Relevance

General Principles

  • EC 350. Only relevant evidence is admissible.
  • EC 210. Relevant evidence is “Evidence…having any tendency in reason to prove or disprove any disputed fact that is of consequence to the determination of the action.”
  • Relevance vs. Weight
    • “Relevance” describes whether evidence should be heard because it might reasonably resolve a dispute. “Weight” describes the degree to which the jury finds the evidence probative. (People v. Turner (2020) 10 Cal.5th 786, 805.)
  • Probative Value. Test of relevance is whether the evidence tends logically, naturally, and by reasonable inference to establish material facts such as identity, intent, or motive. (People v. Garceau (1993) 6 Cal.4th 140, 177.)
    • The chief elements of probative value are relevance, materiality, and necessity. The court must ascertain that the evidence:
      • (1) tends logically, naturally, and by reasonable inference to prove the issue on which it is offered;
      • (2) is offered on an issue that will ultimately prove to be material to the party’s case; and
      • (3) is not merely cumulative with respect to other evidence that the party may use to prove the same issue. (People v. Schader (1969) 71 Cal.2d 761, 774-775.)

EC 352

  • EC 352. Trial court has discretion to exclude relevant evidence if its probative value is substantially outweighed by the probability that its admission will:
    • (a) necessitate undue consumption of time; or
    • (b) create substantial danger of undue prejudice, confusing the issues, or misleading the jury.
  • Prejudice. “Evidence is substantially more prejudicial than probative [only] if, broadly stated, it poses an intolerable ‘risk to the fairness of the proceedings or the reliability of the outcome.’” (People v. Waidla (2000) 22 Cal.4th 690, 724.)
  • “Evidence Code section 352 balancing is undertaken on a sliding scale. The more substantial the probative value of the evidence, the greater the danger of the presence of one of the excluding factors that must be present to support an exercise of trial court discretion excluding the evidence. Where the evidence relates to a critical issue, directly supports an inference relevant to that issue, and other evidence does not as directly support the same inference, the testimony must be received over a section 352 objection absent highly unusual circumstances.” (People v. Castaneda-Prado (2023) 94 Cal.App.5th 1260, 1285.)
  • Undue Prejudice. Undue prejudice is not evidence which will help convict a defendant; it is evidence that would allow a jury to convict the defendant for the wrong reason. The prejudice which exclusion of evidence under EC 352 is designed to avoid is not prejudice or damage to a defense that naturally flows from relevant, highly probative evidence. Rather, the statute uses the word in its etymological sense of “prejudging” a person or cause on the basis of extraneous factors. (People v. Escobar (1996) 48 Cal.App.4th 999, 1023.)
  • “Exclusion of evidence under Evidence Code section 352 is reserved for those cases where the proffered evidence has little evidentiary value and creates an emotional bias against the party.” (Hernandez v. County of Los Angeles (2014) 226 Cal.App.4th 1599, 1613.)
  • While the jury must be shielded from ” ‘depictions that sensationalize’ ” the alleged crimes, ” ‘the jury cannot be shielded from an accurate depiction of the charged crimes that does not necessarily play upon the emotions of the jurors.’ ” (People v. Streeter (2012) 54 Cal.4th 205, 238.)

EC 356

Miscellaneous Issues

Demonstrative Evidence

  • “Demonstrative evidence is evidence that is shown to the jury ‘as a tool to aid the jury in understanding the substantive evidence.’” (People v. Diaz (2014) 227 Cal.App.4th 362, 384, fn. 19.)
    • Common examples include maps, charts, and diagrams all of which illustrate a witness’s testimony. (Ibid.)
  • “[D]emonstrative evidence is admissible for the purpose of illustrating and clarifying a witness’ testimony’ so long as a proper foundation is laid.” (People v. Roldan (2005) 35 Cal.4th 646, 708.)
  • Demonstrative evidence, however, is not to be used as substantive evidence. (People v. Vasquez (2017) 14 Cal.App.5th 1019, 1036-1037.)
  • Computer Animations. Courts will “allow the admission of a computer animation as demonstrative evidence of expert testimony, but only if certain conditions are met. The animation must accurately depict an expert opinion, the expert opinion must fairly represent the evidence, the trial court must provide a proper limiting instruction, and the animation must otherwise be admissible under Evidence Code section 352. (People v. Caro (2019) 7 Cal.5th 463, 509.)

Consciousness of Guilt

Theft/Damage Valuation

  • People v. Romanowski (2017) 2 Cal.5th 903. To determine whether the value of stolen property exceeds the $950 threshold separating petty theft from grand theft, courts must apply a “reasonable and fair market value” test.
  • Reasonable and Fair Market Value test is the price a reasonable buyer and seller would agree on if the buyer wants to buy the property and the seller wanted to sell it, but neither was under an urgent need to buy or sell.
  • The owner of the stolen property may testify as to the value of that property, regardless whether the owner is an expert in the valuation of that particular property. (See People v. Henderson (1965) 238 Cal.App.2d 566, 567.) In addition, a juror may rely on his or her common knowledge regarding the value of consumer goods. (People v. Ortiz (2012) 208 Cal.App.4th 1354, 1366.)
  • Owner of personal property is qualified to opine about its value. (EC 813(a)(2).)
    • The owner of personal property who is familiar with its original cost and use is qualified to testify regarding its value…The owner of an article, whether he is generally familiar with such values or not, ought certainly to be allowed to estimate its worth. (People v. Haney (1932) 126 Cal.App. 473, 475.)
  • Trial court permitted to credit victim’s statement to infer that “stolen debit cards would have been valued in the marketplace at or near the balances in the linked accounts, that is, the highest price someone would have been willing to pay for cards to access those funds.” (Caretto v. Superior Court (2018) 28 Cal.App.5th 909, 921.)
  • Sales Tax is properly included in determination as to whether defendant stole item w/ a value greater than $950. (People v. Seals (2017) 14 Cal.App.5th 1210.)
  • Aggregating value of multiple thefts

Eyewitness Identification

  • In General. Admission of evidence in state trials is ordinarily governed by state law, and the reliability of relevant testimony typically falls within the province of the jury to determine.” (Perry v. New Hampshire (2012) 565 U.S. 228, 232.)
  • Due Process Right. To determine whether the admission of identification evidence violates a defendant’s due process rights, the court asks two questions
  • Exclusion of Evidence.
  • 402 Hearing. Not required where photo lineup “did not involve an unduly suggestive and unnecessary procedure. (People v. Wilson (2024) 16 Cal.5th 874, 904.)
  • Dispelling taint. The taint of an unduly suggestive lineup “map be dispelled if the People show by clear and convincing evidence that the identification of the defendant had an independent origin.” (People v. Ratliff (1986) 41 Cal.3d 675, 689.)
  • PC 859.7. Statute sets out ideal circumstances in which a photo lineup should be conducted (i.e. double blind)
    • But: “nothing in this section is intended to preclude the admissibility of any relevant evidence or to effect the standards governing the admissibility of evidence under the United States Constitution.” (PC 859.7(b).)

Immigration Status

  • Immigration status shall not be disclosed in open court unless judge first determines admissibility in an in camera hearing. (EC 351.4.)

Third Party Culpability

Self-Defense: Evidence of Prior Threats

  • Prior Threats from V to D. A defendant charged with assaultive crimes who claims self-defense may present evidence that the alleged victim had previously threatened him. (People v. Moore (1954) 43 Cal.2d 517, 527-529.)
  • Third-Party Threats to D. Evidence of third party threats is admissible to support a claim of self-defense if there is also evidence from which the jury may find that the defendant reasonably associated the victim with those threats. (People v. Minifie (1996) 13 Cal.4th 1055, 1060.)
