Barcelona are to boycott Tuesday's Spanish football federation (RFEF) meeting which will decide where the Spanish Cup final will take place, in protest over their perceived treatment by referees this season.
"We've decided not to attend this meeting of the federation as a sign of disenchantment. The force of our objective arguments has not been taken into account, so we are relying on the decision of the RFEF," club spokesman Toni Freixa said.
The Catalan club are furious with match officials after defender Gerard Pique was sent off in Saturday's Primera Liga 3-1 win over Sporting Gijon at the Nou Camp.
Pique claimed after the match that his sending off was "premeditated" by the referee and the club are appealing the decision.
A decision on where the Cup final between Barcelona and Athletic Bilbao will take place has already been postponed because of differences between the clubs over the venue.
RFEF vice-president Joan Gaspart has said that if no decision is reached on Tuesday the venue will be decided by drawing it out of a hat.
