1. Any object or information, other than legal submissions, which tends to prove or disprove the existence of a fact in issue. There are three primary forms of evidence, testimony, documents and real evidence. Evidence is also subject to other classifications, for example: direct, circumstantial, oral, documentary, real, indirect, original, derivative, primary, secondary, prima facie, expert, opinion, confessional, sworn, and unsworn.
2. The body of law regulating the ascertainment of facts in litigation. Evidence law operates to apply rules of proof as a constraint upon the proof of facts in civil and criminal trials. It lays down rules and procedures governing: the adduction of evidence; the exclusion and admissibility of certain types of evidence, such as hearsay; the use of particular kinds of evidence; and the ultimate question of proof.
