IPC-Sec 149 Mizaji v. State of U.P., AIR 1959 SC 572, "The first part of Section 149 IPC means that the offence committed in prosecution of the common object must be one which is committed with a view to accomplish the common object. It is not necessary that there should be a preconcert in the sense of a meeting of the members of the unlawful assembly as to the common object; it is enough if it is adopted by all the members and is shared by all of them. In order that the case may fall under the first part, the offence committed must be connected immediately with the common object of the unlawful assembly of which the accused were members. Even if the offence committed is not in direct prosecution of the common object of the assembly, it may yet fall under Section 149 if it can be held that the offence was such as the members knew was likely to be committed. The expression 'know' does not mean a mere possibility, such as might or might not happen. Though it can be said that when an offence is committed in prosecution of the common object, it would generally be an offence which the members of the unlawful assembly knew was likely to be committed in prosecution of the common object that does not make the converse proposition true; there may be cases which would come within the second part but not within the first. The distinction between the two parts of Section 149 Indian Penal Code cannot be ignored or obliterated. In every case it would be an issue to be determined whether the offence committed falls within the first part of Section 149 as explained above or it was an offence such as the members of the assembly knew to be likely to be committed in prosecution of the common object and falls within the second part."
