of the oil pipeline means that there is a higher risk of an oil spill into Lake Oahe, which made the tribe concerned. The Sioux Tribe sued the DAPL company as they believed that the creation of the pipeline was violating the National Environmental Policy Act and the National Historic Preservation Act. After the 2016 briefing, the court was unable to come to a conclusion, so the court decided to do additional briefings. After 5 briefings in 2017 and 1 briefing in 2018, the court has allowed the construction of the pipeline, but the Standing Rock tribe continues to fight to ensure that pipeline is removed. Australia The attention in Australia is focused on the rights of Indigenous Australians to water and sanitation. History of settler-colonialism overshadows today's state governance that regulates water use to indigenous Australians. There are many governmental agreements, but most of them are incomplete to fully influence power to the indigenous right to water and sanitation. In Mabo v Queensland, 1992, Native rights were legally recognized at the first time. Indigenous Australians often claim cultural bonds to the land. Although "culture" was recognized in the court as much as land resources, cultural and spiritual value of Aborigines to water body are fuzzy. It is challenging but needed to transcend their cultural and spiritual values into legal sphere. For now, there is virtually no progress. Australian water law basically prescribes surface water for citizens who can use surface water but cannot own. In the constitution, however, there is no description about inland and riparian water. Therefore, the sphere of inland/riparian water rights are the primary mandates of the state. The Commonwealth Government obtains authority over water by borrowing the help of external relationship, including the Grants Power, Trade and Commerce Power. In 2000, the Federal Court concluded the agreement that allowed indigenous landowners to take water for traditional purposes. However, the use is limited to traditional purpose, which did not include irrigation as a traditional practice. In June 2004, CoAC concluded an intergovernmental accord on a National Water Initiative (NWI), promoting recognition of indigenous right to water. However, NWI is not concerned broadly about complex history of settler-colonialism, which has systematically created an unequal pattern of water distribution. Indigenous people in Australia are constantly seeking the right to water. Remaining discussions Transboundary effects Given the fact that access to water is a cross-border source of concern and
