Explain the presumption as per Section 146 of the Negotiable Instruments Act, 1881 about dishonour of a cheque.

Section 146 of the Negotiable Instruments Act, 1881, inserted by the Amendment Act of 2002, is a compact but powerful provision. It reads: "The Court shall, in respect of every proceedings under this Chapter, on production of bank's slip or memo having thereon the official mark denoting that the cheque has been dishonoured, presume the fact of dishonour of such cheque, unless and until such fact is disproved." The section, in its brevity, achieves something of great practical importance — it spares the courts, the complainants, and the banking system from an enormous procedural burden.

The Problem Section 146 Was Designed to Solve

Before the 2002 Amendment, a complainant under Section 138 was required to prove the factum of dishonour — that is, the actual non-payment of the cheque by the drawee bank — through positive evidence. This invariably meant summoning a bank official to the witness box to formally prove the cheque return memo issued by the bank. Given the sheer volume of Section 138 cases flooding criminal courts across the country, this requirement became a serious impediment. Bank officials were dragged into courts repeatedly, disrupting banking operations and causing delays. Section 146 was introduced precisely to address this mischief. As the Statement of Objects and Reasons accompanying the 2002 Amendment made clear, the entire thrust of the amendment was towards expeditious disposal of cheque dishonour cases, and Section 146 was one of the instruments designed to achieve that objective.

The Nature of the Presumption

Section 146 creates a mandatory statutory presumption — and it is important to appreciate what this means in practice. The word "shall" in the section is not permissive; it is imperative. The moment the complainant produces the bank's return slip or memo bearing the official mark of dishonour, the court has no discretion but to presume that the cheque was, in fact, dishonoured. The court is not entitled to wait for further proof of dishonour, nor can it demand the attendance of a bank official before accepting the fact of dishonour. Production of the document itself becomes the proof.

The presumption under Section 146 is, in its character, a presumption of fact — it is a legal shortcut that treats the bank's official record as conclusive evidence of dishonour, unless the opposite party steps in to disprove it. It operates at the threshold of the trial stage, giving the complainant an immediate evidentiary advantage as soon as the dishonour memo is placed before the court.

What "Official Mark" Means

The phrase "official mark denoting that the cheque has been dishonoured" is the operative heart of the provision. The dishonour memo or return slip must bear the seal of the bank and must carry an endorsement — such as "funds insufficient," "refer to drawer," "account closed," or "stop payment" — to indicate that the cheque has not been honoured. The Bombay High Court, in Tejendrasingh S/O Gopalsingh Bagga v Ravindrakumar (2019 SCC Online Bom 60), held emphatically that if the bank memo does not bear the official seal of the bank, the presumption under Section 146 does not arise at all. This makes sound sense — the section is designed to give legal sanctity to authentic bank records; an unsupported document without the bank's official endorsement cannot receive that protection.

A Rebuttable Presumption — The Accused's Right to Disprove

The presumption under Section 146, however, is not absolute. The section itself says "unless and until such fact is disproved." These words preserve the accused's right to lead evidence before the court to show that the cheque was, in fact, not dishonoured or that the bank memo is unreliable, forged, or otherwise not authentic. This is a narrow but real safeguard. In cases where the accused disputes the genuineness of the return memo, he may summon the concerned bank official and place the bank records before the court to disprove the factum of dishonour. Thus, while Section 146 shifts the initial burden of proving dishonour away from the complainant, it does not shut the door of the court against the accused who has a genuine and specific ground to challenge the document.

Section 146 in the Larger Evidentiary Architecture

Section 146 does not stand alone. It forms part of a trio of evidentiary provisions — Sections 139, 145, and 146 — that collectively equip the complainant with a powerful set of presumptions. While Section 139 raises the presumption that the cheque was issued for a legally enforceable debt or liability, and Section 145 enables the complainant to give evidence by way of affidavit instead of oral deposition, Section 146 completes the picture by presuming the very foundation of the prosecution's case — that the cheque was dishonoured.

Read together, these provisions mean that once a complainant files a properly constituted complaint with the dishonour memo, affidavit of evidence, and proof of notice and non-payment, a formidable legal edifice stands in his favour even before the accused has uttered a word. The burden then shifts entirely to the accused, who must rebut these presumptions by leading evidence that creates reasonable doubt, on the standard of preponderance of probabilities, as the Supreme Court reaffirmed in Basalingappa v Mudibasappa (2019 5 SCC 418).

Practical Significance — Bank Officials Need Not Attend as Witnesses

One of the most practically significant consequences of Section 146 is that in the ordinary run of cases, the complainant need not summon the bank official to prove dishonour. The Bombay High Court, in the context of transferring cases, acknowledged in Baban Motiramji Mohod v State of Maharashtra (III 2007 BC 439) that in view of Section 146, bank officials may not even need to be examined at trial, making the litigation more efficient and less burdensome on the banking system. The section thus reflects the legislature's clear appreciation that banks are not mere parties to these disputes — they are institutional witnesses whose time is valuable and whose presence in every Section 138 case would be not only impractical but disruptive to the banking system as a whole.

In this sense, Section 146 is more than a rule of evidence. It is a statement of legislative policy — a recognition that in the age of computerised banking records, an officially endorsed cheque return memo is as reliable as the oral testimony of any bank official, and that the law must reflect commercial reality rather than cling to archaic rules of proof.
