La définition de la crédibilité par la Cour suprême

White v. The King, [1947] S.C.R. 268

It is a matter in which so many human characteristics, both the strong and the weak, must be taken into consideration. The general integrity and intelligence of the witness, his powers to observe, his capacity to remember and his accuracy in statement are important. It is also important to determine whether he is honestly endeavouring to tell the truth, whether he is sincere and frank or whether he is biassed, reticent and evasive. All these questions and others may be answered from the observation of the witness’ general conduct and demeanour in determining the question of credibility.
