Seven teams are considering legal actions against the FIA because of the way it handled the Ferrari fuel flow investigation.

One team who are pondering the possibility of suing the sport’s governing body for the prize money it missed out on in 2019 is Red Bull, with their advisor Helmut Marko not impressed with how the saga was handled.

In the aftermath of the summer break last season, Ferrari recorded three successive victories, along with five successive poles, in a remarkable revival that saw them close the gap to Mercedes and pull away from Marko's Red Bull.

But, following requests from the Austrian-based team, the FIA issued a number of technical motives relating to fuel flow.

In the weeks that followed, the threat from the Italian driving team dropped significantly as Lewis Hamilton and Valtteri Bottas drove away with the Drivers' Championship (Hamilton), and the Constructors' Championship.

As pre-season testing came to an end on Friday, the FIA compiled a statement that further clouded this issue, giving away no details of what its investigation prolonged. The statement issued into the Ferrari engine effectively concluded to the world that there was nothing to see.

That is not the case to other driving teams, however, as seven rivals believe the opposite where there is something to see and also refuse to move along. The teams have threatened legal action with the FIA following the action they have taken and its total lack of transparency.

Red Bull lost out most during Ferrari’s short-lived revival and they believe it has lost out twice, not only on the track, but in terms of prize money also.

"We lose a double-digit million amount by finishing third instead of second," Helmut Marko told Auto Motor und Sport, as per PitPass.

"Not just because more money is distributed for second place, but because our sponsorship contracts are also performance-related. I assume that the other teams are similar.

"We have to assume we would have beaten them on the track if everything was fine with the engine," he added.

With an eye on the Spygate cheating scandal that saw McLaren fined $100m in 2007, Marko believes that the Italian team should be similarly punished to conclude fairness.

"If they really cheated, 10 or 20 million would be far too cheap," he said.

"The behaviour of the FIA is the real scandal," he told Der Spiegel in a separate interview.

"We should actually instruct Christian (Horner) to sue for $24 million in prize money."
