The provincial government has filed notice that they will be appealing the carbon tax decision to the Supreme Court of Canada.

The province is asking the court if the Greenhouse Gas Pollution Pricing Act implemented by the federal government is constitutional.

The province is also asking if Parliament has the jurisdiction to establish minimum standards for price stringency under the Constitution Act of 1867.

Provincial Justice Minister Don Morgan said their constitutional law branch filed the notice of appeal to take their case to the highest court in the nation. 

"Even though we weren't successful at the Saskatchewan Court of Appeal, the dissenting opinions were pretty clear," Morgan said at a media scrum Friday. "They reflected the arguments that were put forward by the province. I'm hopeful that that carries the day as we go into the Supreme Court. I'm also pleased to see that a number of other provincial jurisdictions have come onboard, and applying for intervenor status and are going forward. It's a shift."

Morgan is hopeful the case will be heard in the fall. 

"We've got two months in which to file our factum, but the Supreme Court will allow other people that are intervenors additional time to file their material," he said. "I'm not optimistic that it's going to be heard anytime within that two month period, but hopefully something this fall."

There is now a two-month window for the provincial government to file a factum to the Supreme Court.
