Former Kenyan Chief Justice David Maraga arrived in Dar es Salaam on May 19, 2025, to observe the high-profile treason trial of Tanzanian opposition leader Tundu Lissu. Maraga announced his arrival on social media, stating he was “headed to court for the Tundu Lissu Court Case.” His presence underscores the growing regional interest in the trial, which has attracted international scrutiny.

The trial, taking place at Kisutu Magistrates’ Court, has been marked by controversy and political tension. Lissu, leader of the CHADEMA party, faces charges of treason and publishing false information related to statements made on April 3, 2025, in which he allegedly called for the disruption of the upcoming October elections. He has denied the charges, asserting that his remarks were expressions of democratic dissent, not criminal incitement.

The case has been delayed multiple times, with the defense accusing the prosecution of dragging its feet. At a previous hearing, Lissu refused to participate in virtual proceedings, insisting on a physical court appearance. On May 19, the court ruled that Lissu must be brought to court in person for the preliminary hearing, citing his constitutional right to a fair hearing. The prosecution has been ordered to expedite investigations and provide an update on the case’s progress.

Maraga’s arrival coincides with a wave of deportations and detentions of Kenyan activists and legal observers attempting to attend the trial. Former Chief Justice Willy Mutunga, along with human rights defenders Hanifa Adan and Hussein Khalid, were detained at Julius Nyerere International Airport in Dar es Salaam. Additionally, former Minister Martha Karua, lawyer Gloria Kimani, and activist Lynn Ngugi were deported back to Kenya. Kenya’s Foreign Ministry has called for the immediate release of these individuals, citing violations of East African Community norms.

The Tanzanian government’s actions have drawn criticism from regional and international human rights organizations, which view the treatment of Lissu and the deportation of observers as part of a broader crackdown on political dissent ahead of the 2025 general elections. The trial continues to be a focal point for discussions on democratic freedoms and the rule of law in the region.
