Adopting resolution 1897 (2009) unanimously and acting under Chapter VII of the United Nations Charter, the Council also invited all States and regional organizations engaged in this fight to conclude special agreements or arrangements with countries willing to take custody of pirates. Those arrangements should allow for the embarkation of law enforcement officials—or “shipriders”—from these willing countries to facilitate the investigation and prosecution of persons detained as a result of anti-piracy operations, provided that the advance consent of the TFG was obtained for third State jurisdiction in Somali territorial waters and that such arrangements did not prejudice the effective implementation of the 1988 Convention for the Suppression of Unlawful Acts against the Safety of Maritime Navigation.
