How the TISS Act 2023 Laid the Legal Ground for Tanzania’s October 29 Massacres
Ujasusi East Africa Monitoring Team | 13 May 2026 | 0115 BST
The Tanzania Intelligence and Security Service (Amendment) Act 2023 did not itself order massacres. Laws do not pull triggers. What the Act did was construct, methodically and deliberately, the legal, institutional and operational architecture that made mass political repression easier to organise, harder to expose, and more difficult to investigate. By transferring superintendence of the intelligence service from a minister directly to the presidency, broadening the mandate to include threat neutralisation, formalising armed operational capacity, expanding inter-agency coordination and dramatically strengthening secrecy and immunity provisions, the 2023 amendments transformed Tanzania’s intelligence system into a more centralised and coercive regime-security apparatus, just 28 months before the October 29, 2025 election violence.

The massacres that followed were therefore not an intelligence failure, a security overreaction, or a localised police excess. They were the visible eruption of an invisible architecture that had already been legally consolidated.

🏛️ The 2023 Amendment: What the Law Actually Changed
To understand the role of the TISS Act 2023 in the October 29 massacres, it is necessary to examine what the law actually amended, not in general terms, but provision by provision.
The original TISS Act of 1996 placed the intelligence service under the control of a minister responsible for intelligence and security. That ministerial layer, however thin, represented a degree of administrative separation between the presidency and the intelligence apparatus. The minister could be questioned in parliament, could be changed without dissolving the intelligence structure, and provided at least a nominal accountability buffer.
The 2023 Amendment Bill explicitly removed all ministerial provisions and placed that mandate directly under the President. In a single legislative stroke, the buffer was eliminated. The Service now operates as a defence and security organ under the general superintendence of the President, a provision codified in Section 4(3) of the consolidated Act.
This was not a technical reclassification. It was a structural transformation. An intelligence service accountable to a minister is one type of institution. An intelligence service directly subordinated to the president, in a dominant-party system with weak parliamentary oversight, no independent judiciary capable of checking executive power, and an upcoming existential election, is categorically different.
The government’s own parliamentary presentation framed the change as aligning TISS with “the nature and operations of other intelligence agencies across the world.” The bill was not published on the parliament’s official website, with one official commenting that it was “not a public document.” The secrecy with which the amendments were advanced was itself instructive.
Opposition politician Zitto Kabwe accused the administration of attempting to force the amendments through parliament without public oversight, describing it as both unusual and improper. Tundu Lissu, then CHADEMA’s de facto presidential candidate and already a documented target of state intelligence operations, was more direct. Speaking at a rally in Katavi in May 2023, he warned that intelligence persecution of citizens, previously conducted under ministerial order, would now be conducted under direct presidential authority. Within two years, Lissu would be arrested on treason charges, tried before a Tanzanian court, and remain imprisoned throughout the October 2025 election.

The second consequential amendment concerned the operational character of the Service itself.
