Here we look at some other on-track controversies in Formula One's recent past.
SENNA v PROST - 1990 JAPANESE GRAND PRIX
Ayrton Senna complained that pole position was wrongly situated on the track and demanded to be moved into the racing line. When his request was rejected and he was overtaken by title rival Alain Prost at the start, Senna took out the Frenchman on the first corner to secure the world championship.
Michael Schumacher's Benetton had suffered irreparable damage by the time it was involved in a collision with Damon Hill's Williams in the season-ending Australian Grand Prix in Adelaide in 1994, a crash that forced the British driver out of the race and ensured Schumacher secured his first F1 drivers' title. Schumacher has always maintained that it was a racing incident.
Three years later Schumacher collided with another rival, Jacques Villeneuve, in a final-race shoot-out at the European Grand Prix in Jerez. However, the Canadian, who had been attempting to overtake Schumacher when the collision occurred, finished third to take the title while Schumacher - whose second place in the championship was later stripped from him - was forced to retire from the race.
FERRARI TEAM ORDERS - PART ONE
Schumacher, acting under team orders, passed Brazilian team-mate Rubens Barrichello who clearly slowed down in order to allow the German to win the 2002 Austrian Grand Prix and claim maximum points in the drivers' championship.
The German was jeered by the crowd, even when he attempted to allow Barrichello to stand on the top step of the podium at the post-race celebrations.
Nelson Piquet Jr revealed he had been ordered to deliberately crash during the 2009 Singapore Grand Prix to create the perfect environment for his then Renault team-mate Fernando Alonso to win the race. Team managing director Flavio Briatore and chief engineer Pat Symonds both left the team in the wake of the revelations. Briatore was given an indefinite ban from F1 by world governing body the FIA, with Symonds suspended for five years. Both later had their suspensions quashed in a French court, and Symonds is now back in F1 with Marussia.
Lewis Hamilton, then with McLaren, was initially promoted from fourth to third after race stewards at the 2009 Australian Grand Prix handed Jarno Trulli a 25-second penalty for passing the Briton behind the safety car. Hamilton and McLaren sporting director Dave Ryan insisted at the time no order was relayed from the team demanding he allow Trulli to pass. However, pit-to-car transmissions and an interview Hamilton gave immediately after the race contradicted their story, and resulted in the case being reopened. McLaren were found to have "deliberately misled" the stewards and both team and driver were disqualified from the classification in Melbourne. Ryan was subsequently sacked and the team handed a suspended three-race ban by the FIA.
FERRARI TEAM ORDERS - PART TWO
Ferrari were fined £65,000 by race stewards at the 2010 German Grand Prix after being accused of implementing a team order.
Following coded messages over the team radio, Felipe Massa eventually ceded a potential victory to team-mate Fernando Alonso, a move that sparked outrage at the time.
After meeting with the stewards, Ferrari were deemed in breach of article 39.1 of the FIA 2010 sporting regulations that states 'team orders which interfere with a race result are prohibited'. In December 2010 the article was deleted from the FIA's statutes.
