Digital Evidence Standards And Admissibility In Afghan Courts
Digital Evidence Standards and Admissibility in Afghan Courts
1. Introduction
Digital evidence refers to any probative information stored or transmitted in digital form that a court can use to establish facts in a case. In Afghanistan, with increasing use of technology, courts face challenges regarding authentication, integrity, and admissibility of such evidence.
2. Legal Framework Governing Digital Evidence
Afghanistan’s laws do not yet have a comprehensive standalone statute on digital evidence, but the following provide the legal basis:
The Evidence Law (Qanoon-e-Shahadat)
The Penal Code (2017)
The Anti-Cybercrime Law (Drafted but not yet fully enacted)
The Evidence Law allows electronic records to be admissible if authenticity and integrity can be proven.
Courts rely on expert testimony and forensic analysis to establish the reliability of digital evidence.
3. Key Standards for Admissibility
Authenticity: The party submitting the evidence must prove that the digital data is genuine and unaltered.
Integrity: Ensuring that the evidence has not been tampered with.
Relevance: The evidence must be relevant to the facts in issue.
Chain of Custody: Documentation showing how evidence was collected, preserved, and handled.
Expert Testimony: Forensic experts often testify on the methods used to extract and verify digital data.
4. Case Law Examples

5. Challenges in Afghan Courts
