Oil and Gas New case (filed in past two years): http://canadians.org/blog/?p=19087#more-19087
– Lone Pine Resources vs. Canada: A U.S.-backed energy firm with headquarters in Calgary is challenging Quebecs ban on oil and gas exploration in the St. Lawrence Valley, claiming $250 million in damages in breach of NAFTAs fair and equitable treatment and expropriation clauses. The recently elected Parti Québécois government had campaigned on a promise to put a stop to hydraulic fracturing in the region – a promise that had broad public support. But the company claims the decision was arbitrary, and the law firm representing them says the fracking ban is exactly what the NAFTA rights are supposed to be protecting investors against.
