essence of a criminal conspiracy is the unlawful combination and ordinarily the offence is complete when the combination is framed. From this, it necessarily follows that unless the statute so requires, no overt act need be done in furtherance of the conspiracy, and that the object of the combination need not be accomplished, in order to constitute an indictable offence. Law making conspiracy a crime, is designed to curb immoderate power to do mischief which is gained by a combination of the means. The encouragement and support which co-conspirators give to one another rendering enterprises possible which, if left to individual effort, would have been impossible, furnish the ground for visiting conspirators and abettors with condign punishment. The conspiracy is held to be continued and renewed as to all its members wherever and whenever any member of the conspiracy acts in furtherance of the common design. (See American Jurisprudence, Vol. II, Sec. 23, p. 559.) For an offence punishable under Section 120-B, the prosecution need not necessarily prove that the perpetrators expressly agreed to do or caused to be done an illegal act; the agreement may be proved by necessary implication. The offence of criminal conspiracy has its foundation in an agreement to commit an offence. A conspiracy consists not merely in the intention of two or more, but in the agreement of two or more to do an unlawful act by unlawful means. So long as such a design rests in intention only, it is not indictable. When two agree to carry it into effect, the very plot is an act in itself, and an act of each of the parties, promise against promise, actus contra actum, capable of being enforced, if lawful, punishable if for a criminal object or for use of criminal means.”
