A Bolivian judge has ordered former president Luis Arce to stay in pretrial detention, rejecting his defence’s bid for house arrest. Judge Román Castro ruled at a virtual hearing on Tuesday 29 September 2026, EFE and Unitel reported.
Arce, who governed from 2020 to 2025, has been held since December 2025 in the Fondo Indígena corruption case. He is currently in a La Paz hospital and must return to San Pedro prison once discharged.
What the Judge Decided
The defence asked the court to lift the pretrial detention so Arce could await trial at home. Castro refused, saying the defence had not backed its health arguments with suitable documents, according to EFE.
He did order the prison service to use every means inside San Pedro whenever Arce needs a doctor. If that care falls short, the judge must be told at once so Arce can be taken to hospital.
A specialist will decide when Arce is fit for discharge, and the court must be told before he returns to prison. His defence said it would appeal and asked the judge to clarify the ruling.
The Case Against Him
The Fondo Indígena was a state fund set up under Evo Morales (2006–2019) to finance projects for indigenous and peasant communities. Prosecutors allege Arce, then economy minister, authorised transfers of its money to personal accounts of peasant leaders.
The projects that money was meant to fund failed, the prosecution says. Arce denies wrongdoing and calls his detention political persecution, eju.tv reported.
EFE also reported a separate investigation into alleged laundering of illicit gains involving Arce and his eldest son, Marcelo. The son was moved to house arrest last week after six months in prison, Infobae reported.
Health, Hospital and Competing Claims
Arce left San Pedro on 16 September for the Arco Iris hospital in La Paz under an earlier order by another judge. The Rio Times covered that ruling in Bolivia Court Orders Luis Arce Moved From Prison to Cancer Hospital.
Accounts of his condition differ. EFE says he is being treated for cancer, while Infobae says doctors are reviewing a cancer he had years ago.
At the hearing Arce said he was “no coward” who would flee the country under house arrest. “I will face all the charges here,” he told the judge, according to EFE.
Eduardo León, the lawyer who brought the original Fondo Indígena complaint, argued the opposite on 28 September. He alleged a “political deal” to win Arce house arrest and said four diplomatic passports were never returned.
Neither of León’s claims has been independently confirmed. Arce’s defence has not publicly answered them.
Why the Ruling Matters
Bolivia has a long record of prosecuting former leaders after power changes hands. Jeanine Áñez, interim president after the 2019 crisis, spent years in detention before her release.
Each political camp tends to call its rivals’ cases justice and its own cases persecution. That makes the handling of Arce a test of whether the courts can be seen as even-handed.
The signal from this ruling is mixed rather than one-sided. It keeps the most prominent case since the change of government moving, while the medical safeguards weigh the detainee’s rights.
President Rodrigo Paz, who took office in November 2025, faces a fuel shortage and a strained economy alongside these cases. For background, see Bolivia Explained: The Paz Government, the Fuel Crisis and What to Watch.
What Is Not Yet Known
It is not known when the appeal will be heard or which court will hear it. There is also no date for Arce’s discharge from hospital.
Prosecutors have not published a timetable for taking the Fondo Indígena case to trial. The whereabouts of the passports León mentioned have not been confirmed by any official body.
