Well, I'm going off a translated Tweet from a Dutch commentator here. It's possible he meant "stewards" instead of "courts". But I think he also mentioned that Frijns had twenty-five seconds added to his race time in the same Tweet.
It still makes no sense for Bianchi to go to a court of law, though. He'll be a pariah in the paddock the minute he does it - if it can happen to Andy Soucek, it can happen to Jules Bianchi. No-one wants a driver whose first response is legal action when he doesn't get his way. Okay, so Soucek was taking action against a team and Bianchi is (supposedly) taking action against a driver, but it's still not going to end well for Bianchi.
The only way this could possibly be true and still make any sense is if Ferrari promised to place Bianchi in a Formula 1 team in 2013 - probably Sauber - but only on the condition that he won the Formula Renault 3.5 title. If not, the deal was off. Frijns, on the other hand, has been given a day with Sauber at the Young Driver Tests, and he has publicly said that he is driving for his career here. He has no real sponsorship; his family's business - Frijns Industrial Group - has some presence in sponsoring him, but I've heard that they're limited to sheet metal fabrication or the like. Bianchi might only be taking legal action against Frijns if he thinks Frijns deliberately pushed him off the circuit, thereby depriving Bianchi of his shot at Formula 1 (though this depends on Frijns knowing that Bianchi was going to be placed if he won) for the sake of his own. He's still going to have a devil of a time proving it, though. The stewards gave Frijns a twenty-five second penalty for causing an avoidable collision, and there doesn't appear to have been anything malicous about the contact.
Either way, I agree that Jules Bianchi is over-rated. he set the world on fire in Formula 3 and was touted as the Next Big Thing, but in two attempts at winning the GP2 title, he failed twice. He got a reputation as a bit of a crasher, and while he's had a better time of it in Formula Renault, I would not be surprised if Ferrari placed him in the team and then had them support Bianchi first all season long. Kevin Korjus did really well last year, but this year he's been let down by poor reliability, dud strategies, and has generally had a very poor run of luck. All of that stopped when he moved to the Gravity-Lotus team mid-year (even if he was only racing for minor points). If Tech 1 Racing were paid by Ferrari to support Bianchi from the first race in Aragon, then that makes me like him even less. Bianchi already had his shot. He shouldn't get a second bite at the apple when it means another talented driver has to miss out.
