Evidence Flashcards
(99 cards)
Logical relevance
All evidence must be logically relevant.
- FRE: Evidence is relevant if it has any tendency to prove or disprove a material fact.
- CEC: Evidence is relevant if it tends to be material to a disputed fact.
different language, same result.
Always analyze the relevancy of a piece of evidence first and state the FRE and CEC rules.
legal relevance
A balancing test is used to determine legal relevance:
- logically relevant evidence may be excluded if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of issues, misleading the jury, or wasting time.
CA Prop 8
Prop 8 is the “Victim’s Bill of Rights,” which provides that in criminal trials in CA state courts, all relevant evidence is admissible, even if objectionable under CEC, subject to a few special exemptions:
- Defendant still must open the door to bring in evidence of his own character before the prosecution can do so.
- Rape shield laws still limit evidence of a victim’s character.
- Member of media still can’t be held in contempt for refusing to reaveal a confidential news source.
- Court still has the power to exclude evidence using the legal relevance balancing test if the probative value is substantially outweighed by the danger of unfair prejudice, confusion of issues, misleading the jury, or wasting time. (CEC 352)
- Secondary evidence rule still applies.
- Hearsay may still not be admitted, unless subject to an exception.
- Exclusionary rules based on the US Constitution still applies.
- Exclusionary rules that were adopted by the California legislature with a 2/3 vote after 1982 still apply.
- Privileges that already existed in 1982 still apply (e.g. AC privilege, profession, and both marital privileges)
In a CA state court crim case, always state the first paragraph in the beginning.

types of objections to the form of the question (or answer)
- narrative: questions calling for a narrative are too broad.
- unresponsive: witness’s answer is unresponsive to the question. (CEC: a motion to strike can be made by either party, not just the examining party.)
- compound question: two questions are contained in one question.
- argumentative: the qeustion is unnecessarily combative.
- leading question on direct: the question is phrased to suggest the answer the questioner desires
- facts: assumes facts not in evidence.

present recollection refreshed
a technique that allows any item to be used to refresh a witness’s memory where the witness’s recollection is currently uncertain. Once shown the item, the witness must then testify from his refreshed memory.
- the item used to refresh is not considered evidence and may be otherwise inadmissible evidence.
- right to inspect: the adversary has a right to inspect the item, cross examine, and introduce pertinent portions into evidence.
- CEC: whether the refreshing is done before or during trial by means of a document, the writing must be produced or testimony is stricken unless the document is unavailable.
lay opinion testimony
admissible if rationally based on the witness’s perceptions and is helpful to the trier of fact. These are not legal conclusions, but opinions.
- FRE only: lay opinion may not be based on scientific or specialized knowledge.
expert opinion
admissible if all of the following are satisfied:
- specialized knowledge will assist the trier of fact in understanding the evidence or determining a fact.
- the witness is qualified as an expert by knowledge, skill, experience, training, or education.
- the testimony is based on sufficient facts or data. The expert’s opinion may be based on: 1) firsthand knowledge; 2) observation of prior witnesses; or 3) a hypothetical question posed by counsel.
- the testimony is the product of reliable principles and methods. FRE applies Daubert standard; CEC applies Kelly/Frye standard.
- the witness has applied the principles reliably to the facts of the case.
FRE: Daubert standard
FRE: Daubert standard of reliability requires the substance of the expert’s testimony to be:
- peer-reviewed and published in scientific journals
- tested and subject to retesting,
- known for a low error rate, and
- subject to a reasonable level of acceptance.
CEC: the Kelly/Frye standard
Kelly/Frye standard of reliability requires:
- the proponent must prove that the underlying scientific theory and the intstrument it uses—
- has been generally accepted as valid and reliable in the relevant scientific field.
CEC exception: the standard does not apply to medical and nonscientfic testimony.
impeachment
a witness’s credibility may be impeached by cross-examination, or with the proper foundation, by extrinsic evidence. Either party may impeach a witness.
five ways to impeach a witness
- character for truthfulness
- prior inconsistent statement
- bias
- sensory or mental defect
- contradiction of a witness’s testimony by another witness
