The rivalry reached its peak at the end of 1989, when the title was to be decided between Senna and Prost at Suzuka. The two McLarens collided at the Casio Triangle chicane when Prost blocked an attempted pass by Senna. Prost walked away while Senna returned to the track. Senna went on to win the race, but was later disqualified in a highly controversial ruling over his path back to the track, as his car was pushed through the road around the chicane. After an unsuccessful appeal by McLaren, Senna received a further US$100,000 fine and a six-month suspension, leading him to accuse FIA president Jean-Marie Balestre of favouring his compatriot Prost.
