The General Secretary of Fiji's National Federation Party, Pramod Rae, has raised the prospect of some parties opting out of the 2009 general elections if major changes are made.
Political parties, including the ousted SDL, are beginning to think about preparations for the proposed poll.
But the interim Prime Minister has said the SDL will not be able to stand.
Mr Rae says if binding provisions are brought in to control any future government, then that would change the political landscape and parties might not choose to take part in elections.
He believes neither local political parties nor outside influences such as the EU or the Commonwealth had been expecting such major alterations when a timetable for democratic elections was agreed:
"I don't think anyone envisaged fundamental, philosophical changes to the political scene. Now that these things are coming around, those time frames may no longer be realistic. Of course if that sort of thing happens then the sanctions that go with those demands from those international bodies, the EU and other groups may become more stringent."
