It may include testimony, documents, photographs, recordings, physical objects, stipulations, judicially noticed facts, summaries, expert opinions, business records, public records, and demonstrative aids. The judge decides most questions of admissibility. The jury decides disputed facts and weighs admitted evidence. The parties offer evidence, opponents object, and the judge rules. Rule 104(a) gives the judge authority to decide preliminary questions about admissibility, witness qualification, and privilege. In doing so, the judge is generally not bound by evidence rules except privilege rules. Rule 104(b) governs conditional relevance. When relevance depends on whether another fact exists, the judge admits the evidence if a reasonable jury could find the connecting fact. Relevance is a low threshold. Evidence is relevant if it has any tendency to make a consequential fact more or less probable. Relevant evidence is generally admissible unless another rule excludes it. Irrelevant evidence is inadmissible. Rule 403 permits exclusion when probative value is substantially outweighed by unfair prejudice, confusion, misleading the jury, delay, waste, or cumulative proof. The rule favors admissibility because the danger must substantially outweigh probative value. Some evidence is admissible for one purpose but not another. Limiting instructions help control the jury’s use of such evidence. Objections must usually be timely and specific to preserve error. If evidence is excluded, the proponent may need an offer of proof to show what the evidence would have established. Judicial notice allows courts to accept certain indisputable adjudicative facts without formal proof. In civil cases, the jury must accept judicially noticed facts as conclusive. In criminal cases, the jury may but need not accept them. Burdens of production and persuasion determine who must produce evidence and who must convince the factfinder. Presumptions may affect these burdens. The central lesson is that Evidence starts with purpose. Before applying any rule, ask: What is the evidence, who is offering it, and what fact is it offered to prove? That question is the foundation of relevance, admissibility, objections, and trial proof.
