2026: International criticism of trial and detention

Protagonist is the victim

Protagonist is the victim — these proceedings are not counted in their formal charges or convictions.

Amnesty described the proceedings as unfair, citing restrictions on defence access and detention conditions. The UK government referred to the UN Working Group’s arbitrary-detention opinion and urged respect for due process. These statements concern Tanzanian authorities, not a second conviction of Lissu.

State of the evidence
Public statements by Amnesty and the UK government.
Legal status — source text
Public international criticism, without a new judgment on those allegations.
Attribution
No additional wrongdoing by Lissu; criticism concerns his treatment.
