Adrian Sutil's legal action against the Sauber F1 team has been upheld by the Supreme Court of Zurich over unpaid finances and the loss of his 2015 race seat.
Sauber covered itself in controversy in late 2014 by unveiling Marcus Ericsson and Felipe Nasr as its F1 drivers for the following season and ditching both Sutil and Giedo van der Garde.
The Dutch driver publically took his case to the Australian courts on the eve of the 2015 season-opener before the two reached a settlement by mutual consent.
Sutil, who acted as Williams' reserve driver last year, is reportedly seeking 3.5 Swiss franks (£2.4 million) in unpaid money from Sauber from 2014, while a separate case is also ongoing about unfairly losing his race seat last season.
Sauber's defence has remained steadfast by claiming the German driver failed to meet performance targets in 2014 – the Swiss team finished 10th in the constructors' championship and failed to score a single point – while also stating Sutil did not to produce $40 million worth of sponsorship as previously agreed. The case continues.
