

Any person with personal knowledge who gives an oath to testify truthfully is competent to be a witness. A person who is unable to understand the requirement to tell the truth is incompetent.
Lay opinions

- rationally based on witness’s perception
- helpful to understanding their testimony or making a factual determination
- not based on scientific, technical, specialized knowledge
Expert opinions

i) based on sufficient facts/data
ii) a product of reliable principles and methods
iii) reflection of reliable application of principles
It can be based on inadmissible materials if experts in the field would reasonably rely.
CA DISTINCTION: Requires preliminary showing that new scientific theory or technique has been generally accepted as valid in the field; trial court as gatekeeper.
Impeachment
Impeachment attacks the credibility of a testifying witness based on character for untruthfulness, bias, perception, or prior contradictory statements. Any party may attack the credibility of any witness.
Reputation and opinion evidence (impeachment)
A witness may testify about the opinion or reputation for another witness’s truthfulness.
Specific instances (impeachment)
