Cross-Border Cybercrime Jurisdiction and Digital Evidence Admissibility: A Comparative Legal Framework

Abstract

Transnational cybercrime has become one of the most difficult problems to modern legal frameworks thanks to the permeability 
of online space, globalization of online processes, and the rising level of sophistication of cybercriminal activities. Ransomware 
attacks, financial fraud, data breaches, identity theft and cyber espionage are also crimes in which various jurisdictions are 
often involved, posing a legal ambiguity on the powers of states to investigate, prosecute and sentence cyber-related crimes. 
Enforcement of cybercrime is also challenged by the presence of conflicting laws and jurisdictional claims across countries, 
localization of data needed, privacy laws, and restriction in the international systems of cooperation. Digital evidence has now 
become an essential part of cybercrime cases and trials, the key factor in proving criminal intent, the identity of the offenders, and 
the court hearings. Nonetheless, cross-border cases often fail in using digital evidence due to disparities in diverse jurisdictions in 
evidentiary standards, authentication protocols, chain-of-custody measures, and admissibility regulations. The paper incorporates 
a comparative law approach to investigate and analyze the jurisdiction of cybercrime and admissibility of digital evidence under 
the laws of major jurisdictions, such as the United States, the European Union, the United Kingdom, India, and Australia, as 
well as analyzing the significance of international documents like the Budapest Convention, Mutual Legal Assistance Treaties 
(MLATs), the European Investigation Order (EIO), and the U.S. CLOUD Act. As detected in the analysis, some of the recurrent 
issues are the jurisdictional overlap, procedural disparity, privacy safeguards, and delays in obtaining evidence, all of which lower 
the effectiveness of the global combating of cybercrimes. In accordance with these results, the study suggests a harmonized 
comparative legal framework, which would combine uniform jurisdiction as well as unified digital evidence admissibility grounds, 
greater judicial control, and simplified mechanisms of cross-border cooperation. The suggested framework is expected to enhance 
the legal certainty, provide better procedural protection, ensure the access to digital evidence in a timely manner and encourage 
a more international cooperation in fighting cybercrime. The research finds that significant harmonization of jurisdictional and 
evidentiary regulations is needed to tackle the dynamic character of cyber threats and to provide an efficient, rights-based, and 
internationally-coordinated response to cross-border cybercrime.
