"The Supreme Court decided to hear Aung San Suu Kyi's request. Lawyers have to present arguments before the court on Dec 21," the official said on condition of anonymity.
64-year-old, Suu Kyi was ordered to spend another 18 months in detention in Aug 2009 after being convicted over an incident in which a US man swam to her lakeside house.
A lower court rejected an initial appeal in Oct 2009.
Nyan Win, a spokesman for Suu Kyi's National League for Democracy (NLD), confirmed that the top court had agreed to hear the appeal but said he had no further details.
