Pierre Gasly has been reawarded a podium finish for the Monaco Grand Prix after Alpine's appeal into his post-race penalty was successful.
Gasly finished Monaco's race in third place, only to be hit with two five-second time penalties after the race for pit-lane speeding which bumped him back down to seventh.
He was judged to have gone 0.1km/h and 0.4km/h over the limit in two different trips to the pits.
Alpine protested that result and on Thursday were granted an appeal hearing after meeting the criteria for presenting the FIA with new, relevant and significant information not available to the stewards at the time.
In the follow-up hearing, the FIA deemed he did not exceed the 60 km/h speed limit. The stewards accepted new evidence -- including evidence provided by Formula One Management (FOM) -- that the official measurement used for calculating the pit-lane speed was incorrect.
This evidence showed the distance used to calculate speeds in the first pit-lane timing zone was longer than the shortest route actually available to drivers following changes to the curved pit-entry layout.
The official timing system used a distance of 2692 cm (26.92 m) for the first pit-lane timing sector.
However, FOM's own analysis found that the theoretical shortest route between the same two timing loops was only 2615 cm (26.15 m) -- 77 centimetres shorter.
The stewards had a level of proof described as "comfortable satisfaction" and "beyond reasonable doubt" that Gasly's car had not exceeded the limit on either occasion.
It means Gasly, who had called the penalty "heartbreaking" and the worst sporting moment of his career, moves back up to third.
The Frenchman said it had always been a dream of his to celebrate on the Monaco podium, which he was unable to do. Isack Hadjar had joined Kimi Antonelli and Lewis Hamilton on the podium, but he drops down to fourth as a result of the appeal hearing -- losing his first Red Bull podium as a result. Oscar Piastri drops to fifth, Liam Lawson to sixth, and Arvid Lindblad to seventh.
Gasly was one of five drivers to have been awarded penalties for pit-lane speeding during the race. Mercedes driver George Russell was one of them, but he was supposed to serve it during the pit-stops during a late safety car stoppage.

A communication mix-up meant Mercedes started work on his car when he was supposed to be stood stationary for the five seconds. Because he did not serve it at the first possible opportunity, he was given a drive-through penalty, which he served when the race restarted while running in third -- that elevated Gasly to third on track.
The FIA cannot overturn penalties served in the race.
A Mercedes source told ESPN the team are "livid" at the outcome of Alpine's appeal, having raised concerns to the FIA about the pit-lane measurement system on Friday ahead of the Monaco race weekend.
The team had instructed its drivers to take extra precautions when entering the pit-lane, too, including going wider on entry and lifting off to ensure they did trigger the incorrectly measured system. The team is not able to appeal or protest.
The incident likely cost Russell 15 points -- he is 68 points behind teammate Antonelli in the championship.
Russell had gone to see the stewards at race control during the Monaco red-flag stoppage to ask for the drive-through penalty to be applied to his race as a time penalty after the race, knowing there might be a chance of overturning it.
"That's kind of why I was pleading with the FIA at the red flag to not serve that primary [drive-through] penalty and to at least penalise me after the race if they feel that it was justifiable because once you serve the penalty, there's no turning back," Russell said on Thursday.
In a statement, Alpine said: "We welcome the decision made by the FIA to deem our Right of Review as admissible following the final classification of last weekend's Monaco Grand Prix ... We would like to thank the FIA and Formula One Management for its transparency and co-operation throughout the Right of Review process and for reaching this decision. The team's focus is now very much on this weekend's Barcelona-Catalunya Grand Prix and striving for the best possible result with both of its cars."
In a statement of their own, Formula One said: "As part of the right of review process relating to Monaco, we have proactively assisted the FIA in gathering all the relevant information to help inform the steward's assessments.
"We measured the relevant areas in the pitlane identically to the 2025 event and followed procedures in the usual way. However, the process has identified a measurement discrepancy. Like everyone in the sport we strive for the best results and, as always, any improvements or refinements that are identified as being required in light of this situation will be implemented."
