Sweden's Stena Group is hoping to overturn a Danish court verdict in a row dating back to the sale of a seized tanker cargo in 2013.
The Stena Oil unit has lodged an appeal to the Supreme Court in a bid to win a $6.5m compensation battle with Danish bunker and tanker group Monjasa.
Monjasa bought 10,000 tonnes of Stena's oil confiscated by the government of Sao Tome and Principe, following what the African nation said was an illegal transfer between two Stena-chartered tankers.
