Cybercrime and Jurisdiction in Tanzania: A Central Challenge to Law Enforcement Authorities

The borderless nature of cyberspace poses significant challenges to the exercise of criminal jurisdiction by states. Before the advancement of technology principle governing criminal jurisdiction was basically tied to the geographical area. In Tanzania, the prosecution of cybercrime raises complex questions concerning prescriptive, adjudicative, and enforcement jurisdiction, particularly where offences are committed wholly or partly outside national territory. This article critically examines the jurisdictional framework governing cybercrime prosecution in Tanzania, with specific reference to the Cybercrimes Act, [Cap 443, R.E 2023]. It analyses the extent to which Tanzanian courts and law enforcement authorities are legally empowered to investigate, prosecute, and adjudicate cybercrime offences with cross-border elements. Drawing on comparative jurisprudence and relevant international legal instruments, this article evaluates the adequacy of Tanzania’s statutory framework in addressing jurisdictional challenges in cyberspace. It argues that while Tanzanian law provides a foundational basis for asserting jurisdiction over cybercrime, doctrinal ambiguities, enforcement limitations, and dependence on international cooperation significantly constrain its effectiveness. As stated, cybercrimes are committed over the internet, which may involve various persons from different countries. The issue of jurisdiction, as to whether law enforcement officers have the power to arrest and prosecute for an offence committed out of their jurisdiction, has to be determined first.
