The Samoa Democratic United Party or SDUP has filed legal action against the speaker, Tolofuaivalelei Falemoe Leiataua, for refusing to recognise the party as the official parliamentary opposition.
The SDUP claims this loss of recognition violates standing orders, is discriminatory and an abuse of parliamentary process.
The speaker had ruled that the party did not have the necessary eight MPs to be recognized as the opposition.
Earlier the SDUP had lost two MPs, including its former leader, Le Mamea Ropati, after he was deposed by his deputy, Asiata Sale'imoa Va'ai.
