Fiji's former ruling SDL party will file papers today to begin a High Court challenge of the overthrow of its government by the military last December.
Suva lawyer Tevita Fa says he was approached last month by the deposed prime minister, Laisenia Qarase, to begin the legal action against his ousting.
Mr Fa says they have 27 grounds on which to mount the challenge including the events of December 5th and what followed afterwards.
He says it has taken him weeks to collect the evidence but he is ready to proceed with the case.
The military lawyer, Lt Col Mohammed Aziz, says they have been expecting the move and will do their part once a summons is served on the army.
The interim attorney general, Aiyaz Sayed-Khayum, said yesterday the interim administration will not interfere with the independence of the judiciary.
