Cheque bounce cases arise when a cheque is dishonored by the bank due to insufficient funds, mismatch of signatures, or closure of account. Such matters are governed by Section 138 of the Negotiable Instruments Act, 1881. The law provides a legal remedy to the payee against the drawer of the cheque. The process involves issuing a legal notice within a prescribed time after dishonor, demanding payment. If the payment is not made within the statutory period, a criminal complaint may be filed before the court. Cheque bounce cases aim to maintain financial discipline and trust in commercial transactions. Courts may impose penalties including fine, compensation, or imprisonment. Timely legal action and proper adherence to statutory timelines are crucial in such cases.
