43. while appreciating the evidence of a witness, minor discrepancies on trivial matters, which do not affect the core of the case of the prosecution, must not prompt the court to reject the evidence thus provided, in its entirety. The irrelevant details which do not in any way corrode the credibility of a witness, cannot be labelled as omissions or contradictions. Therefore, the courts must be cautious and very particular in their exercise of appreciating evidence. The approach to be adopted is, if the evidence of a witness is read in its entirety, and the same appears to have in it, a ring of truth, then it may become necessary for the court to scrutinise the evidence more particularly, keeping in mind the deficiencies, drawbacks and infirmities pointed out in the said evidence as a whole, and evaluate them separately, to determine whether the same are completely against the nature of the evidence provided by the witnesses, and whether the validity of such evidence is shaken by virtue of such evaluation, rendering it unworthy of belief.
