An indigenous group seeks to halt an agreement to ship LNG out of western Canada, according to a recently filed petition.

The Blueberry River First Nations filed a supreme court petition last week against British Columbia’s Minister of Natural Gas Development to halt the latter’s approval of the Pacific NorthWest LNG project.

The CAD 11bn ($8.3bn) project, backed by a consortium led by Malaysian national oil company Petronas, aims to initially ship 12 million tonnes per annum of LNG produced from the nearby North Montney Shale formation.
