Barcelona: McLaren and Red Bull have formally lodged an intention to appeal the FIA's decision to restore Pierre Gasly's podium finish from the Monaco Grand Prix, as per reports by RacingNews365.

The developments follow an announcement Friday stating that Alpine's Right of Review challenge against two separate five-second time penalties issued to Gasly had proven successful, a ruling that reinstated the French driver to the third-place position he secured on the track.

Evidentiary material provided by Formula One Management (FOM) during the regulatory hearing revealed a physical discrepancy regarding the length of the initial electronic timing loop embedded within the pit lane. The loops are utilised to calculate distance alongside the duration required to traverse the sector to determine vehicle speed.

The governing panel determined that the primary loop was 77 centimetres shorter than official specifications indicated. Consequently, if a competitor approached the pit lane entrance at the maximum allowable threshold of 60 kph, the compressed measurement interval could cause the system to record an infraction even if the driver did not exceed the actual speed limit.

While race stewards previously noted an anomaly when five of the six recorded pit lane speeding violations registered at exactly 0.1 kph over the regulated limit, they were unaware of the 77-centimetre structural variation at the time of the initial ruling.

Based on the new telemetry data, Gasly's penalties were nullified, returning him to third place. The decision demoted Red Bull's Isack Hadjar to fourth, stripping the driver of his maiden podium with the squad, while McLaren's Oscar Piastri dropped to fifth.

Piastri was among the competitors penalised for travelling at 60.1 kph through the pit lane entry, subsequently serving a mandatory five-second stationary penalty during a scheduled pit stop before finishing the race within a five-second window behind Gasly.

RacingNews365 reports that McLaren and Red Bull have contested the FIA's retroactive decision to reinstate Gasly, rather than challenging the baseline penalty issued to Piastri during the Monaco event.

Formula One regulations mandate a 96-hour window for teams to submit appeals, a deadline that expired Thursday for the original race results. However, by signalling their intent to appeal the newly issued governing decision, both McLaren and Red Bull have secured an additional 96 hours to determine whether they will advance a formal legal appeal.
