For 2002, Walkinshaw made a deal to use Cosworth V10 engines and retained Bernoldi (with support from Red Bull) but dropped Verstappen in favour of Heinz-Harald Frentzen, who became available when Prost Grand Prix closed down. This caused Verstappen successfully to sue for breach of contract. That year also saw a costly payout to Pedro Diniz after unsuccessfully suing the Brazilian, who had taken his funding to Sauber for 1999. The team faced a third litigation from Frentzen, who was contracted on a race-by-race basis and who had not yet been paid. Mounting debts including money owed to Cosworth spelled the end. Allied to sponsorship problems, Arrows ran out of money in the mid-season and did not appear at all the races at the end of the year, their drivers deliberately failing to qualify for the French Grand Prix.
