All of these flag States have the right to sail ships flying their flag on the high seas (LOSC Article 90) ; and those ships enjo y the freedom of navigation upon the high seas (LOSC Article 87) . W ith this freedom comes a concomitant duty upon the flag State to effectively exercise its jurisdiction and control in administrative , technical , social (LOSC Article 94 (1)) and en vironmental protection (LOSC Article 217) matters over ships flying its flag. 1.2 Flag State Responsibility The absence of any authority over ships sailing the high seas would lead to chaos.
