ROME, Aug 23 (Reuters) - The Italian football federation wrote to FIFA on Wednesday saying it would impose extra sanctions on Juventus if the club turn to a civil court to try to overturn their relegation after a match-fixing scandal.
The letter, confirmed by the Italian federation (FIGC), said FIGC would not 'hesitate to launch the sanction process' if Juve lodge an appeal with the regional Lazio court, as they have said they will.
FIGC said Juve have not yet lodged their appeal with the court.
A soccer tribunal ruling on the match-fixing scandal stripped Juve of their last two Italian titles and demoted them to the second division, where they will start next season minus 17 points.
The FIGC said that under its statute member clubs accept to abide by sports authorities' rules, forsaking their right to turn to civil courts which are outside the sports justice system.
It said it had received a letter from FIFA on Tuesday, reiterating that clubs appealing to civil courts should be punished for that.
Juve said on Monday they would appeal to the Lazio court after they failed to persuade the FIGC to overturn the relegation verdict last week.
FIFA have threatened the Italian Football Federation (FIGC) with heavy sanctions, should they not step in to block Juventus' appeal against their punishment in the match-fixing trial.
Italian clubs could be banned from playing in international competitions and the national team pulled out of the qualification campaign for Euro 2008 if the FIGC do not take any action.
Taking a matter to a civil court is against FIFA's rules and could lead to the Federation being suspended.
That in turn could lead to the exclusion of Italian clubs and the national team from international competitions.
Article 61-2 FIFA's statutes claims that `Recourse to ordinary courts of law is prohibited unless specifically provided for in the FIFA regulations'.
Article 61-3 continues: `To ensure the foregoing, the Associations shall insert a clause in their statutes stipulating that their clubs and members are prohibited from taking a dispute to ordinary courts of law and are required to submit any disagreement to the jurisdiction of the Association, the appropriate Confederation or FIFA.'
