A criminal conspiracy is generally hatched in secrecy, owing to which, direct evidence is difficult to obtain. The offence can therefore be proved either by adducing circumstantial evidence, or by way of necessary implication. However, in the event that the circumstantial evidence is incomplete or vague, it becomes necessary for the prosecution to provide adequate proof regarding the meeting of minds, which is essential in order to hatch a criminal conspiracy, by adducing substantive evidence in the court. Furthermore, in order to constitute the offence of conspiracy, it is not necessary that the person involved has knowledge of all the stages of action. In fact, mere knowledge of the main object/purpose of conspiracy, would warrant the attraction of relevant penal provisions. Thus, an agreement between two persons to do, or to cause an illegal act, is the basic requirement of the offence of conspiracy under the penal statute. R. Shaji v. State of Kerala, (2014) 4 SCC (Cri) 185.
