a) Illustration I: Assuming, two Contract Killers make an agreement between themselves to extort money and to kill a wealthy businessman, and accordingly they have extorted money and killed such businessman. Illustration II: A and B made an agreement between themselves, to exchange their wives for some consideration, wherein A has later taken an undue advantage to blackmail B. As per the Section 2(h) of the Indian Contract Act 1872, an agreement which is enforceable by law, is a "Contract". As per the Section 2(g) of the Indian Contract Act 1872, an agreement which is not enforceable by law is said to be void. However the question is, whether the Criminal Courts should necessarily let the those Contract Killers (in the illustration) live scot-free, until the jurisdictional Civil Court decides as to whether the agreement (between those two Contract Killers to extort & kill the businessman) is valid or void?
