French football authorities look set to spend significant amounts of time and money in the courtroom as several clubs have announced they will take cases to the country's highest administrative court over the decision to end the Ligue 1 and 2 seasons.

Lyon criticised the 30 April ruling made by the French league (LFP) to declare the season over and declare Paris Saint-Germain champions, following an announcement by the government that football could not restart until September because of the coronavirus pandemic.

The club from France's second-largest city, who have reached this season's Champions League last 16, were left seventh in the standings and outside the European qualification places when the season was halted.

An administrative court in Paris has already rejected an appeal from the club, but Lyon said that "the administrative tribunal did not rule on the merits of the case" and warned they would take the matter to the Council of State, the country's supreme court for administrative law.

Amiens, who are contesting their relegation to Ligue 2 and whose initial appeal was also turned down last week by the Paris court, have indicated their plans to turn to the Council of State as well.

Ligue 2 side AC Ajaccio said that they would also take a case to the Council of State after their request for promotion play-offs to be staged was rejected.

The French Olympic Committee has rejected requests by Troyes, Clermont and AC Ajaccio for playoffs to be used to decide on promotion to Ligue 1.

With 10 games remaining, Lorient (54 points) were crowned champions and promoted to Ligue 1 alongside RC Lens (53). Third-placed AC Ajaccio (52), fourth-placed Troyes (51) and fifth-placed Clermont (50) will all remain in Ligue 2.

Following a public plea to President Emmanuel Macron, Lyon president Jean-Michel Aulas has also written a letter Monday to France's prime minister and sports minister urging them to reconsider the decision, with the government expected to announce a further loosening of the lockdown next week.

"Could we imagine that 2 June is also a great opportunity to rectify the mistake concerning French football and to allow, with a health protocol used everywhere, a gradual resumption of training and, why not, a resumption of the 2019-20 season over the months of July or August?" Aulas said.
