In 2008, the FAS service imposed fines on all key Russian oil companies for price fixing totalling about $50m per company. Oil companies, however, won court rulings overturning the decisions, wrote Reuters.
In 2009, the service ruled that Lukoil and Rosneft breached anti-trust legislation and imposed more than $300m in combined fines against their peers, Gazprom Neft and TNK-BP.
Both companies said that they would appeal the rulings and it is not known whether they have paid the fines.
Russia recently sanctioned a legislation package that increases FAS’s powers.
