Entries in books of account without corroborative evidence cannot establish liability in commercial suits.

The Appellant, proprietor of "Vishal Fastener," filed a commercial suit for the recovery of ₹5,23,999/- against the Respondent for goods (washers) supplied between April 2022 and March 2023.

The Appellant relied on six specific invoices totaling ₹11,56,721/- and a ledger account.

The Respondent contended that the goods were defective/belated and claimed that the entire amount for the six invoices had already been paid, including an advance of ₹3,94,941/-.

The Trial Court found that while the Respondent failed to prove the goods were defective, the Appellant’s own ledger showed that the Respondent had paid ₹13,93,549/- between April 2022 and June 2023, which exceeded the value of the six subject invoices by ₹2,36,828/-.

The Trial Court dismissed the suit.

The Appellant appealed, seeking to introduce additional evidence (prior invoices and GST filings) to explain that the payments were adjusted against an older opening balance of ₹8,83,327/-.

1. Whether the ledger account (Ex.PW-1/C) constituted sufficient evidence to establish a liability of ₹5,23,999/- in the absence of supporting invoices for the opening balance.

2. Whether the Appellant met the "reasonable cause" threshold under Order XI Rule 1(5) of the CPC (as amended by the Commercial Courts Act) and the criteria under Order XLI Rule 27 of the CPC to introduce additional documents at the appellate stage.

Section 34 of the Indian Evidence Act, 1872, which stipulates that entries in books of account alone are insufficient to charge a person with liability without corroborative evidence.

The court relied on Chandra Dhar Goswami v. Gauhati Bank Limited and Harish Mansukhani v. Ashok Jain to affirm that delivery of goods must be proved independently of ledger entries.

Order XI Rule 1(5) of the CPC (Commercial Courts Act), which bars the introduction of documents in a commercial suit not disclosed with the plaint unless "reasonable cause" is shown.

Order XLI Rule 27 of the CPC and the principles from Union of India v. Ibrahim Uddin, holding that additional evidence in appeal is an exception, not a right, and "wrong advice of a pleader" does not constitute "substantial cause".

The Court observed that the Appellant’s claim was specifically predicated on six invoices, and the Trial Court correctly found that the payments made during the relevant period covered these invoices in full.

Regarding the "opening balance" mentioned in the ledger, the Court held that entries in a ledger are not self-probative; since the Appellant failed to produce or prove invoices corresponding to that opening balance during the trial, no liability could be fastened on the Respondent based on those entries alone.

Regarding the application for additional evidence, the Court noted that the documents (GST filings and prior invoices) were always in the Appellant's possession.

The Appellant’s excuse—that he followed his counsel’s advice not to file them—was rejected as it would render the strict disclosure requirements of the Commercial Courts Act meaningless.

The Court found no "substantial cause" to allow the evidence, as it would require entertaining new foundational pleadings not present in the original plaint.

The application for additional evidence (CM No. 42158/2025) was dismissed as the Appellant failed to show "reasonable cause" or "due diligence"; consequently, the appeal was dismissed, affirming the Trial Court's judgment.
