Burmese pro-democracy leader Aung San Suu Kyi has lodged an appeal with the military-ruled country's highest court against her extended house arrest.
The Nobel laureate was ordered to spend another 18 months in detention in August after a court convicted her over an incident in which a US man swam to her house.
An initial appeal was rejected in October.
'We submitted the appeal petition to the supreme court. Now we must wait to find out whether the court will agree to hear the case,' Kyi Win, the head of Ms Suu Kyi's legal team, said outside the court.
'We hope for the best,' Kyi Win said.
The fresh appeal came as Ms Suu Kyi's case was set to dominate an expected meeting between US President Barack Obama and the Burmese prime minister in Singapore at a regional forum on Sunday.
US Secretary of State Hillary Clinton yesterday called on Burma, officially known as Myanmar, to free 64-year-old Ms Suu Kyi, who has been in jail or under house arrest for 14 of the last 20 years.
The ruling junta refused to recognise the landslide victory of her National League for Democracy in elections in 1990.
The extension of her house arrest effectively keeps her off the stage for new multi-party elections promised by the ruling generals some time in 2010.
Burma's prime minister, Thein Sein, is expected to join Sunday's meeting at the Asia-Pacific Economic Cooperation summit.
The encounter would be the first meeting between a US president and a Burmese leader in 43 years.
