Myanmar's main opposition party decided Friday to sue the military-run government for issuing unfair election laws, opposition sources said.

An executive meeting of the National League for Democracy (NLD) - which is headed by Nobel Peace Prize laureate Aung San Suu Kyi - decided to sue the government over election laws promulgated last week, NLD Rakhine member Aye Tha Aung said.

He said the NLD found clauses that excluded the participation of Aung San Suu Kyi and other political prisoners from the election process as unlawful.

Under the Political Party Registration Law promulgated last week, the junta has prohibited people currently serving prison terms from being members of political parties.

Suu Kyi, who is serving an 18-month house detention sentence, must be dropped form the NLD party rolls should they wish to registered to contest this year's election, which they must do within the next 60 days.

The NLD has yet to decide whether or not to register to contest the election, a date for which has not yet been set, Aye Tha Aung said.
