Hearsay and Expert Evidence

Two evidentiary frameworks anchor Canadian trial law. Mohan (1994) governs admissibility of expert evidence: relevance, necessity, no exclusionary rule, properly qualified expert — refined by White Burgess (2015) which makes impartiality a precondition. Khelawon (2006) governs hearsay: necessity and threshold reliability (procedural and/or substantive), with ultimate reliability for the trier of fact.
