Abstract
The rapid expansion of digital networks and the borderless nature of cyber activity have intensified the need for robust legal mechanisms to combat cross-border cybercrime. In South Africa, the Cybercrimes Act 19 of 2020 represents a landmark legislative development, codifying a broad range of cyber offences, including unlawful access, interception, data interference, cyber fraud, forgery, and malicious communications, while also addressing jurisdictional complexities inherent in transnational offences.1This paper critically examines how the Act can be strategically exploited to enable the effective prosecution of cross-border cybercrimes, particularly through its extraterritorial jurisdiction provisions under section 24 and its international cooperation measures in Chapter 5.
The study explores the Act’s jurisdictional bases, including the nationality principle, territorial nexus, and effects doctrine, and highlights the procedural requirement for National Director of Public Prosecutions (NDPP) authorisation in cases involving offences committed wholly or partly outside South Africa.2It also analyses mechanisms for mutual legal assistance under section 48, situating them within the broader framework of regional and global instruments such as the Budapest Convention on Cybercrime (2001), to which South Africa is a signatory but not yet a ratifying party.3
The research identifies key strengths of the Act, including its alignment with international cybercrime norms, its broad definitional scope, and its potential to overcome traditional sovereignty barriers via targeted cooperation agreements.4 However, it also underscores limitations: delays in mutual legal assistance processes, the absence of explicit provision for parallel civil remedies, and challenges in securing evidence stored in foreign jurisdictions. Comparative insights from other jurisdictions suggest that ratification of the Budapest Convention, enhanced resourcing for law enforcement cyber units, and legislative reform to support civil claims could significantly bolster South Africa’s cross-border enforcement capacity.5
The findings conclude that while the Cybercrimes Act provides a strong legal foundation, its optimal exploitation for cross-border prosecution will require a combination of legal refinement, institutional capacity-building, and deepened international collaboration.6
These obstacles often result in delayed investigations, compromised evidence integrity, and, ultimately, reduced prosecutorial success rates. The question, therefore, is not merely whether the Cybercrimes Act enables prosecution of such offences, but...
