The Fiji information ministry says the general secretary of the Oceania Football Confederation, Tai Nicholas, has pleaded guilty to the charge of contempt of court.
The ministry says the lawyer representing Nicholas in the High Court formally entered the plea for his comments made last year that there was no judiciary in Fiji.
Fiji's attorney-general brought court proceedings against Nicholas, claiming the comments scandalised the court and posed the risk of undermining public confidence in the independence and impartiality of the Fijian judiciary and the administration of justice in Fiji.
The ministry says a related case has been taken against the Fiji Times Limited and its editor and publisher for publishing Nicholas' statements.
Fiji's judiciary was reconstituted in 2009 after the regime sacked it in response to an appeal court decision declaring the post-coup interim government illegal.
