Through International law, Piracy and United Nations

Piracy threatens maritime security and the legitimate uses of the seas for peaceful purposes and the freedom of navigation (freedom of the seas, Mare Liberum). All ships and countries are free to trade and navigate the oceans, a right which is threatened by piracy. A 2008 report by the International Maritime Organization found 4,821 incidents of modern piracy and maritime armed robbery in the period 1984 to 2008. In these incidents, 6 crew were killed, 42 assaulted, 774 held hostage and 38 crew are unaccounted for.

Piracy law as codified in UNCLOS

UNCLOS codified the laws of piracy in Articles 100 to 110. Article 108 is not strictly piracy law, but for the suppression of illicit traffic of narcotic drugs at sea. The Max Planck Encyclopedia of International Law argues that article 109 on pirate broadcasting by radio transmission is now an out-dated grandfather clause, given the liberalisation of broadcasting licence systems. However, it argues the clause may still be relevant in allowing states to prevent hostile propaganda broadcasts. The piracy articles of UNCLOS replicate Articles 14 to 21 of the 1958 Geneva Convention on the High Seas. It has been ratified by 168 states and there are 157 signatories (accepted but not signed). The treaty is accepted as customary international law.

The flag state normally has jurisdiction and responsibility for a vessel on the high seas. The term hostis humani generis (enemy of all mankind) was applied to pirates in the 1927 Lotus case of the Permanent Court of International Justice, the League of Nations equivalent of the International Court of Justice. As such, there is universal jurisdiction over piracy on the high seas. Pirates are denied protection of the flag state and all states have the right to seize a pirate ship on the high seas and to prosecute in national courts.
