The difference between common intention and common object may be stated as under:
1. Under Section 34 number of person must be more than one. Under Section 149 number of persons must be five or more.
2. Section 34 does not create any specific offence but only states a rule of evidence. Section 149 creates a specific offence.
3. Common intention required under Section 34 may be of any type. Common object under Section 149 must be one of the objects mentioned inSection 141.
4. Common intention under Section 3 requires prior meeting of minds or pre- arranged plan, i.e. all the accused persons must meet together before the actual attack participated by all takes place. Under Section 149, prior meeting of minds is not necessary. Mere membership of an unlawful assembly at
the time of commission of the offence is sufficient.
5. Under Section 34 some active participation is necessary, especially in a crime involving physical violence. Section 149 does not require active participation and the liability arises by reason of mere membership of the unlawful assembly with a common object.
