More than three hundred days after Tundu Lissu was arrested and charged with treason, the case against Tanzania’s most prominent opposition leader is not moving toward a verdict. It is moving in circles. On July 3, a three-judge Court of Appeal bench in Dar es Salaam heard yet another procedural application — this time the State’s bid to review a High Court ruling that barred prosecutors from introducing fresh evidence. Lissu, for his part, is now seeking compensation over the delay. A treason trial that was supposed to demonstrate the strength of the State’s case is instead demonstrating its weakness, and the whole spectacle has become a study in how authoritarian legalism works: the punishment is the process.
The charge itself is revealing. Lissu, the CHADEMA chairman who survived being shot sixteen times in 2017, faces a single count of treason under the Penal Code over statements he allegedly made suggesting an intention to obstruct the October 2025 general election. That election, held under President Samia Suluhu Hassan, was preceded by CHADEMA’s refusal to sign the electoral code of conduct and followed by what observers described as an unprecedented wave of abductions, arrests, and killings. The African Union’s own observer mission called for urgent constitutional reforms. An American Bar Association report concluded that Lissu’s trial is politically motivated. In that context, a treason charge resting on campaign rhetoric looks less like law enforcement than like the removal of an opponent by other means.
What makes the case a slow-motion embarrassment for the government is that it keeps losing the procedural fights it picked. Lissu’s defence has repeatedly outmanoeuvred the prosecution — blocking the State’s attempt to reopen evidence, filing preliminary objections that stall the appeal, and forcing the Republic to litigate technicalities rather than substance. In February a judge sustained a defence objection; in July Lissu challenged the very reviewability of the ruling the State was trying to appeal. Each round buys time, but time cuts both ways. The longer Lissu sits in custody without a verdict, the clearer it becomes that the objective was never a conviction. It was his removal from the political stage.
This is the quiet cruelty of the strategy. A defendant held for over three hundred days on a charge that cannot be brought to trial is neutralised just as effectively as one who is convicted, and with less political cost to the government than an outright guilty verdict that appellate courts or international opinion might overturn. The trial becomes the sentence. Lissu’s demand for compensation over the appeal delay is a sharp piece of legal jujitsu — it reframes the State’s foot-dragging as an actionable injury and forces the court to confront the fact that justice delayed here is very much justice denied by design.
For a Kenyan and East African readership, the Lissu case should not be filed under “Tanzania’s internal affairs.” It is a regional warning. Across East Africa, incumbents have been perfecting the art of using courts, electoral commissions, and public-order laws to manage opposition without the crude optics of banning it outright. Uganda held an election in January that returned Museveni to a seventh term amid internet shutdowns and repression. Tanzania ran an October poll hollowed out by the prosecution of the main opposition’s leader. The methods differ; the logic is identical. Democracy is not abolished — it is administered into irrelevance.
Tanzania under Samia was, briefly, a hopeful story. She came to power in 2021 promising a thaw after John Magufuli’s harsh rule, lifting a ban on opposition rallies and courting international investors. The Lissu prosecution is the clearest evidence that the thaw has refrozen. A government confident in its own legitimacy does not need to jail its most articulate critic on treason charges it cannot prove. The case is, in a sense, a confession: it reveals a ruling party that fears the contest more than it trusts the verdict of voters.
The East African Community, of which Tanzania is a founding member, will say nothing meaningful about any of this. The bloc has built its identity around trade, infrastructure, and market integration while treating the internal politics of member states as untouchable. That silence has a cost. A regional community that can harmonise tariffs but cannot utter a word when a member jails an opposition leader on political charges is a trading arrangement wearing the costume of a political union. The people of the region notice the difference even when their governments pretend not to.
What to watch: whether the Court of Appeal’s July ruling finally unblocks the case or sends it back into procedural limbo, and whether Lissu’s compensation claim gains traction as a novel form of pressure. Watch, too, whether Samia’s government calculates that continued detention is becoming more costly than release. The likeliest outcome, unfortunately, is more of the same — another postponement, another objection, another month in custody. That is not a failure of the system. In cases like this, it is the system working exactly as intended.
