Brawn: FIA right to ban off-throttle diffusers
"Leaving things as they were, we were going to get protests and we certainly did not want that," the Mercedes GP team boss told Autosport.
"Fundamentally I would rather leave things alone, but what I would not want to see is a lot of protest and F1 getting into a mess and into issues and the appeal court.
"We have all been there, and we all know what happened with the diffusers a couple of years ago. This is different because the FIA were completely happy with the legality of diffusers, but now they are saying, 'somebody made a point and we can see it is a valid point so we want to control this'.
"Once you reach this stage you have to go down that route, and you cannot do anything but. The FIA are saying: 'we are not comfortable; some teams are saying we are going to protest, and we have to resolve it'.
"And I think the time we were given to resolve it was a good compromise, because the teams concerned could have protested it a few races ago, but they agreed to hold off and let everyone find a solution and get to where we are today."
