Fiji police are reported to be investigating the abrogation of the constitution by the military during the 2000 coup.
The Fiji Sun says the investigations follow a complaint from the president of the Fiji Citizens Freedom Movement, James Bachu, backed by an unnamed political party.
A police spokesman, Mesake Koroi, has confirmed they are looking at the actions of the military commander, Commodore Frank Bainimarama, and the removal of the former president, Ratu Sir Kamisese Mara.
But the secretary general of the ruling SDL Party, Josaia Diani, is quoted as saying bygones should be bygones and a case such as the one brought up by Mr Bachu would be cause instability in the country.
Mr Diani says Commodore Bainimarama stood his ground during the coup and acted in good faith, and should be commended that there was no bloodshed.
Mr Diani says during the coup people like Mr Bachu depended on the military for safety but now that normalcy is back and the constitution re-instated, they are attacking its actions when the country was on the verge of anarchy.
