An Indonesian court has thrown out defence arguments that the case against cleric Abu Bakar Ba'asyir should be dismissed.
Ba'asyir stands accused of being the spiritual leader of militant Islamic network Jemaah Islamiah (JI).
But the cleric's lawyers had argued the charges against him were flawed.
The South Jakarta court would start hearing witnesses in the case next week, said chief judge Sudarto. The trial could take several months.
"We reject the objections made by the lawyers," said Sudarto.
"We, the judges, rule that the trial should continue next week with the prosecutors presenting their witnesses."
During the trial, the prosecution will argue that, in the influential position as JI's alleged spiritual leader, he encouraged and facilitated those under him to carry out acts of terrorism.
These included the Bali attacks and a 2003 suicide bombing of the JW Marriott hotel in Jakarta.
Some of the charges he faces could, if proven, carry the death penalty.
But Ba'asyir has said the charges against him are fabricated, and insists the trial is an American-led conspiracy.
He was acquitted of treason charges last year, after judges ruled that there was not enough evidence to link him to JI.
But prosecutors now say they have further evidence to back up their case.
