On 19 April, the FIA tribunal found in favour of Ferrari and Renault's protest of the Brazilian Grand Prix result. Piquet and Rosberg were disqualified and Prost was awarded the win. The other finishers, including some like title contender John Watson who had also been racing underweight, but had not been protested, were moved up the results accordingly. This gave Prost the lead in the world championship, with 18 points to Lauda's 12 and Rosberg and Watson's 8. The tribunal also ruled that after future races, all cars must be weighed before liquids were topped up. The FOCA teams requested a postponement of the next race, the San Marino Grand Prix, until July to allow consideration of the effects of the judgement, on the grounds that it changed the regulations of the sport. The race organisers refused to delay the race, which went ahead without the majority of the FOCA teams.
