Section 15 of Evidence Act "Facts bearing on question whether act was accidental or intentional"
When there is a question whether an act was accidental or intentional, 14[ or done with a particular knowledge or intention,] the fact that such act formed part of a series of similar occurrences, in each of which the person doing the act was concerned, is relevant.
Illustration
(a) A is accused of burning down his house in order to
obtain money for which it is insured.
The facts that a lived in several houses successively, each
of which he insured, in each of which a fire occurred, and
after each of which fires. A received payment from a
different insurance office, are relevant, as tending to show
that the fires were not accidental.
(b) A is employed to receive money from the debtors, of B.
It is A's duty to make entries in a book showing the amounts
received by him. He makes an entry showing that on a
particular occasion he received less than he really did
receive.
The question is, whether this false entry was accidental or
intentional.
The facts that other entries made by A in the same book are
false, and that the false entry is in each case in favor of
A, relevant.
(c) A is accused of fraudulently delivering to B a
counterfeit rupee.
The question is, whether the delivery of the rupee was
accidental.
The facts that, soon before or soon after the delivery to B,
A delivered counterfeit rupees to C, D and E are relevant,
as showing that the delivery to B was not accidental.
