Four tribes have gone to federal court at Pierre in an effort to stop construction of the Keystone oil pipeline through eastern South Dakota and North Dakota.
The tribes argue that treaties, as well as federal laws and regulations, were broken during the environmental assessment of the route and subsequent granting of a presidential permit for the pipeline.
