Since 2008 increasing pirate activities in Somalia, the Gulf of Aden, and the Indian Ocean have once again drawn the international community's attention to piracy and armed robbery at sea. States are resolved to repress these impediments to the free flow of trade and navigation. To this end a number of multinational counter-piracy missions have been deployed to the region.

This book describes the enforcement powers that States may rely upon in their quest to repress piracy in the larger Gulf of Aden region. The piracy rules of the United Nations Convention on the Law of the Sea (UNCLOS) and the legal safeguards applicable to maritime interception operations are scrutinized before the analysis turns to the criminal prosecution of pirates and armed robbers at sea. The discussion includes so-called shiprider agreements, the transfers of alleged offenders to regional states, the jurisdictional bases for prosecuting pirates, and the feasibility of an internationalized venue for their trial. In addressing a range of relevant issues, this book presents a detailed and comprehensive up-to-date analysis of the legal issues pertaining to the repression of piracy and armed robbery at sea and assesses whether the currently existing legal regime is still adequate to effectively counter piracy in the 21st century.
