Northamptonshire-based F1 team Mercedes have mounted a robust defence of their controversial tyre test.
The team's lawyer cited similar tests conducted by Pirelli with Lotus and Ferrari in recent years, in which the F1 teams also had access to car data.
Ferrari were initially asked to respond to an FIA request for information relating to today's hearing over the tyre test they conducted with Pirelli earlier this year but as they used a 2011 car and test driver Pedro de la Rosa they were not summoned to appear before the tribunal.
However, Paul Harris, for Mercedes, hinted at dissatisfaction at that decision by saying he did "not accept that [by] Ferrari running a 2011 car, that that car does not confirm substantially to the 2012 or 2013 regs".
He added: "The changes between 2011 and 2013 cars are minuscule."
