Fabien Galthié is set to take Montpellier president Mohed Altrad to an employment tribunal over his suspension as director of rugby.
Galthié was temporarily suspended in December with Jake White brought in as a consultant to effectively replace him after a run of eight losses in nine games.
That suspension ended at the end of January, but having returned to the club for one day, Galthié left the club again and feels his role no longer corresponds to the contract he signed.
As a result he and Altrad will meet on March 30th to try to find an amicable solution to the problem but if none is found they will have to seek judicial intervention.
The financial aspect is key, with Galthié owed around €2M from the remainder of his contract which runs through to 2017 according to Rugbyrama.
While Galthié has not returned to the Stade Yves du Manoir since January 27th, he has continued his job as a consultant on France Televisions, notably during the Six Nations.
For a long time regarded as the favourite to succeed Philippe Saint-André as France coach, Galthié is now an outsider for that job, with Raphaël Ibanez being tipped for the position.
