General Principles

A collateral fact is a "fact not directly connected" or not relevant to "the issue in dispute"[1] The collateral fact rule prohibits the admission of any evidence that would tend to contradict any previously admitted collateral evidence. Any extrinsic contradictory evidence that brings a witness's credibility into question may not be considered where the contradictory evidence not relevant to an issue at trial.[2] When a witness speaks to a fact, the veracity of the testimony can only be brought into question where it is sufficiently material to a trial issue. Otherwise, it will fall up against the collateral fact rule that prohibits the calling of contradictory evidence on immaterial facts. Thus, testimony on collateral issues is conclusive. This rule has been codified in certain legislation including s. 10 and 11 of the CEA.

Collateral evidence is also characterized as evidence which derives its relevance only from the fact that it is admitted for the purpose of contradicting other evidence and nothing else.[3]

A foundational test for collateral fact is whether the evidence contradicting the statement of the witness could be validly led as evidence on its own.[4] Thus, statements to evidence that is not directly connected to a material fact cannot be contradicted.[5]

The rule equally applies in cases that turn on credibility.[6]

Exceptions to the Rule

Exceptions exists for certain evidence going to credibility:[1]

  • existence of material previous statement[2]
  • prior convictions
  • honesty or history of lying
  • bias or partiality[3]
  • motive to fabricate[4]
  • bad reputation
  • perception
  • memory
  • ability to communicate.

Where a witness denies having an animus against the accused at the time of the offence may be contradicted with extrinsic evidence. However, where a witness concedes having an animus against the accused at the time of the offence, they may be cross-examined on an ongoing animus including at the time of trial. [5]

A collateral answer to a question does not prohibit otherwise valid cross-examination on this issue.[6]

Mental or Physical Disorders

A party may violate the collateral fact rule in presenting medical evidence to establish that by some mental or physical illness, the witness is incapable of giving reliable evidence, whether due to delusion or otherwise.[7]
