Tanzania has charged John Pambalu, a senior official of the main opposition party Chadema, with treason — an offence that carries the death penalty — accusing him of trying to obstruct the October 2025 general election through protests. He is the second top Chadema figure to face the charge, after party chairman Tundu Lissu, whose verdict is due on November 6, 2026.
What happened
Pambalu, Chadema's director for organisation, training and elections and a member of its national council, was arrested in Arusha in northern Tanzania and taken to Dar es Salaam, the party's legal and human rights director Gaston Garubindi said. He was charged at the Kisutu Resident Magistrate's Court, and the charge sheet was made public on Wednesday, October 21.
According to the charge sheet, between September 1 and October 29, 2025 Pambalu formed an intention to "persuade the public" to obstruct the general election, and showed that intention by "conducting endless protests" across the country to intimidate the executive. The case is brought under Section 39(2)(d) of the Penal Code, which covers intent to intimidate the executive, legislature or judiciary shown through a publication or an overt act. Conviction carries a mandatory death sentence, although Tanzania has not carried out an execution in decades.
| Case | Accused | Court | Status |
|---|---|---|---|
| Treason (2025 election protests) | John Pambalu, Chadema director of organisation | Kisutu Resident Magistrate's Court, Dar es Salaam | Charged; next hearing not yet announced |
| Treason (April 2025 speech) | Tundu Lissu, Chadema chairman | High Court, three-judge panel | Judgment due November 6, 2026 |
Background
Chadema was barred from the October 29, 2025 general election after refusing to sign an electoral code of conduct, with Lissu demanding reforms first. President Samia Suluhu Hassan was declared the winner with 98% of the vote, a result the opposition rejected.
Protests on and after election day were met by a heavy security response. The opposition and rights groups say about 2,000 people were killed by police and security forces. An inquiry set up by the president put the death toll at 518, concluded that the unrest was planned and coordinated, and did not name those responsible for the killings — findings Chadema and ACT-Wazalendo rejected as a cover-up.
Lissu was arrested in April 2025 and charged with treason over remarks at a party meeting that prosecutors say were meant to incite the public against the government. His trial, which he calls a "political case", has now closed, with the prosecution asking for conviction and his defence arguing the evidence is insufficient. Chadema says 51 of its members were also arrested and charged after the July 7 "Saba Saba" demonstrations this year, and 23 people were charged with terrorism in Mwanza.
Hassan came to power in 2021 after the death of President John Magufuli and was at first praised for easing curbs on the opposition and the media. Critics now say her government has returned to Magufuli-era repression.
Reactions
Chadema denies that Pambalu's protests were intended to intimidate the government and says the case is part of a wider crackdown on its leadership. Deputy chairman John Heche, speaking at a public meeting in Arusha, said he expected a similar case to be brought against him but would not flee the country, adding that the party would "fight to the end".
Home Affairs Minister Patrobass Katambi has rejected claims that arrests target any party, saying authorities are dealing with criminal conduct and that no one is above the law. Rights groups and observers have described the treason cases as part of a pattern of pressure on critics.
Why it matters
Treason charges against two of Chadema's most senior figures leave Tanzania's largest opposition party facing the possible loss of its top leadership. The cases are being closely watched by African and Western governments, donors and investors as a test of the rule of law in one of East Africa's largest economies, a major tourism destination and a key transit route for landlocked neighbours. Pakistan and Tanzania maintain trade ties, and the region's stability matters to the sizeable South Asian community living in Dar es Salaam.
What happens next
The High Court will deliver judgment in Lissu's case on November 6, 2026. A date for Pambalu's next appearance at Kisutu court has not been announced. The first anniversary of the October 29 election violence falls next week, and a regional commission appointed by the president has 150 days to identify people for possible criminal accountability over the unrest.
