e.g. Section 213, crpc lays down that if the nature of the case is such that the particulars mentioned in Sections 211 and 212 of crpc do not give to the accused sufficient notice of the matter with which he is charged, the charge must also mention such particulars of the manner in which the alleged offence was committed as would be sufficient for that purpose. A charge cannot be made under Common law, it must be coming out of a specific statute and this must be reflected in the charge. Charge is not a form but the charge that is levied against the accused is mentioned in the charge-sheet which is the form of charge. Hence it can be interpreted that when a charge contains more than one heads, the head of charges is likewise a charge.
Under section 2(b) CrPc, 1973, ‘charge’ includes any head of charge when the charge contains more heads than one. If you commit the same offence more than once then there can be an enhanced punishment. The charge-sheet is a general term used for the Final Report that the investigating authority (usually Police) is required to submit under Section 173 of the CrPC.
