Digital Evidence And Cybercrime: Prosecutorial Challenges In Nepalese Criminal Courts
1. Introduction
In recent decades, Nepal has witnessed a surge in cybercrimes, ranging from online fraud and hacking to digital defamation and social media misuse. With this rise, digital evidence — such as emails, IP logs, social media data, CCTV footage, and mobile forensics — has become central to modern prosecutions.
However, the Nepalese criminal justice system faces many challenges in admitting, analyzing, and proving digital evidence due to limited technical expertise, absence of specialized digital forensic labs, and lack of clear procedural standards under the Evidence Act 2031 (1974) and Electronic Transactions Act 2063 (2008) (ETA).
2. Legal Framework in Nepal
a. Electronic Transactions Act (ETA) 2063 (2008)
This act is the primary cyber law in Nepal.
Section 47 criminalizes the publication of illegal materials in electronic form.
Section 48–52 cover hacking, unauthorized access, and data breaches.
Section 63 recognizes the admissibility of electronic evidence, stating that digital records can be used as evidence in court, provided their authenticity is proven.
b. Evidence Act 2031 (1974)
This Act provides general rules of evidence but lacks detailed provisions for digital forensics, making the chain of custody, authentication, and expert verification challenging.
3. Prosecutorial Challenges
Authenticity and Integrity — Verifying that data wasn’t tampered with.
Chain of Custody — Maintaining proper documentation of how digital evidence was collected, transferred, and analyzed.
Forensic Expertise — Lack of trained digital forensic experts in law enforcement.
Judicial Understanding — Courts sometimes struggle with technical aspects of digital data.
Jurisdictional Issues — Cybercrimes often cross borders, making evidence collection and extradition difficult.
Procedural Delays — Obtaining data from tech companies (e.g., Facebook, Google) can take months.
4. Major Nepalese Case Laws on Digital Evidence and Cybercrime
Case 1: Government of Nepal v. Sushil Sharma (2010)
Issue: Unauthorized access and hacking into a government email server.
Facts: Sushil Sharma, a computer student, was accused of accessing the Ministry of Education’s email servers and downloading confidential data.
Evidence: IP logs and server access records obtained from the government IT department.
Judgment:
The Kathmandu District Court admitted digital logs as valid evidence, marking one of the earliest recognitions of digital footprints under the ETA.
Sharma was convicted under Section 48 (unauthorized access) and Section 52 (data theft).
Significance: Set a precedent that server logs and digital records are admissible if verified by authorized technical experts.
Case 2: Government of Nepal v. Prakash Subedi (2014)
Issue: Online defamation through Facebook posts.
Facts: The accused had posted defamatory statements against a business rival on Facebook.
Evidence: Screenshots and Facebook message logs presented by the complainant.
Challenges: Defense argued screenshots could be edited and thus were unreliable.
Court Decision:
The Kathmandu District Court accepted screenshots only after Facebook verified the posts via official correspondence.
Conviction was made under Section 47 of ETA 2063 for publishing defamatory content online.
Significance: Established that digital evidence must be corroborated by platform verification to ensure authenticity.
Case 3: Government of Nepal v. Rajendra Bhandari (2017)
Issue: Online banking fraud using stolen ATM credentials.
Facts: The accused hacked into online banking systems and transferred funds to multiple accounts.
Evidence: Bank transaction logs, IP addresses, and CCTV footage from ATMs.
Challenge: Linking the digital IP address to the physical suspect.
Court’s Reasoning:
The Nepal Rastra Bank’s digital forensic unit verified that the same IP address was used in multiple fraudulent transactions.
CCTV footage provided supporting evidence linking Bhandari to the ATM withdrawals.
Outcome: Convicted under Sections 48 and 50 of ETA 2063.
Significance: The case showed that corroborative evidence (digital + physical) strengthens digital evidence reliability.
Case 4: Government of Nepal v. Anjana Gurung (2020)
Issue: Cyber harassment and online threats.
Facts: The accused repeatedly sent threatening and obscene messages to the victim via social media.
Evidence: Messenger chat logs, screenshots, and mobile forensic reports.
Defense: Claimed the messages were fabricated and her account was hacked.
Court Decision:
The Cyber Bureau of Nepal Police presented forensic reports verifying account ownership and message timestamps.
The Lalitpur District Court convicted the accused under Section 47 of ETA.
Significance: Recognized the importance of digital forensics in verifying the origin of electronic messages and account ownership.
Case 5: Government of Nepal v. Hari Prasad Chaudhary (2022)
Issue: Data breach and illegal sale of citizens’ personal data.
Facts: The accused, an IT officer, leaked personal data from a government database and sold it to a private company.
Evidence: USB drives, email correspondence, and forensic analysis of office computers.
Challenges: Defense claimed evidence was seized without a warrant.
Court Ruling:
The Patan High Court held that while search warrants are generally required, urgent data preservation justifies limited warrantless seizure in cybercrime cases.
Chaudhary was found guilty under Sections 48, 52, and 63 of ETA.
Significance: This case clarified procedural norms for digital evidence collection and privacy safeguards during investigation.
5. Observations and Analysis
| Issue | Observation | Judicial Trend |
|---|---|---|
| Admissibility | Courts accept digital evidence if verified by experts | Increasing acceptance post-2010 |
| Expert Testimony | Police and Nepal Telecom experts often testify | Still inconsistent |
| Chain of Custody | Not uniformly documented | Needs procedural guidelines |
| Training | Limited among prosecutors and judges | Judicial Academy now offering training |
| Legislation | ETA provides base but lacks detail | Need for Digital Evidence Act or amendment to Evidence Act |
6. Recommendations
Amend the Evidence Act 2031 to explicitly recognize electronic evidence rules (similar to India’s Section 65B of the Evidence Act).
Establish digital forensic labs in all provinces.
Training for prosecutors, judges, and police on cyber forensics.
International cooperation with tech companies for faster data retrieval.
Clear procedural rules for seizure, preservation, and certification of digital evidence.
7. Conclusion
Digital evidence has become crucial in Nepalese criminal justice, especially in cybercrime cases. While courts are gradually embracing technological realities, prosecutorial challenges remain — particularly regarding authenticity, chain of custody, and procedural clarity. The discussed cases show that Nepal’s judiciary is evolving but still needs a stronger legal and institutional framework to ensure digital justice in the cyber age.
