2. Key Developments in Digital Evidence

Early Court Use

From the late 1970s and early 1980s, courts began admitting computer-generated records as evidence.
These early cases focused on questions of authenticity and reliability.
One of the earliest widely cited cases is R v. Wood (England, 1982), which addressed the admissibility of computer records. Similar questions were being considered in courts across Europe and North America around the same period, as computers entered workplaces and public administration.
While this case arose in a national context, it reflects a broader European shift toward recognising digital records as evidential material, provided their reliability could be demonstrated.

Expansion of the Internet

As internet use expanded in the 1990s, digital evidence moved beyond isolated computer systems to include:

  • Emails and online communications
  • Early web activity records
  • Network and server logs

This period marked a transition from digital evidence being relatively rare to becoming a routine part of investigations.
The rise of personal computers and later mobile phones significantly increased both the volume and variety of digital evidence.

Cyber-Dependent and Cyber-Enabled Crime

As digital technologies became embedded in daily life, crime also increasingly involved digital systems. Cybercrime includes offences that:

  • Target digital systems directly, such as hacking or malware
  • Use digital technologies to enable traditional crimes, such as fraud or exploitation

Digital evidence is central to investigating these crimes, often forming the primary source of information.
Europol reports consistently show year-on-year growth in cyber-enabled crime across Europe, increasing reliance on digital evidence in both investigation and prosecution.
