"Going by what the regulations were supposed to have meant, Red Bull had contravened them. Going by what they actually said, they had not. Reducing the torque demand at full throttle from one race to the next is very different from reducing the full-throttle torque demand of the engine on that day as a certain engine speed is reached.
Red Bull chose to read the regulation in a way that meant the latter - and its map did not contravene that reading. The FIA meant torque demand relative to what the engine is ultimately capable of. Red Bull chose it to mean torque demand relative to what that engine was capable of with that map on that day - and on those terms there was no reduction, and therefore no offence."
