McLaren and Red Bull have both lodged notice of their intention to appeal the FIA’s decision to rescind Pierre Gasly’s pitlane speeding penalties from the Monaco Grand Prix.

The Alpine driver had his penalties rescinded by the FIA after the team pursued a right of review.

The unusual decision was made after it emerged that Formula One Management had made a measurement error relating to the pit distance used to calculate speed.

It has been determined that there was "a significant delta in the distance used to calculate the speed and distance which could be driven...and which appears to have been driven".

McLaren, whose driver Oscar Piastri was classified fourth in the original result but now moves back to fifth with Gasly reinstated, had been an interested party in the FIA hearing at Barcelona.

It also has a heavy involvement in what happened because Piastri was one of several other drivers who also picked up speeding penalties. As he served the penalties during the race, he could not have had his punishment rescinded.

McLaren had argued in the Alpine hearing that there was no need for the FIA to change the result because there is a well-known risk of discrepancies in the pitlane speed calculation, teams and drivers regularly adjust their processes, and there was some conjecture on how the pitlane measurement always aims for the shortest distance.

However, Alpine managing director Steve Nielsen said on Friday in Spain that "alarm bells" had rung after Gasly was flagged repeatedly for speeding in Monaco without anything being apparent in the team's own data so it felt it must be an external factor and nothing Alpine could do anything about.

He said, "99 times out of 100, and it's probably more than that, when you get pinged for pitlane speeding, you don't even question it. Some guy comes on the radio and says, 'you can see it in the data', and you just take the penalty.

"This time was different. It wasn't in our data... That's the biggest alarm bell for us."

Shortly after the FIA published its statement that Gasly had been awarded his podium back, McLaren elected to lodge a notification of intention to appeal, with Red Bull confirming just under an hour later that it had done likewise.

It had finished on the podium with Isack Hadjar but now falls to fourth.

Under the FIA’s judicial and disciplinary rules, such a notification has to be lodged within one hour of any decision made by officials.

However, this does not necessarily mean that McLaren or Red Bull will follow through with the appeal, as they have 96 hours to decide if they do want to go ahead with the action or withdraw it.

The notification of appeal now gives McLaren and Red Bull some breathing room to decide its next steps.
