Human rights campaigners expect Indonesia's Supreme Court to make a decision in Lindsay Sandiford's case "within 96 days" from her lodging an appeal today.
Zoe Bedford, from legal charity Reprieve, said:
Lindsay remains extremely grateful to the generosity of the public in raising the funds to allow her to file this appeal.
We are hopeful that the Supreme Court will take into consideration the compelling mitigating evidence in Lindsay's case and award her a sentence that is proportionate both to the offence and to her role in it.
In particular, it is hoped that the judges will give due consideration to Lindsay's cooperation with the authorities which led to the arrest and prosecution of more senior syndicate members, and take into account the need to encourage others to cooperate in the future.
