Real Madrid, Atletic Club and Barcelona have dragged LaLiga to court over the agreement to work with global investment firm, CVC.
Last Friday, 37 of the 42 LaLiga clubs approved the agreement to work with CVC for the LaLiga Impulso - or Boost LaLiga, in English - project.
However, Atletic Club, Real Madrid and Barcelona did not vote for the proposal and have decided to launch a legal action.
The three clubs are the most vocal opponents so far to the agreement for almost two billion euros to be put into LaLiga in exchange for a future percentage of audiovisual rights money.
"Athletic Club, Barcelona and Real Madrid hereby inform that legal action has been taken against the agreements adopted by the LaLiga assembly on December 10, which approved the so-called Proyecto Impulso that LaLiga intends to engage in with the private equity fund CVC, on the grounds that this is an illegal transaction which causes irreparable damage to the entire Spanish football industry and which flagrantly violates the most elementary principles of Spanish sports law and LaLiga's own statutes," a joint statement from these three clubs said on Wednesday.
The LaLiga and CVC saga, therefore, appears to be far from over.
