4. ADMISSIBILITY OF DIGITAL EVIDENCE IN LAWS
4.1 Pre- requisite for admissibility of Digital Evidence
i. Submitting Digital data as evidence
To ensure that digital evidence is admissible in court, certain legal and technical prerequisites must be
satisfied.32. Legally, courts scrutinize the authorization for searches and seizures of digital information,
as well as the relevance, authenticity, integrity, and reliability of the evidence. Regarding the technical
aspect, courts evaluate digital forensics procedures, tools, laboratories, forensic reports, and the
qualifications of forensic analysts and expert witnesses. Digital evidence gathered by unauthorized
search and seizure
could always be challenged as a fruit of a poisonous tree and may be inadmissible
in a court of law. Such evidence violates legal standards established to safeguard privacy and ensure
fairness in criminal proceedings. Admitting evidence obtained unlawfully undermines public trust in
judicial processes, promotes abuse of authority, and establishes a perilous precedent for future
investigations. It is therefore crucial to uphold the rule of law and protect individual rights. This
approach is necessary to maintain the integrity of the legal system and to protect individual's
constitutional rights against unreasonable searches.
ii. Digital Evidence Assessment
In this phase, courts ascertain whether the proper legal authorization was obtained to search for and
seize information and communication technology (ICT) and associated data. This authorization
typically comes in the form of a search warrant, court order, or subpoena, and varies depending on
national laws and the specifics of the case. While search warrants are commonly used to seize ICT,
the requirements for legal orders differ among jurisdictions based on factors such as the circumstances
of the case and the qualifications of those conducting the search.
Additionally, the forensic relevance of the digital evidence is evaluated during this phase. This involves
determining whether the evidence establishes or disproves connections between the perpetrator and
the victim, crime scene, or digital devices. It also involves assessing whether the evidence supports or
