Brazil's Supreme Court has authorised the enforcement of former president Jair Bolsonaro's 27-year prison term for attempting to overturn the country's constitutional order, with Justice Alexandre de Moraes ruling on November 25 that Bolsonaro must remain at Federal Police headquarters in Brasília, according to court documents.

Bolsonaro has been detained at the Federal Police facility since November 22, when he was taken into custody after allegedly tampering with the electronic monitoring device he was required to wear during house arrest, which the court treated as evidence of flight risk.

In his ruling, Moraes ordered "official medical examinations for the commencement of the sentence, including the clinical observations essential for adequate prison treatment," according to the court order.

The court issued the enforcement order after Bolsonaro's legal team declined to lodge further appeals, a right they had until November 24. Earlier that day, the Supreme Court's First Chamber confirmed the completion of the criminal case and declared the conviction final.

Bolsonaro had been serving house arrest since August for breaching precautionary conditions set during the proceedings. The former president's detention followed a pattern of escalating restrictions, beginning with social media bans, progressing to house arrest, and culminating in preventive detention after an attempted breach of his electronic monitoring equipment.

The far-right leader had pleaded with Congress to vote on an amnesty for those convicted of coup attempts, his son said.

Senator Flávio Bolsonaro told reporters his father had asked him "to urge the presidents of the Chamber of Deputies and the Senate to put the amnesty bill to a vote. It's a direct request from him," referring to Chamber president Hugo Motta and Senate president Davi Alcolumbre.

Family members and legislators from the Liberal Party said their priority is now securing a vote on the amnesty proposal, which was submitted two months ago but has not been scheduled.

Flávio Bolsonaro said his father requires "dignified treatment" and "special nutrition" due to past intestinal surgeries, adding that Bolsonaro had experienced hiccups "that can cause a lung infection that can be fatal."

Meanwhile, authorities have taken measures to minimise public spectacle surrounding the controversial former president's detention. According to Estadao, federal Police agents did not release images of Bolsonaro being taken into custody, and film on the door where he had been photographed was replaced.

The First Chamber's decision also finalised rulings against two other defendants: deputy Alexandre Ramagem, sentenced to 16 years and currently in the United States, and former Justice Minister Anderson Torres, sentenced to 24 years.

Among other military officers convicted by the Supreme Court are General Paulo Sérgio Nogueira, who commanded the Army and served as Defence Minister, and Augusto Heleno, who headed the Institutional Security Office. Both served in Bolsonaro's administration and will serve their sentences in a military unit.

While Bolsonaro could be transferred to Papuda Penitentiary depending on developments, a return to house arrest is being ruled out since that location was the scene of the attempted breach of security equipment, according to court officials.
