Common intention implies a pre-arranged plan and acting in concert pursuant to the plan. Common intention comes into being prior to the commission of the act, which need not be a long gap. To bring common intention into effect a pre-concert is not necessarily be proved, but it may well develop on the spot as between a number of persons and could be inferred from facts and circumstances of each case. For example A and B caught hold of C where only B stabbed C with a knife but A is also liable for murder as there was a pre concerted action. In the case Pandurang v. State of Hyderabad, Supreme court emphasized on this point that prior concert need not be something always very much prior to the incident, but could well be something that may develop on the spot, on the spur of the moment.

Common Intention and Similar Intention

Common intention does not mean similar intention of several persons. To constitute common intention it is necessary that the intention of each one of them be known to the rest of them and shared by them. In the case of Dukhmochan Pandey v. State of Bihar, the Supreme Court, held that: “Common intention which developed at the spur of the moment is different from the similar intention actuated a number of person at the same time....the distinction between a common intention and similar intention may be fine, but is nonetheless a real one and if overlooked, may lead to miscarriage of justice....” The mere presence of accused together is not sufficient to hold that they shared the common intention to commit the offence
in question. It is necessary that the intention of each one of 'several persons‘ be known to each other for constituting common intention.
