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.

Illustration.

   (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.
