The 21-year-old Finn, who has competed in just 23 single-seater races in his career, is "on probation" for the early part of a season starting in Australia on March 4 when he makes his debut for Sauber.

	The hiring of the inexperienced Kimi Raikkonen, pictured, has caused controversy in F1.

"It is known that I am the one who voted against (Raikkonen) having a super-licence. Everyone else voted in favour," Mosley said in an interview with Australian Grand Prix organisers.

"I would say that ... probably our super-licence system is in need of an overhaul because there are very clear rules about how you get a super-licence -- you have to have won a Formula Three championship or you have to have had certain success in Formula 3000 -- it's all very clear."

Mosley said the "exception rule" was there to allow -- in exceptional circumstances -- drivers with great Formula One experience to make a comeback in the sport, as happened with former champion Alain Prost.

"That was the reason for the exception, and the exception is now used in Raikkonen's case to give him a licence.

"There is no question that he is obviously a very, very good driver and ... he will have done about 4,000 kilometres in a Formula One car before he gets to Melbourne.

"On top of that he is on probation for the first, I think it's three or four races. But it did seem to me that if you have criteria, you should follow them.
