5. INTERNATIONAL PRACTICES ON RECOGNITION AND
REALIZATION OF DIGITAL EVIDENCE
Digital evidence plays a crucial role in criminal investigations and prosecutions across various Asian
countries, as highlighted in a research report commissioned by the International Criminal Police
Organisation and conducted by The University of Hong Kong.35
i.
Bangladesh: In Bangladesh, case law recognizes video and audio recorded evidence as
falling within the definition of “document” under the Evidence Act (1872). The Speedy
Trial Tribunal Act expressly admits electronically recorded evidence, but the court cannot
convict the accused on this evidence alone. The Information and Communication
Technology Act (2006) (ICTAB) and the Digital Security Act (2018) (DSAB) were enacted
to address cybercrime in Bangladesh. The ICTAB clarifies that a statement recorded
digitally in electronic form qualifies as a written statement under the Evidence Act. The
DSAB put in place procedures to regulate the forensic investigation of digital evidence.
The Cyber Tribunal, created by the ICTAB, can admit “forensic evidence” obtained or
collected under the DSAB.
ii.
Bhutan: The definition of “evidence” in Bhutan’s Evidence Act (2005) includes electronic
documents and records. The court may decline to admit an electronic document if a
genuine question is raised as to the security or integrity of the electronic document system
used to record or store the document. Though hearsay evidence is inadmissible, the court
has wide discretionary powers to admit hearsay. The Information, Communications and
Media Act (2018) confers legal recognition on data messages and electronic documents.
iii.
Brunei: In Brunei’s Evidence Act (2014 edition) the definition of “document” includes
any matter recorded, stored, processed, retrieved, or produced by a computer. Though
hearsay evidence is inadmissible, both the Evidence Act and the Computer Misuse Act
(2007 edition) allow for the admission of statements produced by a computer to prove the
truth of the contents, under certain conditions. In assessing the weight to be given to a
document produced by a computer, the court should consider all of the circumstances,
including whether the information was supplied to the computer contemporaneously with
