1.4 Classification of Evidence: Relevancy, Physical Structure, Probative Value

1. By relevancy: relevant (the admissible candidates) vs irrelevant (the excluded); the direct (proving the fact itself) vs the circumstantial (proving by inference — the chain's logic). 2. By physical structure: oral (the testimony — the witness's words), documentary (the documents — the writings-and-records), real/material (the objects — the knife, the stains); the digital (the newest — U4.3). 3. By probative value: prima facie (the rebuttable proof), conclusive (the irrebuttable), the corroborative (the supporting), the hearsay (the secondhand — U2.3). 4. By the source: the prosecution's-and-defence's; the judicial-and-party's; the expert's (the opinion's exception). 5. By the effect: the substantive (the fact's proof) vs the credibility (the witness's testing).
