F1: Former Sauber driver Adrian Sutil in legal battle with team

Williams reserve driver Adrian Sutil's ongoing legal battle with Sauber has taken another step after a recent judgement by the Supreme Court in Zurich.

Sutil drove for the Swiss outfit in 2014 and had a contract that extended into a second season. However, the team opted to take Marcus Ericsson and Felipe Nasr for 2015, a move that led to a legal fight with Giedo van der Garde -“ who also had a contract with the Swiss team. That came to a head in Melbourne, which resulted in a victory for the Dutchman.

Sutil had launched his own legal action, and it has been proceeding quietly since early last year. The current case relates to unpaid monies from the 2014 season, and involves well over $3.5 million.

Meanwhile, there is also separate action in progress against Sauber involving the fact that Sutil did not race in 2015.

In its submissions, Sauber argued that Sutil had underperformed and had been critical of the team, also claiming he guaranteed to help find $40 million in sponsorship - and extraordinary figure and one that Sutil denies.

However, the judge took Sutil's side and has allowed the case to proceed.
