Le contre-interrogatoire selon la règle de Dunn : À lire.
 In Browne v. Dunn, Lord Herschell, L.C., explained that if a party intended to impeach a witness called by an opposite party, the party who seeks to impeach must give the witness an opportunity, while the witness is in the witness box, to provide any explanation the witness may have for the contradictory evidence: Browne v. Dunn, pp. 70-71; R. v. Henderson (1999), 134 C.C.C. (3d) 131 (Ont. C.A.), at p. 141; and R. v. McNeill (2000), 144 C.C.C. (3d) 551 (Ont. C.A.), at para. 44.
 The rule in Browne v. Dunn, as it has come to be known, reflects a confrontation principle in the context of cross-examination of a witness for a party opposed in interest on disputed factual issues. In some jurisdictions, for example in Australia, practitioners describe it as a “puttage” rule because it requires a cross-examiner to “put” to the opposing witness in cross-examination the substance of contradictory evidence to be adduced through the cross-examiner’s own witness or witnesses.
The witness is alerted that the cross-examiner intends to impeach his or her evidence and given a chance to explain why the contradictory evidence, or any inferences to be drawn from it, should not be accepted: R. v. Dexter, 2013 ONCA 744, 313 O.A.C. 226, at para. 17; Browne v. Dunn, at pp. 70-71.
Without the rule, the trier of fact would be deprived of information that might show the credibility impeachment to be unfounded and thus compromise the accuracy of the verdict.
