Facts not otherwise relevant are relevant -
(1) if they are inconsistent with any fact in issue or relevant fact;
(2) if by themselves or in connection with other facts they make the existence or non-existence of any fact in issue or relevant fact highly probable or improbable.
Illustrations
(a) The question is, whether A committed a crime at Calcutta on a certain day.
The fact that, on that day, A was at Lahore is relevant.
The fact that, near the time when the crime was committed, A was at a distance from the place where it was committed, which would render it highly improbable, though not impossible, that he committed it, is relevant.
(b) The question is, whether A committed a crime.
The circumstances are such that the crime must have been committed either by A, B, C or D. Every fact which shows that the crime could have been committed by no one else, and that it was not committed by either B, C or D, is relevant.
