Once the execution of cheque is admitted Section 139 of the Negotiable Instruments Act mandates a presumption that the cheque was for the discharge of any debt or other liability. The presumption under Section 139 is a rebuttable preumption and the onus is on the accused to raise the probable defence. The standard of proof for rebutting the presumption is that of preponderance of probabilities.
To rebut the presumption, it is open for the accused to rely on evidence led by him or the accused can also rely on the materials submitted by the complainant in order to raise a probable defence. Inference of preponderance of probabilities can be drawn not only from the materials brought on record by the parties but also by reference to the circumstances upon which they rely.
It is not necessary for the accused to come in the witness box in support of his defence, Section 139 imposed an evidentiary burden and not a pervasive burden.
