McLaren has filed with the FIA International Court of Appeal against the overturned Monaco Grand Prix result, but the classification dispute is no longer the story that matters most. Buried in Document 99, the stewards’ own ruling on the Gasly right of review, is paragraph 42. In it, the stewards confirm explicitly that no regulation exists giving them the power to undo a penalty already served during a race. That single paragraph gives every team in the paddock a new playbook. Serve a penalty you believe is wrong and the door closes permanently. Leave it unserved, take the extra hit, then fight it afterwards with data. The Monaco measurement error was a technical failure. What paragraph 42 has created is a governance one.

Key Points: McLaren FIA appeal Monaco Gasly penalty
- McLaren files with the FIA International Court of Appeal against the decision to overturn Gasly’s Monaco pit lane penalties
- The first timing zone at Monaco’s pit entry was measured at 2692cm. The actual shortest driveable distance was 2615cm. That 77cm gap made the 60km/h limit mathematically impossible to meet
- Gasly reinstated to third. Hadjar loses his first Red Bull podium. Piastri drops to fifth. Russell falls from third to twelfth, losing 15 championship points
- Document 99 para 42: the stewards confirm no regulation exists giving them power to undo a served penalty. Unserved penalties applied to race time post-event can be reversed. Served penalties cannot
- That distinction gives teams a reason to leave a questionable penalty unserved, take the extra hit, and fight it afterwards with data
- Real-time penalties now look weaker. Final classifications no longer feel settled at the chequered flag
What Happened in Monaco
The pit lane speed limit at Monaco is calculated as average speed across timing zones: distance between two loops divided by the time taken to pass between them. In the first zone at the pit entry, the Official Timekeeper applied a distance of 2692cm. Post-race LIDAR scanning established the actual shortest driveable distance was 2615cm. That 77cm gap meant the system was recording cars as faster than they actually were. The 60km/h limit was unachievable in that zone.
Six speeding reports arrived during the race, all from that same first zone. After the third, the stewards queried Race Control, finding it unusual that so many were coming in at exactly 60.1km/h. Race Control checked with the Official Timekeeper and came back clear: no issue, data is accurate. The stewards had no knowledge the breaches were all in the same timing zone. Document 99 records that fact explicitly. They were unaware until June 10, three days after the race.
The barrier layout at Monaco’s pit entry also changed between 2025 and 2026, enabling a shorter trajectory through that zone than was possible in previous years. The same measurement process used at every previous Monaco Grand Prix didn’t account for it.
Alpine pursued a right of review. The stewards calculated that if Gasly had been averaging exactly 60km/h, he would have covered 2673cm and 2670cm in the recorded times, sitting between the applied distance and the theoretical shortest. Their conclusion, approaching beyond reasonable doubt in their own words, was that Car 10 did not exceed the speed limit. His two penalties were cancelled. He was reinstated in third. Hadjar dropped off his first Red Bull podium. Piastri fell to fifth. McLaren, Red Bull and Mercedes were left to weigh their options.
“Such an outcome risks creating sporting inequity and undermining confidence in the consistent application of the FIA Sporting Regulations.”
McLaren, FIA International Court of Appeal statement
Paragraph 42 and What It Has Done
The Monaco classification dispute is a problem. Paragraph 42 of Document 99 is a bigger one.
In it, the stewards state directly that there is no regulation giving them the power to undo a served penalty. They acknowledge the penalties served during the Monaco race impacted strategies and results. They acknowledge questions will remain about whether those breaches were genuine. And they confirm their hands were tied. Once a penalty is physically served during a race, it is permanent. There is no mechanism to reverse it regardless of what evidence emerges afterwards.
Gasly’s penalties were different. They were applied as five-second additions to his race time after the chequered flag, not served mid-race. That made them eligible for reversal through the right of review process. Russell’s drive-through was served during the race. It can’t be undone. Now it is in writing, every team has to think differently when a penalty lands and their data says otherwise.
From the pit wall, the calculation is brutal. Serve a penalty you believe is unjust and the door closes permanently. You’ve lost the positions, absorbed the time cost, and have no route back even if the data later proves you were right. Leave it unserved, take the extra hit, and fight it afterwards with telemetry. If the review succeeds, you keep the result. If it fails, you have at least kept the argument alive rather than closing the door yourself.
This applies to everything. Pit lane speed. Track limits. Unsafe releases. Forcing a driver off the circuit. Anything where the pit wall believes its data tells a different story. A driver gets five seconds for cutting a chicane and allegedly gaining an advantage. The team believes he gave the place back. Old answer: serve it and argue later. New answer: don’t serve it, take the hit, and go to review. Because paragraph 42 tells them that serving it closes the door permanently.
The Problem This Creates
A penalty used to mean something immediate and settled. A five-second penalty issued on lap 40 changed the race. Teams adjusted strategy around it. Drivers managed the gap knowing it would be applied. The chequered flag closed the sporting contest and the classification followed.
Monaco has cracked that. If the reason to leave a questionable penalty unserved is now stronger than the reason to serve it, the chequered flag stops being the end of the sporting contest. It becomes the start of the legal one. The result becomes something to argue over, not something fans can trust at the flag. And the FIA’s ability to enforce decisions in real time, the thing that gives stewarding any meaning during a race, is directly undermined.
Both Red Bull and McLaren confirmed at the Monaco hearing that teams already know the pit lane speed calculation method is imperfect and adjust their procedures accordingly. Document 99 records it. If teams were already gaming the margins on pit lane speed before Monaco, the question of how far that behaviour extends to other penalty types after Monaco is not a comfortable one.
The right of review process Alpine used was legitimate. Their evidence was watertight. The stewards’ conclusion was reached with something approaching the highest judicial standard. None of that is the problem. The problem is what paragraph 42 now gives every team in the paddock.
Where It Stands
McLaren’s appeal is live. Mercedes are pursuing a right of review. Red Bull haven’t returned the third-place trophy. The FIA Court of Appeal process will take time. Barcelona has already happened. The championship is moving. Monaco still isn’t settled.
Isack Hadjar lost his first Red Bull podium to a measurement error that wasn’t his, wasn’t his team’s, and wasn’t caught in time despite the stewards flagging something was wrong mid-race. That doesn’t disappear regardless of how the legal process concludes.
It looks strange from the outside that McLaren, Mercedes and Red Bull are all filing appeals about a rival driver’s penalty rather than their own results. The reason is simple: they have no other legal option. Under the regulations, teams submit a notification of intention to appeal immediately, then have 96 hours to formally proceed. That window for the Monaco race result ran and closed before the FOM measurement error was even known. The error wasn’t confirmed until June 10, three days after the race. By then the Monaco appeal window was already shut. The teams couldn’t appeal something they didn’t know existed, and they didn’t know it existed until after the only window that would have allowed them to act had already expired. Document 99 was then issued at 11:30 on Friday during Barcelona, opening a fresh 96-hour window. That’s the only door the regulations left open. So they’re not appealing Monaco. They’re appealing the document that changed Monaco.
The FIA need to address paragraph 42 directly and quickly. That could be a regulation change, a clarification of the right of review process, or a clear ruling on when penalties can be challenged after a race. If they don’t, the next disputed penalty won’t be an edge case. It’ll be a template.
Coffee Corner Take
The Monaco measurement error was a genuine technical failure. The barrier layout changed between seasons, the timing process didn’t account for it, and seven drivers were penalised for exceeding a limit the system couldn’t correctly enforce. The stewards did their job in good faith with the information they had. When the right information arrived, they reached the correct conclusion. That part of this story is actually the system working, slowly and imperfectly, but working.
Paragraph 42 is where the problem starts. The stewards confirmed in their own document that no regulation allows them to undo a penalty once served. They put it in writing. They had to, because it was the honest answer to why Russell’s situation couldn’t be addressed in the same ruling. But by giving that honest answer, they also handed every team a reason to think twice before serving a disputed penalty.
Any team with real doubt about a penalty now has a reason not to serve it. The data usually catches up. The right of review process is proven. The worst case for not serving it is a drive-through and a post-race legal fight. The worst case for serving it is that you were right to doubt it, the evidence proves it later, and you’ve already lost the positions with no route back. That’s not a close call for a team fighting for championship points.
Think about what that means for wheel to wheel racing. A driver defends hard and gets five seconds for forcing someone off at the apex. The team believes the data shows he had the corner. Do they serve it? After paragraph 42, the answer is increasingly no. Not because they’re acting in bad faith, but because serving it when you believe you’re right is now provably the worst available option.
The FIA Court of Appeal ruling on McLaren’s case matters. What matters more is whether the FIA address the regulatory gap paragraph 42 has exposed. The power of an in-race penalty is now at stake. If it isn’t addressed before the next disputed call lands mid-race, Monaco won’t look like the start of a governance crisis. It’ll look like the warning that was ignored.
