Russia has been ordered to pay 5.4 million euros ($6.25 million) in damages to the Netherlands for seizing the “Arctic Sunrise” Greenpeace ship and detaining its crew in 2013.

The Permanent Court of Arbitration said in an online statement on Tuesday that Russia had violated the UN Convention on the Law of the Sea by boarding the ship without consent and detaining crew members.

“Russia breached its obligations under the Convention by boarding, investigating, inspecting, arresting, detaining, and seizing the Arctic Sunrise, a vessel flying the Dutch flag, without the prior consent of the Netherlands, and by arresting, detaining, and initiating judicial proceedings against the thirty persons on board that vessel,” the court said.

The damages include compensation of 1.69 million euros for damage to the vessel and 600,000 euros “for non-material damage to the Arctic 30 for their wrongful arrest, prosecution, and detention in Russia.”
