The leader of Samoa's Democratic United Party or SDUP says it will be challenging in court the Speaker's ruling that the party is no longer recognised in parliament as a political party.
The Speaker's ruling last month also rejected its request for the standing orders to be amended to allow the SDUP's seven MPs to be recognised as the Opposition following the resignation of its former party leader, Le Mamea Ropati, and another senior MP.
The new leader of the SDUP, Asiata Sale'imoa Va'ai, says he has spoken to his lawyer and papers will be filed next week.
He says there are strong legal grounds for the speaker's ruling to be questioned again in court.
"We feel we need to oppose this as a opposition firstly, and secondly because of the unconstitutionality of the act."
