A landmark criminal resolution involving a Greek-based shipping company’s transport of nearly 1 million barrels of contraband crude oil from Iran was unsealed by the Department of Justice (DOJ).

Empire Navigation, operator of the Suez Rajan Limited vessel, pleaded guilty in April to violating the International Emergency Economic Powers Act by carrying the crude oil from the sanctioned Islamic Revolutionary Guard Corps (IRGC) to another country, the DOJ announced in a press release Friday. Empire was sentenced to pay a nearly $2.5 million fine in addition to three years of corporate probation as part of a deferred prosecution agreement.
