- remote convictions: exclude if probative value substantially outweighs prejudicial effect + give party written notice
judge vs. jury roles on preliminary questions
jury decides on RELEVANCE: authenticity, agent status, personal knowledge (judge just decides if a jury COULD find)
judge decides on ADMISSIBILITY: competency of witnesses, privileges, hearsay exceptions
judicial notice
conclusive on the jury in a civil case
not conclusive in a criminal case (just satisfies burden of production)
when is an expert witness appropriate
- where specialized knowledge would be helpful
- based on sufficient facts/data
- witness is qualified
- has a proper factual basis
where is a lay witness appropriate
- rationally based on the perception of the witness
- helpful to a clear understanding of testimony/determination of a fact
- not based on scientific, technical, specialized knowledge
where impeachment is allowed by extrinsic evidence
- prior inconsistent statement
- bias
- sensory deficiency
- contradiction (unless impeaching fact is collateral)
- prior convictions
where impeachment is allowed by reputation/opinion evidence only
- opinion/reputation for untruthfulness

testimonial vs. non testimonial
testimonial = primary purpose of interrogation is to establish or prove past events potentially relevant to a later criminal prosecution
non testimonial = primary purpose is to help police address an ongoing emergency
