Section 10 of Evidence Act "Things said or done by conspirator in reference to common design"
Where there is reasonable ground to believe that two or more persons have conspired together to commit an offence or an actionable wrong, anything said, done or written by any one of such persons in reference to their common intention, after the time when such intention was first entertained by any one of them, is a relevant fact as against each of the persons believed to be so conspiring, as well for the purpose of proving the existence of the conspiracy as for the purpose of showing that any such person was a party to it.
Illustration
Reasonable ground exists for believing that A has joined in
a conspiracy to wage war against the 11[ Government of
India]
The facts that B procured arms in Europe for the purpose of
the conspiracy, C collected in Calcutta for a like object D
persuaded persons to join the conspiracy in Bombay, E
published writings advocating the object in view at Agra,
and F transmitted from Delhi to G at Kabul the money which C
had collected at Calcutta , and the contents of a letter
written by H giving an account of the conspiracy, are each
relevant, both to prove the existence of the conspiracy, and
to prove As complicity in it, although he may have been
ignorant of all of them, and although the persons by whom
they were done were strangers to him, and although they may
have taken place before he joined the conspiracy or after he
left it.
