Tundu Lissu Convicted of Incitement, Acquitted of Treason in Tanzania

What changed

Tanzania’s main opposition leader, Tundu Lissu, has been convicted of incitement but acquitted of treason by a three-judge High Court panel in Dar es Salaam. Lissu, who has been detained since April 2025 over remarks made while campaigning for electoral reforms before the disputed 2025 election, has leave to appeal to the Court of Appeal.

Why it matters

The ruling removes the most severe charge from the case, but it still leaves a criminal conviction against the leader of Chadema. The court has not yet announced a sentence, and it is not clear whether Lissu will appeal.

That distinction matters because treason can carry the death penalty in Tanzania. Incitement is less severe, but the conviction still turns a campaign for electoral reform into a legal liability.

Lissu’s demands included independently appointed electoral commissioners, freer campaigning, less politically controlled election administration and the right to challenge presidential results in court. He argued that prosecutors stripped his remarks of their context and treated political advocacy as a crime.

The timing gives the judgment a larger political weight. President Samia Suluhu Hassan won the October 2025 election with 98% of the vote after Lissu and another main challenger were excluded. Post-election violence later killed at least 500 people, according to an official inquiry. The government has defended its conduct, while opposition groups have called for an independent investigation.

The immediate question is whether the conviction narrows Tanzania’s already contested space for political dissent. The next test lies with the Court of Appeal, and with whether the government changes any of the electoral practices Lissu’s campaign challenged.
