Indonesia's Supreme Court has rejected a final appeal from the radical cleric linked to the Bali bombings, upholding his original 30-month sentence.
Indonesia sentenced Ba'asyir to 30 months in prison
Abu Bakar Ba'asyir was found guilty in March of conspiracy over the 2002 attacks, in which 202 people died.
But he was cleared of more serious anti-terrorism charges relating to an attack on Jakarta's Marriott hotel.
A spokesman for the court said Ba'asyir's appeal had been rejected during a session on Wednesday.
A lawyer for Ba'asyir told Agence France Presse that he had received a "verbal confirmation" of the ruling, though no formal letter had yet arrived.
Muhammad Assegaf said Ba'asyir considered the Supreme Court's ruling an "act of injustice".
In May, the Jakarta High Court upheld the initial ruling and Ba'asyir was forced to take his appeal to the Supreme Court.
Ba'asyir was handed down a 30-month sentence in May for having given his approval for the Bali attacks.
The cleric was convicted over the Bali bombings under ordinary criminal legislation, rather than the harsher anti-terror laws, which were only brought in after the 2002 attacks.
Police arrested him a week after the bombings and he was put on trial the next year but the charges linked to the Bali bombings were thrown out.
In April 2004, police rearrested him after he completed a jail sentence for immigration violations, citing new evidence linking him to Jemaah Islamiyah (JI).
The US has alleged JI has ties to Osama Bin Laden's al-Qaeda network.
