Last December, Cajamarca’s regional government declared Conga to be ‘unviable’, citing concerns over the conservation of the region’s water supply, and sustainable development.

Tuesday’s ruling said Cajamarca’s government had exceeded its legislative powers, and said the region had no jurisdiction over regulations affecting medium and large mining projects, such as Conga.

The court also said the National Water Authority was the sole government agency that could rule on the viability of projects that involve the country’s water, Peruthisweek.com reported.

Earlier this year the government ordered a reassessment of Conga’s environmental impact study, after protests by nearby communities who expressed concern the mine would affect local water supplies.

The new Conga environmental impact study will be presented at 5pm, on Tuesday afternoon.
