1. Legal Framework of Digital Evidence in Banking Litigation

India - Three Overlapping Laws:

A. Indian Evidence Act, 1872 (Now Bharatiya Sakshya Adhiniyam, 2023):

• Section 65B (Old) / Section 63 BSA (New): Computer output is secondary evidence. Admissible only with certificate.

Requirement of a certificate is a pre-condition to the admissibility of evidence by way of electronic record under Section 65-B of the Act... In the absence of such certificate, a party cannot let in electronic evidence and it is per se inadmissible

B. Bankers' Books Evidence Act, 1891 (BBEA) - Special Law for Banks:
This is the game changer for banks.

It is settled position of law that a special law will always prevail over the general law. Therefore, provisions of Bankers' Books Act, shall apply in case of bank records maintained in electronic forms. Provisions of section 65 B of the Indian Evidence Act shall not apply in such cases.

• Section 2(8) + Section 2A BBEA: Banking records maintained in electronic forms are admissible in evidence. Includes ledgers, day-books, cash-books, account books, and all records used in ordinary business of bank, whether in physical or electronic form including printouts.
• Section 4 BBEA: Certified copy of entry in banker's books shall be prima facie evidence.

C. Information Technology Act, 2000:

• Section 4 - Legal recognition of electronic records
• Section 5 - Legal recognition of digital signatures
• Section 65B Evidence Act is pari materia to Section 2A BBEA. Therefore they should be construed together.

US / UK Parallel:
US: Federal Rules of Evidence 901(b)(9) - Evidence generated by system/process; FRE 902(13) - Certified records generated by electronic process self-authenticating. Bank records under business records exception FRE 803(6).
UK: Civil Evidence Act 1995, Bankers' Books Evidence Act 1879 (UK origin).

2. What Counts as Digital Evidence in Banking Cases?

1. Core Banking System (CBS) data: Account statements, ledgers
2. Electronic Fund Transfers: NEFT/RTGS/IMPS logs, UPI, SWIFT MT messages
3. Digital Channels: Net banking logs, mobile app logs, IP address, device ID, OTP delivery logs, ATM / CCTV footage
4. Communications: Email approvals, SMS alerts, call recordings
5. Blockchain / Crypto: Exchange ledgers for crypto banking cases

All are vulnerable because computer outputs are susceptible to tampering, alteration, transposition and excision and a whole trial based on them could lead to a travesty of justice

3. Landmark Case Laws - The Trinity That Every Bank Lawyer Must Know

CASE 1: Anvar P.V. vs P.K. Basheer (2014) 10 SCC 473 - Overruled Parliament Attack Case

Facts: Election petition, CDs containing video of election speeches.

Supreme Court Held:

An electronic record by way of secondary evidence shall not be admitted in evidence unless the requirements under Section 65B are satisfied. Thus, in case of CD, VCD, chip, etc., the same shall be accompanied by the certificate in terms of Section 65B obtained at the time of taking the document, without which, the secondary evidence pertaining to that electronic record, is inadmissible.

Overruled State (NCT of Delhi) v Navjot Sandhu alias Afsal Guru (2005) - Parliament Attack case - which had admitted electronic evidence without certificate.

Impact on Banking: Banks started losing loan recovery cases because branch manager produced statement printout without 65B certificate.

CASE 2: Arjun Panditrao Khotkar vs Kailash Kushanrao Gorantyal (2020) 7 SCC 1 - 3-Judge Bench Clarifies Anvar

Facts: Election cases, conflicting views between Anvar and Shafhi Mohammad.

Supreme Court Finally Held:

1. Certificate under Section 65B(4) is a condition precedent to admissibility - mandatory.
2. Oral evidence in place of such certificate cannot possibly suffice.
3. Certificate can be produced at any stage if trial not concluded, and if person giving certificate not available, certificate can be given by person in charge of computer.
4. If electronic record is primary evidence (original device itself produced), certificate not required.

Banking Relevance: In DRT/SARFAESI proceedings, banks now produce 65B certificate from IT officer or Branch Manager who is in charge of computer system.

Template upheld in Khotkar:
(a) Identification of electronic record
(b) Description of device/computer producing it
(c) Details of compliance with 65B(2) - computer was regularly used, regularly fed information in ordinary course, functioning properly
(d) Signature of person in charge

CASE 3: Bankers' Books vs Evidence Act - The Exception

Radheshyam G. Garg vs State, Raquib Ansari vs Udayveer Singh (Delhi HC 24 April 2023)

Banking records maintained in electronic forms are admissible... Bankers' Books Evidence Act shall apply... provisions of section 65B shall not apply. It is settled that special law will always prevail over general law. Concerning admissibility of banking records in electronic form, Section 2A of Bankers' Books Evidence Act would be considered instead of Section 65B.

Facts: Loan recovery, bank filed statement under BBEA certificate, defendant argued no 65B certificate.

Delhi High Court held: For banks, Section 2A BBEA certificate (certified by principal accountant or branch manager) is sufficient. No need for 65B certificate. BBEA is special law.

Conditions under BBEA Section 2A Certificate:

• Printout is true copy of entry in books ordinarily kept by bank
• Such books were maintained in ordinary course of business
• Books were in custody and control of bank
• Certified by officer with name and designation

This is why all banks now produce two certificates: One under BBEA (for banking entries) + One under 65B (for net banking logs, OTP logs which are NOT part of "books").

CASE 4: Abdul Rahman Kunji vs State of West Bengal (Cal HC) - What is "Bankers Books"?

Court held: Email approval for loan is NOT part of bankers books, must prove through 65B. Only ledgers, day books, cash books, account books qualify. WhatsApp chat between RM and customer - 65B required, not BBEA.

CASE 5: Supreme Court on Electronic Bank Statements - Sonu vs State of Haryana (2017) 8 SCC 570

Clarified: If original electronic record is produced as primary evidence (e.g., hard disk of bank server seized), no certificate needed. But if printout produced as secondary, certificate mandatory.

CASE 6: International - US & UK

US - Lorraine v Markel (2007) - Most cited US case: Court laid 5-step test for admissibility of digital evidence - relevance, authenticity, hearsay, best evidence, probative vs prejudicial. Banking email must be authenticated via hash value.

UK - R v Brown (2011): ATM logs admissible under business records exception, but need to show system reliability.

4. Practical Compliance - How Banks Must Prepare Evidence Today

For Litigation / DRT / SARFAESI:

1. For Statement of Account: Certificate under Section 2A BBEA signed by Branch Manager / Principal Accountant. Format prescribed in Act.
2. For Digital Trail (Netbanking IP, OTP, UPI logs): Separate 65B certificate under Section 63 BSA from System Administrator / IT Officer in charge of CBS server, with hash value, server details, audit logs.
3. Certificate Timing: Obtain at time of taking printout, not 2 years later at trial. Khotkar allows late production but DRT judges still penalize delay.
4. Chain of Custody: Preserve original logs, audit trail showing no tampering, SOC reports.
5. Video Conferencing / Email Approvals: 65B + 88A Evidence Act (presumption for electronic messages).

Failure = Fatal: Supreme Court has warned Banks will ignore at their own peril a Supreme Court ruling that electronic records without proper safeguards are non-admissible as evidence.

In recent DRT cases 2024-25, loan recovery claims of Rs 50cr+ dismissed because bank produced CBS printout without BBEA certificate.
