The Suva High Court will hear the legal challenge brought by sacked members of Fiji's Great Council of Chiefs early next month.
The legal papers for a judicial review have been filed by lawyers for the ousted chairman of the council, Ratu Ovini Bokini, and three other chiefs
They have named the interim minister for Fijian affairs, Ratu Epeli Ganilau, and the interim prime minister, Commodore Bainimarama, as defendants.
After a hearing in chambers, Justice Filimoni Jitoko has given state lawyers 14 days to file their affidavits and set August the 3rd for the start of the case in court.
Most members of the Great Council of Chiefs were sacked after they refused to endorse President Iloilo's nomination of Ratu Epeli Nailatikau as vice president in April.
Meanwhile, the review of the membership of the Chiefs Council is still going ahead by a team headed by Col Apakuki Kurusiga subject to any High Court ruling that may be delivered.
