FIA was talked first, before Mercedes and finally Pirelli. Team boss Ross Brawn, race engineer Andrew Shovlin and team manager Ron Meadows was represents for Mercedes. Pirelli motorsport chief Paul Hembery is representing his company, with Formula 1 race director Charlie Whiting present for the FIA.
Red Bull team boss and Christian Horner and chief engineer Paul Monaghan are both present as observers. Ferrari, McLaren and Williams have all sent legal observers.
Christian Horner revealed his opinion with Sky Sports an exclusive interview, few Q&A added below there.
They [Mercedes] said that a reprimand might be enough and that it was a minor infringement. Would you want a sporting penalty?
CH: "It's for the Tribunal to decide, it's not for us to comment on what the penalties should be, but normally if you commit a sporting offence then it is a sporting penalty which goes with it."
What do you think a fair penalty would be?
CH: "That's down to the Tribunal, but the problem is that if it is only financial then that only becomes the cost of testing. The most important thing to come out of this is clarity; you are either allowed to test or you are not. Obviously, Ferrari have conducted a couple of tests which have come out of this, albeit in a 2011 car, which is within the regulations, but I think moving forward the most important thing is transparency and clarity because the way that test was conducted wasn't right.
"We raised a protest against Mercedes because in our opinion they breached the Sporting Regulations. It's been a fair hearing today and all the parties have represented their cases, and that's it."
What do you think of Mercedes' proposal that they are banned from the Young Driver Test?
CH: "I can't see how much of a sanction...They've already done their test with senior drivers so being banned from a Young Driver Test probably isn't much of a sanction."
