The funds were paid by Uralkali to the team before the start of the season.

Haas is also seeking an additional $8.6 million in compensation for "lost profits," according to Motorsport.

“According to the unanimous opinion of legal scholars and case law, a party who terminates a contract because of a breach by the other party is not required to return to that party what it has already received under the contract,” Haas said in a statement.

Recall that in March, the Haas team terminated the contract with Uralkali and the Russian pilot of the team, Russian Nikita Mazepin.

Earlier, Nikita Mazepin told what kind of assistance his foundation would provide to suspended athletes.
