The leader of Tanzania’s opposition party, CHADEMA, Tundu Lissu, is expected to return to court on Monday, 10 August 2026, to continue his treason trial after it stalled for several months.

His case was adjourned in March this year after the prosecution appealed a High Court decision that rejected the government’s application to have one of the witnesses give additional evidence.

Tundu Lissu, who is representing himself in the case, objected to the government’s witness, police officer Amini Mahamba, from adding new evidence. The objection was accepted by the three-judge bench hearing the case.

Last week, Tanzania’s Court of Appeal dismissed the state’s review application, a decision that is final in the Tanzanian judicial system, paving the way for the case to resume on August 10.

Lissu and the lawyers assisting him are expected to ask the High Court to dismiss the case against their client because the High Court rejected crucial evidence relied on by the Republic; therefore, Lissu has no case to answer.

On Monday, it will be known whether the Republic will decide to proceed with the case. The case has been criticized by domestic and international stakeholders who claim it was politically motivated.

Tundu Lissu was arrested in April 2025, a few months before the country held its October general election, which was marred by violence in which hundreds of citizens were killed. The politician has been in detention since then.
