Ugandan opposition politician Dr. Kizza Besigye filed a petition Tuesday seeking to terminate his detention and treason trial in the High Court Criminal Division.

The legal move represents a direct challenge to the state's authority to hold one of the country's most prominent critics of the government. A successful petition could undermine the current prosecution's legal standing and signal a shift in the judicial handling of political dissidents.

Besigye and co-accused Hajji Obeid Lutale filed the application June 9, 2026 [1], [2]. The two applicants [3] are asking the court to halt criminal proceedings that Besigye said are politically motivated.

In the filing, Besigye said the state has committed gross violations of his constitutional rights [4], [5]. The petition seeks the immediate termination of the treason case and an end to what he characterized as unlawful detention [4], [5].

Separate reports indicate the legal action extends beyond the treason trial. Besigye has also filed an application regarding threats made by Muhoozi to hang him on Heroes Day [4].

The proceedings take place in Kampala, where the High Court Criminal Division oversees high-profile state cases [4]. The court must now determine if the constitutional breaches alleged by the defense are sufficient to void the ongoing criminal proceedings.

Because the case involves allegations of treason, the outcome will likely be scrutinized by international observers monitoring the state of human rights and the rule of law in Uganda.

Besigye alleges gross violations of his constitutional rights

This legal challenge tests the independence of the Ugandan judiciary in balancing national security claims—such as treason—against the constitutional rights of political opponents. By targeting the legality of the detention itself, Besigye is attempting to shift the narrative from a criminal trial to a human rights violation case, which could increase international pressure on the Ugandan government.
