Räikkönen's Drivers' Championship was briefly put into doubt when race stewards began an investigation after identifying possible fuel irregularities in the cars of Nico Rosberg, Robert Kubica and Nick Heidfeld following post-race inspection. Their disqualification and a race reclassification would have seen Hamilton lifted from seventh to fourth in the race result. However the race stewards decided that no sanctions would be given, meaning the results would stand. McLaren appealed against the decision, however the FIA Court of Appeal rejected their appeal on 16 November 2007 thus confirming Räikkönen as the champion. As of the end of the 2020 Formula One season, Räikkönen's 2007 title triumph remains the most recent World Drivers' Championship win for a Scuderia Ferrari driver.
