Greenpeace International activist Ana Paula Alminhana Maciel from Brazil, one of the "Arctic 30" detained on piracy charges, attends her bail hearing at the Regional Court of Murmansk Oct. 24, 2013 in this handout from Greenpeace.

Russia was a "no-show" at a hearing with the International Tribunal for the Law of the Sea regarding the Dutch bid to force the immediate release of the detained Greenpeace activists, as well as the release of their ship, the Arctic Sunrise.

Liesbeth Lijnzaad, a representative for the Netherlands, urged the court to go ahead with the proceedings despite Russia not being in attendance. The 30 detainees, also known as the Arctic 30, are being charged with hooliganism for their Sept. 18 protest in which they tried to climb on to Russia's offshore Arctic oil rig.

Russia has said it does not accept the arbitration procedure and will not participate in the proceedings.
