Dishonour of cheque criminalises issuing unpaid cheques, imposing imprisonment or fine where statutory notice and presentation conditions are unmet. Dishonour of a cheque for insufficiency of funds or exceeding agreed arrangement is an offence when drawn for discharge of a legally enforceable debt or liability and returned unpaid; the drawer is punishable by imprisonment, fine, or both. Offence attaches only if the cheque was presented within its validity, the payee or holder issues a written demand to the drawer within the prescribed time after receiving bank notice of dishonour, and the drawer fails to pay within the subsequent prescribed period.
