Shipowner Islamic Republic of Iran Shipping Lines (IRISL) has lost a bid to annul sanctions rulings made against it by the European Union in 2013.
It and 10 other linked companies had asked the Court of Justice of the European Communities to overturn a rejection of its plea to the General Court of the European Union in February 2017.
The EU had alleged in 2010 that IRISL has been involved in the shipment of military-related cargo, including proscribed cargo from Iran.
