Reigning world champions Red Bull will learn on Tuesday whether they have been successful in their appeal against Daniel Ricciardo's exclusion from the Australian Grand Prix.
Ricciardo finished the race in second place but was disqualified after stewards discovered that his RB10 had exceeded the fuel flow limit across the duration of the race.
Several teams sent representatives to the court hearing in Paris on Monday and Paul Harris QC, representing Mercedes, urged the FIA to enforce harsher sanctions on Red Bull, citing the example of BAR-Honda in 2005, who were banned for two races after contravening the technical regulations.
"We are, frankly, and with great respect, concerned that Red Bull have shown such a flagrant and deliberate disregard for these rules that there is a real risk they will do it again," Harris is quoted by Autosport.
"We are here to seek to ensure that that does not happen, we must have a level playing field going forward for the remainder of the season. We apprehend that the other teams represented here today [Lotus, McLaren, Force India and Williams] take the same view, which is why they are here today.
"We respectfully submit that the most effective way to ensure that Red Bull do not flount further instructions from the FIA is for this court to recognise the severity of their infringement and to impose a further sanction upon them which is to be suspended for the rest of the season, so that they are acutely aware."
Red Bull claims that they used their own measuring equipment after finding faults with the FIA's sensors.
"The only evidence car three [Ricciardo] has exceeded that flow rate was the measurement supplied by the fuel-flow meter [FFM]," Red Bull's representative Ali Malek QC.
"We say that there was strong evidence before the stewards that this FFM was unreliable. You will recall that passage in the technical directive, if it is obviously unreliable then it is correct to use the secondary method or the backup measure. We say that it was unreliable and therefore we were entitled to use the secondary measurement."
The FIA's representative, Jonathan Taylor, claimed that Red Bull should not be permitted to ignore the regulations.
"Why is it important?" Taylor said. "Sport has to be on a level playing field. It needs an authoritative way of measuring. A team can't pick and choose methods of measurement and when they do or don't use them."
