The Supreme Court of Zurich has upheld a legal action taken by Adrian Sutil against former team Sauber over unpaid monies and the loss of his 2015 race seat.
Sauber's decision to hire Marcus Ericsson and Felipe Nasr in late 2014 for the following season set it directly against Sutil and Giedo van der Garde. The latter took his complaint to court on the eve of the 2015 Australian Grand Prix in a splash of publicity, with the two parties eventually reaching a settlement by mutual consent.
Sutil's own legal action has been growing quietly since last year and the Williams reserve driver is seeking compensation 3.5 million Swiss franks (£2.4 million) in unpaid money from 2014. A separate action in progress is about the fact Sutil did not race for the team in 2015.
Sauber's submissions stated Sutil had underperformed and been critical of the team, as well as failing to find $40m of sponsorship despite promising to do so. However, a judge at the Supreme Court has allowed the case to continue.
