Red Bull have joined McLaren by lodging a notification to appeal with the FIA's International Court of Appeal over the decision to rescind Pierre Gasly's speeding penalties at the Monaco Grand Prix and reinstate the Alpine driver on the podium, sources have told ESPN.
In a review hearing on Friday, the Monaco Grand Prix stewards overturned two five-second post-race penalties issued to Gasly after Formula One Management (FOM) admitted it had made an error in measuring the speeds of cars at the pit lane entrance.
Gasly had dropped from third to seventh before the penalty was overturned -- the decision meant Red Bull's Isack Hadjar was bumped off the podium -- his first for the team -- to fourth.
Gasly was among five drivers who received penalties for speeding in the pit lane during the grand prix, including McLaren's Oscar Piastri, who received a five-second penalty for breaking the speed limit by 0.1km/h.
Piastri also lost a position when Gasly was reinstated, dropping from fourth to fifth once the Alpine driver's penalty was overturned.
On Tuesday, McLaren confirmed it was pressing ahead with its intention to appeal the revised result on the basis that teams were aware of the discrepancies in the pit lane measurements and adjusted its procedures in order to comply.
A Red Bull spokesperson confirmed to ESPN it is also following up with its intention to appeal, although it has not put out anything officially.
"While we fully respect the FIA's judicial processes and the role of the stewards, we believe this case raises important questions concerning sporting fairness, regulatory consistency and the integrity of competition," a McLaren team statement said.
"Throughout the Monaco Grand Prix weekend -- and in every event -- all teams operated according to the regulations and established standard practices for what concerns the speed limit in the pit lane as they were applied at the time. Competitors adjusted their procedures accordingly and, where required, accepted and served penalties imposed under those regulations.
"In our view, the subsequent removal of penalties creates a situation in which some competitors are disadvantaged by having acted in accordance with the rules and the stewards' decisions. Such an outcome risks creating sporting inequity and undermining confidence in the consistent application of the FIA Sporting Regulations.
"Our decision to appeal is not directed at any competitor. Rather, it reflects our belief that the championship benefits from regulations that are applied consistently, transparently and fairly to all participants. "McLaren remains committed to working constructively with the FIA, Formula One and fellow competitors to protect the integrity of the sport and maintain confidence in its regulatory framework."
Piastri, Lewis Hamilton and George Russell all served pit lane speeding penalties during the race, which meant the penalties were not possible to overturn.
Alpine was the only team to launch a right to review after the race and was successful in overturning Gasly's penalties by providing new evidence to the stewards, which included FOM's admission it had miscalculated the length between two timing loops at the pit lane entry.

Meanwhile, Mercedes has spoken with lawyers about its position, which arguably cost Russell a shot at the podium.
"We've asked for a right of review, because you just simply want to sit on the table when decisions are being made," Mercedes boss Toto Wolff said. "[But] I still think it's a long shot."
