The FIA has now officially confirmed that the International Tribunal hearing regarding Mercedes and Pirelli will take place in Paris on June 20, a date that was expected over the Montreal weekend.
The FIA has also confirmed that Pirelli will be alongside Mercedes in the dock, despite the fact that the original protest was against the team.
An FIA statement today read:
Disciplinary procedure against Mercedes and Pirelli (2013 FIA Formula One World Championship)
On 5 June 2013, further to protests lodged during the 2013 Monaco GP by Red Bull Racing and Ferrari Scuderia Team against cars n°9 and 10 (Mercedes AMG Petronas F1 Team) for having conducted with Pirelli a three day tyre testing using a 2013 car on 15, 16 and 17 May in Barcelona, the President of the FIA, acting as the FIA Prosecuting Body, sent to the President of the International Tribunal a notification of charges against Pirelli and a notification of charges against Mercedes AMG Petronas F1 Team.
On 5 June 2013, Pirelli and Mercedes AMG Petronas F1 Team have been convened by the President of the International Tribunal to appear before a judging panel of the International Tribunal.
The FIA added: “The decision of the International Tribunal will be published as soon as possible after the hearing.”

That is what we are waiting to discover
