Mercedes could face tribunal after protests over tyre testing
FIA says it may impose penalties on team after Red Bull and Ferrari lodge official protests
The latest row engulfing Formula One could end up going before another hearing after Red Bull and Ferrari launched official protests against Mercedes, alleging the team breached rules by conducting in-season tyre testing with manufacturer Pirelli following the Spanish Grand Prix two weeks ago.
After the hearing, motor sport's governing body said "the stewards [present] will write a report to the FIA, which may bring the matter before the International Tribunal".
The FIA gave no further details when this might happen. The next race is in two weeks in Canada.
The sport's governing body also warned Mercedes over its conduct and said its tribunal "may decide to inflict penalties that would supercede any penalty the stewards of the meeting may have issued".
Earlier, the team principals of Red Bull and Lotus - which did not lodge a formal protest - expressed their annoyance at what they felt was secretive testing by Mercedes. "We feel it's not in line with the rules," Red Bull's Christian Horner said. "We just want clarity." Mercedes has been fast in qualifying - securing a fourth straight pole for Monaco - but had struggled with durability during races and Rosberg's win was the team's first of the season.
Mercedes team principal Ross Brawn said "it wasn't a secret test". He added: "It was up to Pirelli to spread the information. It wasn't up to us, it was their test. Pirelli has been asking teams to help them out for 12 months and people haven't been supporting them."
