s 10 Things said or done by conspirator in reference to common design
10. Where there is reasonable ground to believe that 2 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.Illustrations Reasonable ground exists for believing that A has joined in a conspiracy to wage war against the Government. The facts that B procured arms in Europe for the purpose of the conspiracy, C collected money in Malacca for a like object, D persuaded persons to join the conspiracy in Province Wellesley, E published writings advocating the object in view at Singapore, and F transmitted from Singapore to G at Jakarta the money which C had collected at Malacca, 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 A’s complicity in it, although A may have been ignorant of all of them, and although the persons by whom they were done were strangers to A, and although they may have taken place before A joined the conspiracy or after A left it.
