The United Front for a Democratic Fiji says the regime's proposed Fiji First party has committed a clear cut breach of the Political Parties Decree by using the name of a previous party.
The Front's co-ordinator, Mick Beddoes, recently lodged an objection to the registration of Rear Admiral Frank Bainimarama's proposed party, with the Supervisor of Elections.
Mr Beddoes says he hasn't had a response yet from the Supervisor Mohammed Saneem.
A complaint has also been lodged by the Fiji First Party, which was wound up by the regime last year.
Fiji First is the registered name of a previous political party that contested the 2006 general elections and Mr Beddoes says approval of the use of the name would be a breach of section eight of the Political Parties Decree.
"How the supervisor of elections decides on this is a very important matter and people should pay attention to this because this will demonstrate beyond any reasonable doubt that the laws in Fiji are only for a certain group."
Mick Beddoes says he has spoken to a couple of lawyers who say it's a black and white breach.
