Yes, electronic evidence such as call records, emails, CCTV footage, or messages can be challenged, most commonly on the ground that it wasn't accompanied by a proper certificate under Section 65B of the Evidence Act (now Section 63 of the Bharatiya Sakshya Adhiniyam), or that its chain of custody wasn't properly maintained, raising doubts about tampering. Courts have been fairly strict about this procedural requirement, and evidence collected or presented without following it can be excluded even if its content otherwise seems damaging. Practically, have your lawyer check every piece of electronic evidence against you specifically for this certification and custody trail, since a technical gap here can significantly weaken the prosecution's case regardless of what the evidence appears to show.

For a detailed review of the electronic evidence in your matter, it is recommended to consult experienced retired judges and seek guidance from Aapka Legal Advice, whose panel can assess whether it can be genuinely challenged.

Yes, electronic evidence can be challenged in a Mumbai criminal case on multiple grounds under the Bharatiya Sakshya Adhiniyam 2023. The most powerful challenge is the absence of a Section 63 BSA certificate — held mandatory by the Supreme Court in Arjun Panditrao Khotkar (2021). Further challenges include broken chain of custody, hash value disputes, and timestamp inaccuracies.

Quick Answer Box

Seven grounds to challenge electronic evidence in Mumbai:

1. Missing Section 63 BSA certificate — most powerful; evidence inadmissible without it
2. Defective certificate — wrong certifier, missing device details, inaccurate description
3. Broken chain of custody — unexplained gap in possession from device to court
4. Hash value mismatch — digital fingerprint shows file has been tampered with
5. Timestamp inaccuracy — recording device clock was not accurately set
6. Device authenticity dispute — seized device is not the device on which content was created
7. Content manipulation — evidence of editing, compression, or alteration

• When to raise: before the document is formally exhibited at trial — not after

Key Takeaways

• Section 63 BSA 2023 (formerly Section 65B IEA) governs the admissibility of electronic records — the certificate under Section 63(4) BSA is mandatory.
• The Supreme Court in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal, (2021) 7 SCC 1 confirmed the certificate is mandatory — overruling Shafhi Mohammad (2018) which had suggested some relaxation.
• Seven distinct grounds exist for challenging electronic evidence — each applicable to different types of digital evidence and at different procedural stages.
• The timing of the objection is critical — challenges to admissibility must be raised when the document is being tendered in evidence, not after it has been marked as an exhibit.
• Admissibility challenges (the evidence should not be admitted) and weight challenges (the evidence is admitted but unreliable) are distinct strategies requiring different arguments.
• WhatsApp evidence, CCTV footage, email, banking records, and call detail records each have specific vulnerability points that differ from one another.
• Hash value verification is both the prosecution's authentication tool and the defence's primary tampering challenge mechanism.
• A formal application for FSL forensic examination can be filed where the defence challenges the authenticity of specific electronic evidence.

1. The Legal Framework for Electronic Evidence in India

Electronic evidence — WhatsApp messages, CCTV footage, emails, banking records, call detail records, social media posts, and data from seized devices — has become the dominant form of evidence in Mumbai criminal cases. Courts, prosecution agencies, and investigating officers routinely rely on digital records to establish facts.

But digital evidence is not infallible. It can be manipulated, misattributed, incorrectly certified, or produced without maintaining the evidentiary requirements that ensure its authenticity. Indian law recognises this — and the Bharatiya Sakshya Adhiniyam (BSA) 2023 provides a specific framework for the admissibility of electronic records that creates multiple challenge opportunities for the defence.

The legal framework has two levels: (a) the admissibility threshold — does the electronic record meet the requirements for being admitted into evidence at all; and (b) the weight question — if admitted, how much evidential value should the court give it. Both levels offer challenge opportunities.

2. Relevant Statutory Provisions

3. The Arjun Panditrao Khotkar Ruling — The Controlling Authority

Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal, (2021) 7 SCC 1 is the Supreme Court's definitive ruling on electronic evidence admissibility. A Constitution Bench held:

• The certificate under Section 65B(4) IEA (now Section 63(4) BSA 2023) is mandatory for the admissibility of electronic records as secondary evidence.
• This certificate cannot be waived. It cannot be dispensed with on the ground that it would be inconvenient to obtain.
• Shafhi Mohammad v. State of Himachal Pradesh (2018) 2 SCC 801 — which had held that the certificate was not mandatory in all cases — was expressly overruled.
• The certificate must be given by a person occupying a responsible official position in relation to the operation of the relevant device.

Practical consequence: any electronic record produced in a Mumbai criminal case without a proper Section 63(4) BSA certificate is vulnerable to a mandatory exclusion objection at the admissibility stage. This applies to the prosecution's electronic evidence — and by the same token, to the defence's electronic evidence.

4. Admissibility Challenge vs. Weight Challenge — The Critical Distinction

Two fundamentally different types of electronic evidence challenges exist:

Admissibility Challenge: Argues that the electronic record should not be admitted into evidence at all — because it lacks the required Section 63 BSA certificate, has a broken chain of custody, or is otherwise fundamentally defective.

Weight Challenge: Accepts that the electronic record has been admitted but argues it should be given little or no evidentiary weight — because the timestamp is unreliable, the content has been selectively produced, the device's integrity is questionable, or independent corroboration is absent.

When each applies:

• Admissibility challenge: raised when the document is being formally tendered in evidence (before exhibition).
• Weight challenge: raised in cross-examination of the witness producing the evidence, and in final arguments.

A well-structured electronic evidence challenge combines both — an admissibility objection as the primary attack, and a weight challenge as the fallback if the admissibility objection is overruled.

5. The Seven Grounds for Challenging Electronic Evidence

6. Ground 1 — Missing Section 63 BSA Certificate

The strongest admissibility challenge. Under Section 63(4) BSA 2023, a certificate must accompany any electronic record produced as secondary evidence. Without this certificate, the electronic record is inadmissible.

How to raise this challenge: When the prosecution witnesses attempt to exhibit (formally produce) an electronic record — printout of WhatsApp messages, CD of CCTV footage, computer-generated banking records — the defence advocate must immediately object:

"Your Honour, we object to the exhibition of this document / electronic record. The prosecution has not produced a certificate under Section 63(4) of the Bharatiya Sakshya Adhiniyam, 2023, as required by the Supreme Court's ruling in Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2021) 7 SCC 1. Without such a certificate, this electronic record is inadmissible."

The objection must be recorded in the proceedings. If the court overrules it, the overruling itself is a ground for appeal.

7. Ground 2 — Defective Certificate

Even where a Section 63 BSA certificate exists, it may be defective — and a defective certificate is legally the same as no certificate.

Common defects in Section 63 BSA certificates:

• Wrong certifier: the certificate is signed by someone who was not in charge of the relevant device — a junior officer signed instead of the custodian; an IT assistant signed instead of the system manager.
• Missing device identification: the certificate does not specify the make, model, serial number, or IMEI of the device from which the record was generated.
• Incorrect device description: the device described in the certificate does not match the device that actually generated the record.
• Missing malfunction statement: the certificate does not state that the device was operating properly (or that any malfunction did not affect the relevant record).
• Missing "ordinary course" statement: the certificate does not state that the record was generated in the ordinary course of activities of the organisation.
• Unsigned or undated: the certificate is not signed and dated by the certifier.

How to challenge: cross-examine the witness who produced the certificate on each defect. Use the Arjun Panditrao requirements as a checklist.

8. Ground 3 — Broken Chain of Custody

Electronic evidence that has passed through multiple hands without documented transfers has a broken chain of custody — an unexplained gap in the documented possession sequence that creates doubt about whether the evidence produced in court is the same evidence originally collected.

A complete chain of custody requires:

• Documentation of initial seizure (mahazar / seizure list).
• Receipt when transferred to FSL or any other entity.
• FSL's acknowledgment and handling record.
• Record of transfer back from FSL to the police.
• Record of production from police to court.

Where to attack chain of custody:

• Compare the mahazar date with the FSL receipt date — any unexplained gap.
• Check whether the seized device's IMEI matches the device whose data was forensically extracted.
• Examine whether the data was stored and transferred on tamper-evident media.

9. Ground 4 — Hash Value Mismatch

A hash value is a unique digital fingerprint generated by running a file through a cryptographic algorithm. If even a single byte of the file is altered, the hash value changes completely.

How hash values are used in electronic evidence: When digital evidence is extracted from a device, a hash value is generated and recorded. If the same algorithm is applied to the file produced in court and the hash value matches the original, the file has not been altered. If it does not match — the file has been altered.

Challenge procedure:

• Apply to the court for forensic examination of the electronic record by the Forensic Science Laboratory.
• The FSL compares the hash value of the produced file with the hash value recorded at extraction.
• If there is a mismatch → the file has been altered → the electronic evidence is unreliable.

When this is most powerful: where the prosecution produced electronic records but did not generate or record hash values at the time of extraction — the absence of hash value documentation is itself a reliability concern.

10. Ground 5 — Timestamp Inaccuracy

Every electronic record bears a timestamp — the date and time embedded in or associated with the file. But timestamps are only as accurate as the generating device's internal clock.

Common timestamp problems:

• CCTV system clocks not synchronised — may be hours or days off.
• Mobile device clocks set to wrong time zone.
• Server clocks not synchronised with NTP (Network Time Protocol) standard.
• WhatsApp timestamps reflecting server time, not local time.

How to challenge timestamps:

• Examine the CCTV system's maintenance records — when was the clock last set?
• Cross-examine the certifier on clock synchronisation.
• Commission FSL examination specifically on timestamp accuracy.
• Cross-reference the timestamp with independent time-anchored events visible in the footage or data.

11. Ground 6 — Device Authenticity Dispute

Where the prosecution claims that a specific device — a specific mobile phone with a specific IMEI — generated a specific electronic record, the defence can challenge whether:

• The device actually belongs to the accused.
• The specific data is from the device and not transferred from another source.
• The device presented in court is the same device seized from the accused.

Challenge procedure:

• Compare the IMEI numbers on the mahazar, the seizure list, and the certificate.
• Check whether the forensic extraction specifically identifies the source device by IMEI and model.
• Challenge the witness on whether they can confirm the produced device is the same device seized.

12. Ground 7 — Content Manipulation or Tampering

Digital video, audio, and text files can be edited, shortened, spliced, compressed, or altered in ways that are not always visually obvious.

Types of manipulation:

• Selective excerpt: producing only part of a conversation that distorts its meaning.
• Video splicing: combining footage from different times or locations.
• Compression artefacts: compression of video that changes apparent content.
• Metadata alteration: changing the metadata (creation date, author, location) of a file.

Challenge procedure:

• Apply for FSL examination specifically for editing or tampering analysis.
• Cross-examine on whether the full original record was produced or only a selected excerpt.
• Challenge whether the original uncompressed format was preserved.

13. Timing of the Objection — The Most Critical Procedural Point

The timing of an electronic evidence challenge is critical and is the aspect most commonly mishandled by inexperienced advocates.

The golden rule: object before exhibition.

When the prosecution witness attempts to formally tender (exhibit) the electronic record before the court — typically by handing the printout to the court officer and asking for it to be marked as an exhibit — the defence must object at that moment, before the exhibit mark is given.

If the document is allowed to be exhibited without objection, the defence may be deemed to have waived the admissibility challenge. The weight challenge remains available, but the powerful admissibility objection is foreclosed.

Procedure at the moment of exhibition:

1. The prosecution witness produces the electronic record.
2. The prosecution advocate asks the court to mark it as an exhibit.
3. The defence advocate immediately rises and states the objection on record.
4. The court considers the objection.
5. If overruled: the exhibit is marked; the defence's objection is recorded for appeal.
6. If sustained: the exhibit is not marked; the electronic record is inadmissible.

14. Device-Specific Challenge Strategies

Each type of electronic evidence has specific vulnerability points:

15. WhatsApp Evidence — Specific Challenges

WhatsApp evidence is the most frequently challenged electronic evidence in Mumbai criminal courts. Specific vulnerabilities:

• Certificate must be from the phone's owner/custodian — not a police officer who subsequently accessed the phone.
• Selective chats: if only selected messages are produced (not the full conversation), the context may be distorted — challenge the selective production.
• Screenshots are particularly vulnerable — a screenshot is a photograph of a screen, not a certified electronic record; challenge whether a screenshot constitutes a "computer output" requiring Section 63 BSA certification.
• End-to-end encryption backup: WhatsApp's encryption means messages can only be extracted from the originating device — if the extraction was from a backup, the chain from backup to production must be documented.
• Deleted message recovery: if messages were recovered through forensic extraction after deletion, the extraction methodology must be certified.

16. CCTV Footage — Specific Challenges

• Timestamp challenge — the most powerful challenge for CCTV; establish that the recording device clock was inaccurate.
• Chain of custody from camera to court — was the footage directly extracted, copied to a CD/DVD, compressed? Each step must be documented.
• Quality enhancement: if the prosecution used software to enhance footage for identification, the enhancement methodology must be disclosed and can be challenged.
• Camera angle and field of view — challenge whether the camera actually captured what the prosecution claims it shows.
• System clock not synchronised — apply for FSL examination of the recording system's clock synchronisation records.

17. Email Evidence — Specific Challenges

• Who certifies email evidence? The email server administrator is the appropriate certifier — not the recipient. If the recipient certifies their own inbox screenshot, this may not satisfy Section 63(4) BSA.
• Email headers — email metadata including routing information can be examined by FSL for authenticity.
• Phishing / spoofing — email "from" addresses can be spoofed; the header analysis reveals the actual source server.
• Selective production — if only selected emails are produced, the full email chain may tell a different story.

18. Banking and Financial Records — Specific Challenges

• Who certifies bank records? An authorised officer of the bank must certify records generated by the bank's computer systems. A police officer who obtained bank records under Section 91 CrPC / Section 94 BNSS cannot certify them.
• System-generated vs. manually prepared records — only system-generated records are "computer outputs"; manually prepared summaries are not.
• Account statement period — ensure the statement covers the relevant period; selectively produced statements can be challenged.

19. Call Detail Records — Specific Challenges

• Telecom operator's authorised signatory must certify CDRs — a police officer cannot be the certifier.
• Tower dumping — where all calls from a specific tower are produced to establish location, challenge the tower's coverage radius and the reliability of cell-tower-based location evidence.
• Time zone alignment — CDR timestamps must be in Indian Standard Time or clearly referenced to another time zone.
• Selective production — if only specific call periods are produced, the full record may undermine the prosecution's narrative.

20. The Forensic Examination Application

Where the defence challenges the authenticity of electronic evidence, an application for FSL forensic examination is available:

Procedure:

1. File an application before the trial court specifying: the electronic record to be examined; the specific authenticity concern (hash value, timestamp, tampering); and the FSL examination requested.
2. The court issues a direction to send the electronic record / device to the FSL.
3. The FSL forensic examiner conducts the examination and produces a report.
4. The FSL report is filed before the court.
5. The forensic examiner is available for cross-examination.

Timing: the forensic examination application should be filed early in the evidence stage — before the prosecution closes its evidence — so the FSL report is available for use in cross-examination of prosecution witnesses and final arguments.

21. Secondary Evidence of Electronic Records

Where the original electronic device is unavailable (lost, destroyed, or beyond the court's reach), Section 65 BSA 2023 allows production of secondary evidence.

Challenges to secondary evidence of electronic records:

• Secondary evidence is generally weaker than primary evidence — the court gives it less weight.
• The prosecution must explain why the original is not available.
• Where the original device exists but has not been produced, the secondary evidence argument is vulnerable to a challenge demanding the production of the original.

22. The Shafhi Mohammad Overruling — Why It Matters

Shafhi Mohammad v. State of Himachal Pradesh, (2018) 2 SCC 801 held that the Section 65B certificate requirement was not mandatory in all cases — a person who was not in possession of the original device could not be expected to provide the certificate.

This holding was expressly overruled by Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal (2021). The Constitution Bench held that the certificate requirement is mandatory without exception.

Why this matters today: if the prosecution produces electronic evidence and cites Shafhi Mohammad to justify the absence of a certificate — or if they rely on the "public records" exception to avoid the certificate requirement — cite Arjun Panditrao and its overruling of Shafhi Mohammad. This is a decisive legal argument.

23. Latest Legal Position (2023–2026)

The Bharatiya Sakshya Adhiniyam (BSA) 2023 replaced the Indian Evidence Act from July 1, 2024. Section 63 BSA mirrors Section 65B IEA; Section 65 BSA mirrors Section 65A IEA. All prior Supreme Court case law — particularly Arjun Panditrao Khotkar — applies directly under the BSA 2023.

The transition date means: for electronic evidence produced in cases before July 1, 2024, the IEA framework applies; for evidence in cases filed or evidence produced after July 1, 2024, the BSA 2023 framework applies. Both require a certificate of authenticity — the requirement is the same, the section number differs.

24. Landmark Supreme Court Judgments

• Arjun Panditrao Khotkar v. Kailash Kushanrao Gorantyal, (2021) 7 SCC 1 — mandatory certificate; overruled Shafhi Mohammad; the controlling authority.
• Anvar P.V. v. P.K. Basheer, (2014) 10 SCC 473 — Section 65B certificate mandatory; electronic records without certificate inadmissible; the first clear statement of the mandatory requirement.
• Shafhi Mohammad v. State of Himachal Pradesh, (2018) 2 SCC 801 — had relaxed the certificate requirement; overruled by Arjun Panditrao.
• Tomaso Bruno v. State of U.P., (2015) 7 SCC 178 — CCTV evidence in criminal trial; identification from footage; courts must examine footage carefully.
• State (NCT of Delhi) v. Navjot Sandhu, (2005) 11 SCC 600 — early statement on electronic evidence; call records; admissibility principles.

25. Bombay High Court Position

The Bombay HC:

• Applies the Arjun Panditrao mandatory certificate requirement strictly.
• Has upheld objections to WhatsApp evidence and CCTV evidence that lacked proper Section 63 BSA / Section 65B IEA certificates.
• Has directed FSL examination of disputed electronic evidence in appropriate cases.
• Has admitted challenges to timestamp accuracy in CCTV evidence and directed verification.
• Has set aside convictions on appeal where the trial court relied on uncertified electronic evidence despite a formal objection.

26. How to Prepare an Electronic Evidence Challenge

Before the evidence stage begins:

• Obtain all prosecution documents filed with the chargesheet — identify every electronic record.
• For each electronic record: check whether a Section 63 BSA certificate is attached.
• If certificate exists: check for all seven defects listed in Ground 2.
• If certificate is absent or defective: prepare the objection script for exhibition day.

Prepare a challenge matrix:

27. Documents Required for the Challenge

• Copy of every electronic record produced by the prosecution (from the chargesheet annexures or subsequently produced).
• Section 63 BSA certificates (if produced) for each electronic record.
• Mahazar / seizure list for seized electronic devices.
• FSL examination application (drafted by advocate).
• Cross-examination plan for the witness producing each electronic record.

28. Timeline of Electronic Evidence Challenges

29. Costs Involved

• Objection to exhibition: no court fee; part of trial advocacy.
• FSL examination application: nominal court fee; advocate's drafting fee.
• Private digital forensic expert (if needed to prepare the challenge): varies by expert.
• Appeal on wrongly admitted electronic evidence: Sessions Court / Bombay HC fees.

30. Common Mistakes in Challenging Electronic Evidence

• Not raising the objection at exhibition — waiting until final arguments to challenge admissibility; by then the objection may be waived.
• Not checking the certificate for all seven defects — challenging only the absence of a certificate while missing a defective certificate issue.
• Citing Shafhi Mohammad — overruled; never cite it as authority.
• Not filing the FSL examination application early — leaving insufficient time for the FSL report to be produced before the close of prosecution evidence.
• Not noting the objection on the record — an oral objection without being placed on record cannot be raised in appeal.
• Not challenging all electronic records — focusing on one piece of electronic evidence while missing others.

31. Risks and Limitations

• Even if an admissibility objection is raised correctly, the trial court may overrule it — the record is preserved for appeal but the evidence is admitted.
• Weight challenges require effective cross-examination — an advocate unfamiliar with digital forensics may not exploit vulnerabilities effectively.
• FSL examinations take 1–3 months — this adds time to the evidence stage.
• Where the prosecution has a genuinely strong Section 63 BSA certificate and documented chain of custody, the challenge is more difficult.
• Some courts are still unfamiliar with BSA 2023 terminology (citing old IEA section numbers) — the advocate must be prepared to cite both.

32. Practical Legal Advice

Electronic evidence challenges are highly technical — they require an advocate who understands both the legal framework (Arjun Panditrao, Section 63 BSA) and the technical concepts (hash values, chain of custody, timestamp accuracy). The most common failure in electronic evidence challenges is an advocate who knows the legal framework but cannot effectively cross-examine on the technical issues.

The challenge must be prepared before the evidence stage begins — not improvised at the moment the prosecution attempts to exhibit the document.

33. Litigation Strategy

• Build a challenge matrix for every electronic record in the prosecution's case before the evidence stage begins.
• Raise admissibility objections at the moment of exhibition — never after.
• File the FSL examination application early in the evidence stage.
• Prepare a dedicated cross-examination plan for the certifying witness.
• Combine admissibility challenge with weight challenge as belt-and-suspenders.
• In final arguments, cite Arjun Panditrao on each improperly certified electronic record and invite the court to disregard it.
• If the trial court wrongly admits electronic evidence despite objection, preserve the record meticulously for appeal.

34. Step-by-Step Action Plan

• On receipt of prosecution documents: identify all electronic records; check each for Section 63 BSA certificate.
• Certificate assessment: check each certificate for the seven possible defects.
• Prepare challenge matrix: one row per electronic record; one column per challenge ground.
• FSL application: draft and file before the prosecution closes its evidence.
• Cross-examination preparation: prepare specific questions for the certifying witness on certificate defects, chain of custody, and technical issues.
• At exhibition moment: raise the admissibility objection on record; ensure it is noted.
• After prosecution closes: file weight challenge submissions and no-case motion if applicable.
• Final arguments: systematic electronic evidence challenge using the challenge matrix as the structure.

35. Frequently Asked Questions

Q1. Can electronic evidence be challenged in a Mumbai criminal case? Yes — on multiple grounds including missing Section 63 BSA certificate, defective certificate, broken chain of custody, hash value mismatch, timestamp inaccuracy, device authenticity dispute, and content manipulation.

Q2. What is the Section 63 BSA certificate? A certificate required for the admissibility of electronic records as secondary evidence, signed by a person in a responsible official position in relation to the relevant device. Held mandatory by Arjun Panditrao Khotkar (2021).

Q3. What happens if the prosecution produces electronic evidence without a Section 63 BSA certificate? The defence should immediately object when the prosecution attempts to exhibit the document. Without the certificate, the electronic record is inadmissible under the Arjun Panditrao ruling.

Q4. What is hash value verification? A forensic technique generating a unique digital fingerprint of a file. If the hash value of the file produced in court differs from the hash value recorded at extraction, the file has been altered.

Q5. When should I raise an objection to electronic evidence? Immediately when the prosecution attempts to exhibit (formally produce) the document. Objecting after exhibition may waive the admissibility challenge.

Q6. Is Shafhi Mohammad still good law? No — it was expressly overruled by Arjun Panditrao Khotkar (2021). The certificate requirement is mandatory without exception.

Q7. How do I challenge WhatsApp evidence specifically? Check the Section 63 BSA certificate — it must be from the phone's owner/custodian, not a police officer. Challenge selective production; challenge whether screenshots constitute a "computer output."

Q8. How do I challenge CCTV evidence specifically? Challenge the timestamp (was the recording device clock accurately synchronised?). Challenge the chain of custody from camera to court. Apply for FSL examination of the recording system's clock accuracy.

Q9. Can call detail records be challenged? Yes — the certificate must be from an authorised officer of the telecom operator; tower location evidence based on CDRs can be challenged on coverage radius grounds.

Q10. What is the FSL examination application? An application to the court to direct forensic examination of an electronic record by the Forensic Science Laboratory — to verify authenticity, hash value, timestamp, or tampering.

Q11. What is the difference between an admissibility challenge and a weight challenge? An admissibility challenge argues the electronic record should not be admitted at all. A weight challenge accepts admission but argues the court should give the record little evidential value. Both strategies can be combined.

Q12. What law governs electronic evidence now in India? The Bharatiya Sakshya Adhiniyam (BSA) 2023 — effective from July 1, 2024. Section 63 BSA replaces Section 65B IEA. For cases before July 1, 2024, the IEA framework applies; for cases after, the BSA 2023 framework applies.

Conclusion

Electronic evidence is not automatically reliable merely because it is digital — and Indian law, through the Bharatiya Sakshya Adhiniyam 2023 and the Supreme Court's ruling in Arjun Panditrao Khotkar, provides a robust framework for challenging it. Seven distinct grounds exist for challenging electronic evidence, from the most powerful (missing Section 63 BSA certificate) to the most technical (hash value mismatch and timestamp inaccuracy).

The key is preparation and timing. Build the challenge matrix before the evidence stage begins. Raise admissibility objections the moment exhibition is attempted. File the FSL examination application early. Cross-examine the certifying witness on the specific defects. In cases where electronic evidence forms the backbone of the prosecution's case, a well-executed electronic evidence challenge can make the difference between conviction and acquittal.
