UNCLOS has already been used as a backdoor mechanism to change environmental policies of member nations
Nations have already attempted to use the Law of the Sea Treaty's environmental provisions to affect the environmental policies of others. In 1999, Australia and New Zealand appealed to the International Tribunal of the Law of the Sea (ITLOS) to shut down Japan's experimental southern blue fin tuna fishing program, citing Articles 64 and 116-119. Although the Tribunal ultimately decided that it lacked jurisdiction in the case, Australia and New Zealand did gain a temporary injunction on the program.36 More recently, Ireland sought ITLOS's help in forcing the United Kingdom to abandon its planned opening of the Sellafield MOX plant, a nuclear fuel reprocessing plant in northern eastern England, arguing that it would contribute to pollution of the North Sea. Although ITLOS did not rule in Ireland's favor, it ordered both Ireland and the United Kingdom to enter into consultations.37

UNCLOS has a number of provisions requiring state parties to do all they can to protect the environment that could be used by environmental groups to force regulations and treaties on to the U.S.
