Nico Hulkenberg has been handed a 20-second penalty following a protest by the Force India team in Singapore.
The Silverstone-based squad protested against Hulkenberg after its own driver Adrian Sutil was given a 20-second penalty for having gained from going around the outside of Turn 7 on the opening lap of the race. The team felt the Williams driver has also gained from cutting a corner.
Sutil, who had finished the race in eighth, was demoted to 10th, but has now moved to ninth following Hulkenberg's penalty.
The Williams driver, meanwhile, drops to 10th.
The penalty means Force India is back in front of Williams in the Constructors' Championship. Force India has also confirmed it has withdrawn its protest against Sutil's penalty decision.
Ferrari's Felipe Massa, having finished in 10th, moves up to eighth.
