Suu Kyi's extended detention was condemned outside Burma
The Supreme Court in Burma says it may allow the pro-democracy leader, Aung San Suu Kyi, to appeal against her extended detention.
The court said it would hear the case on December 21.
Ms Suu Kyi was sentenced to a further 18 months under house arrest earlier this year.
She was found guilty in August of violating her house arrest by harbouring an American well-wisher who swam to her lakeside home.
The court in Rangoon posted the announcement on its notice board. This follows the rejection of an initial appeal in October.
"The Supreme Court decided to hear Aung San Suu Kyi's request. Lawyers have to present arguments before the court in December," a Burmese official told AFP.
Serving the additional time of her sentence would keep Ms Suu Kyi in detention during Burma's first elections in two decades, scheduled for next year.
Burma's military rulers have kept the Nobel Peace Prize winner and leader of the opposition National League for Democracy party (NLD) in some form of detention for more than 14 of the last 20 years.
