Paul Harris QC, representing Mercedes, rejected the FIA's stance by insisting it was "irrefutable" that Pirelli controlled the running of the car and the driver for the duration of the test.
– Paul Harris QC
Pirelli did it all. They were in charge of it all and it's obvious why - it was a Pirelli test.This was not a test undertaken by Mercedes. They are critical words in the text of Article 22 - 'undertaken by'.
Harris said Mercedes' access to telemetry was purely to ensure the safety of the car and driver while on track, and cited similar tests conducted by Pirelli with Lotus and Ferrari in recent years, in which the F1 teams also had access to car data.
