The Spanish Football League is facing a race against time to stop a strike called by the national football federation to suspend all domestic competitions starting on Saturday.
The RFEF announced last week a strike to halt football over a dispute regarding government interference in the league's television rights.
At the heart of the dispute is a proposed law which would force the RFEF to sell television rights for the Primera Division collectively. Rights are currently sold on a club-by-club basis, leading to significant imbalances in club revenues.
At an extraordinary general assembly of the Spanish Football League (LFP) on Monday in Madrid, club presidents stood by their plan to switch to collective rights in order to increase the competitiveness of the league.
LFP president Javier Tebas said: "The threat of the strike exists. We fully support the Royal Decree (proposed law).
"We have presented a lawsuit because we believe this strike is illegal and can be very damaging.
"We are looking at an illegal strike and that is why we have gone to the judicial system.
"We've also requested that the Spanish Sports Council (CSD) grant us a temporary measure in view of the RFEF's petition to suspend the campaign.
"We hope the CSD will resolve this within the next two days."
The RFEF is against the proposed legislation because it would only receive 4.55% of pools revenue from the Spanish government, a figure the federation deems inadequate.
The RFEF has the backing of the Spanish professional footballers' union (AFE), which is also unhappy with its proposed share of the deal.
However, Tebas said the deal was fair.
"It's not true that the players will miss out on any rights," he said. "They are misinformed. The Royal Decree has benefits."
A conciliation meeting, to be attended by Tebas and AFE representatives, is scheduled for Wednesday.
"The conciliation act is a step that has to be taken when a strike is called," Tebas said. "We will sit with the Footballers' Union representatives and listen to what they have to say.
"It's not true that the players will miss out on any rights"
"I find it difficult that there will be an agreement in the conciliation act.
"In the meantime, we call on the RFEF to stop on the path they have pursued."
If there is a strike, the RFEF would prevent their referees from working the games.
"We have not considered the possibility of bringing in foreign referees," Tebas said. "If the high court declares the strike illegal and the CSD gives us the temporary measure, the Spanish officials will be obliged to referee."
If the strike does takes place, the Copa del Rey final between Barcelona and Athletic Bilbao on 30 May will be affected, as well as the final two rounds of Primera Division action.
