A group of judges from Brazil's Regional Federal Tribunal (TRF1) suspended construction of the Belo Monte dam project on the Amazon's Xingu River Aug. 14, finding that indigenous people had not been properly consulted prior to approval of the project. The ruling upheld an earlier decision that declared the Brazilian Congress' authorization of the project in 2005 to be unconstitutional. The decision finds that the Brazilian constitution and ILO Convention 169, to which Brazil is party, require that Congress can only authorize the use of water resources for hydroelectric projects after an independent assessment of environmental impacts and subsequent consultations with affected indigenous peoples.
