Nelson Piquet Snr is threatening to take Flavio Briatore to court in the hope of extricating his son from the deal in place with the disgraced Renault team boss.

Despite the 'crashgate' scandal that resulted in Briatore resigning from his position on Wednesday, and Piquet Jnr becoming virtually unemployable, the Italian still manages the young Brazilian.

Remarkably, Piquet Jnr has a contract in place that would see him give up 20% of his earnings to Briatore over the next 15 years.

Piquet Snr is now awaiting the verdict from the World Motor Sport Council hearing on Monday before determining whether to pursue a case against the 59-year-old Italian.

"I could not talk to other team members about it (the contract), because Nelsinho was working for Flavio and his management has a contract with the team," Piquet Snr told Auto Motor und Sport in Germany.

"Now I finally have something- contract violation - to put pressure on Flavio.

"If the FIA world council confirms the case, I will have a hold for going to court."

The WMSC meet in Paris to review their case, and issue any penalty, against Renault over charges of conspiracy relating to last year's Singapore Grand Prix.

In deciding not to dispute the allegation made by the FIA, Renault have effectively admitted conspiring with Piquet Jnr of causing a crash to the advantage of Fernando Alonso.

That is despite Briatore's assertion last Friday in Monza that no wrongdoing took place, and that he had the support of the team.

Briatore also commenced criminal proceedings that day against the Piquets concerning the making of false allegations and a related attempt to blackmail.

Former three-time world champion Piquet Snr, though, admits he has nothing to fear on that score, telling Briatore: "Just go ahead."

He added: "I have enough money to afford the best lawyers. And what is he going to trial for? Does he want to put the truth on trial?"

Piquet Snr, who initially blew the whistle on the saga to the FIA, believes Briatore felt he was fireproof given his prior standing in Formula One.

"At a certain point people like Flavio have so much power, they believe they can walk on water," remarked Piquet Snr.

"He obviously thought, even though there was lots of proof, no-one could catch him."

The WMSC, meanwhile, appear set to review their policy in relation to punishing team members following this latest story to damage F1.

Under FIA regulations, as neither Briatore nor Renault's former executive director of engineering Pat Symonds are now no longer associated with a licence holder - that applies to drivers and teams only - no formal action may be taken against them under the International Sporting Code.

Although the Council have unlimited power when it comes to imposing a penalty against Renault, they are now powerless to act against Briatore and Symonds, despite the severity of the case.

It is why an amendment to the ISC seems set to be debated, and if agreed upon, will allow the FIA to act in the future.
