LEGAL PRINCIPLES: (1) The concept of joint liability comes under section 34 of IPC which states that "when a criminal act is done by several persons, in furtherance of the common intention of all, each of such persons is liable for that act in the same manner as if it were done by him along."
(2) A person abets an offence, who abets either the commission of an offence, or the commission of an act which would be an offence, if committed by a person capable by law of committing an offence with the same intention or knowledge as that of the abettor.
(3) A criminal conspiracy takes place when two or more people get together and plan to commit a crime and then take some action toward carrying out that plan. The action taken does not have to be a crime itself to further the conspiracy.
