Northamptonshire-based Mercedes must wait until tomorrow to hear whether they will be punished for their controversial tyre test.
The president of the FIA tribunal in Paris sat for more than six hours. It was brought to a halt at around 4:45pm local time.
Pirelli told the FiA Tribunal hearing the Mercedes tyre test case that the FIA had no jurisdiction over the tyre supplier.
Dominique Dumas, for the tyre firm, said:
"Pirelli is only exercising the rights which have been conferred upon it by the FIA. We are unable to understand the disciplinary process. Ferrari and Red Bull Racing have confirmed that they have no grievances against Pirelli.
"The claims are unfounded because it has been recognised that Pirelli has not violated the international sporting code.
"Pirelli has no FIA licence. It is a supplier amongst many other suppliers."
Mercedes Team Principal Ross Brawn has been giving evidence in defence of the Brackley-based F1 team.
Giving evidence Brawn called for "perspective" over the significance of the data gathered by his team during the Pirelli test.
Brawn, who previously revealed the final decision to agree to the Pirelli test was his alone, said access to telemetry data was an "inevitable consequence" of the work being done, but said Mercedes sought to keep their exposure to it "at a minimum".
He conceded the test in a 2013 car "could be perceived as an advantage", but said nothing was learned that had not already been established during the weekend of the Spanish Grand Prix.
"We didn't know what the tyres were and we didn't know what the detailed objectives were of what Pirelli were doing.
"We always work quite frankly on the principle that no information is better than bad information. So I don't see how we could have used any data that resulted from the Pirelli test."
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."
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.
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.
Brackley-based Mercedes are appearing at a tribunal over a controversial tyre test.
The team insist that they gained no benefit from the Pirelli test as the data was for the sole consumption of the tyre manufacturer.
Mark Howard QC, for the FIA, said telemetry data was transmitted back to Mercedes engineers and that they could not help but benefit.
"Running the car for three days at least informed Mercedes that they did not need to change the cars. That in itself would be valuable information.It is not beyond the bounds of possibility that some defect would have become apparent in the three days track testing, and it cannot seriously be suggested that Mercedes would not seek to remedy that defect.We would suggest that it is difficult to say Mercedes obtained no benefit from the test.
Brackley-based Mercedes are at an FIA tribunal in connection with their controversial Pirelli tyre test.
Mercedes' defence rests heavily on their assertion that they were given permission by FIA race director Charlie Whiting to use their current 2013 car at the test.
However, Mark Howard QC, speaking first on behalf of the FIA as the body's legal representative, said Whiting's consent was "irrelevant".
Howard said that Whiting was not authorised to amend Article 22 of the sporting regulations - which covers the ban on in-season testing - saying such a move could only be undertaken by the FIA's World Motor Sport Council.
The FIA's hearing into last month's contentious Mercedes and Pirelli tyre test got under way in Paris this morning.
The Brackley-based F1 outfit are appearing at the tribunal after they appeared to contravene the FIA's ban on in-season testing by their current car and regular drivers in a three-day, 1,000-kilometre test held in conjunction with Pirelli in May.
Team principal Ross Brawn was a witness for the Mercedes delegation, with Pirelli motorsport director Paul Hembery appearing for the Italian tyre manufacturer.
Legal representatives of Ferrari, McLaren and Williams were also in attendance, as was Red Bull team principal Christian Horner.
Nico Rosberg will be on pole for tomorrow's Bahrain Grand Prix in his Mercedes.
It's the first time the Brackley based team has had back-to-back pole positions since their return to Formula One at the start of 2010.
Rosberg pipped reigning world champion Sebastian Vettel for Red Bull and Fernando Alonso in his Ferrari.
His Mercedes team mate Lewis Hamilton was fourth fastest, but will start ninth on the grid after being handed a five-place penalty after his gearbox broke and his mechanics had to fit a new one.
Lewis Hamilton's first day behind the wheel of his Mercedes F1 car built at Brackley in Northamptonshire resulted in a crash into a tyre barrier. It was on the second day of testing at the Spanish Circuito de Jerez this morning.
The 28-year-old from Stevenage locked up into turn six and ploughed through a gravel trap into the tyre barrier. It's thought a fault in the front suspension caused the crash.
Yesterday Hamilton's team mate Nico Rosberg ground to a halt after just 14 laps when an electrical fault led to a fire in the rear of the new Mercedes.
