Four-team legal battle erupts over Monaco GP podium after FIA measurement error

The 2026 Monaco Grand Prix podium was supposed to be settled. Instead, it has ignited one of the most complex legal disputes in recent Formula 1 history. Three top teams — Mercedes, McLaren and Red Bull — are separately challenging the FIA's decision to reinstate Pierre Gasly to third place, after a measurement error in the pit-lane timing system was discovered post-race. The FIA has set a virtual hearing for Saturday to hear Mercedes' case.

The measurement error that changed the race

The controversy centres on how F1 polices pit-lane speeding. The system does not use speed guns; it calculates a car's average speed by measuring the time taken to travel between two timing loops and dividing by the known distance between them.

After the Monaco GP, Alpine's successful Right of Review revealed that the distance FOM had recorded for the first timing zone — 2,692 cm — was wrong. A post-event LIDAR scan showed the shortest distance between the first and second loops was actually shorter. The discrepancy, described as being on the scale of centimetres, meant the system was over-reporting average speeds. Five drivers received penalties based on that erroneous data: Gasly (twice), George Russell, Lewis Hamilton, Oscar Piastri and Franco Colapinto.

Alpine presented this new evidence to the stewards, who deemed it "significant and relevant" and overturned Gasly's two five-second time penalties, restoring him to third place.

Why Mercedes is fighting for George Russell — and why it's different

Mercedes has formally lodged a petition for a Right of Review of the changed Monaco result, with the FIA confirming a virtual hearing on Saturday to hear the team's arguments. The team's interest is direct: George Russell was one of the drivers penalised for the same pit-lane speeding offence that was later proven to be based on incorrect measurements.

But Russell cannot simply receive the same remedy as Gasly. The critical procedural distinction is how each penalty was applied. Gasly's two five-second penalties were added post-race, so Alpine's Right of Review could simply remove them from the final classification. Russell's penalty, by contrast, had already been applied during the race, making it procedurally far more difficult to unwind. That is why Mercedes is seeking a separate review of the entire revised result, rather than an automatic reapplication of Gasly's remedy.

McLaren, Red Bull and the sporting fairness argument

McLaren and Red Bull have both notified the FIA of their intention to appeal Gasly's reinstatement. Their argument is straightforward and rooted in sporting fairness: if the timing error affected all five penalised drivers, then correcting the result for only one of them is inconsistent.

McLaren has publicly cited concerns over "sporting fairness" and "integrity" in its appeal. Red Bull has a more direct competitive stake: when Gasly was originally demoted to seventh, Isack Hadjar inherited third place and what would have been his first Red Bull podium. When Gasly was reinstated, Hadjar lost that result.

Some reports indicate that as many as three teams — Mercedes, McLaren and Red Bull — have now activated a Right of Review procedure over the Monaco outcome.

Current status: what happens next

• Pierre Gasly — His third-place finish stands for now, pending the outcome of the various challenges.
• Mercedes — The FIA will hear Mercedes' petition in a virtual hearing on Saturday.
• George Russell — His penalty remains a separate, more complicated issue because it was applied during the race rather than added post-race.
• McLaren & Red Bull — Both teams have lodged their intention to appeal, arguing that the stewards' decision creates an unfair precedent.

The legal fallout from Monaco is far from over. With four teams now formally engaged in the process, the FIA faces a test of how it handles a case where its own timing system produced the wrong result — and only one driver has so far benefited from the correction.
