Arguments are over in a Regina courtroom, and now the decision on the future of a federally imposed carbon tax is in the hands of the Saskatchewan Court of Appeals.

The judges heard arguments from the provincial government and concerned parties intervening on their behalf on Wednesday, and Thursday it was the chance for the federal government to present their case.

The province is challenging the carbon tax on grounds it is unconstitutional.

“We think the proper position for our province to take is not to have a carbon tax that singles out our province,” said Saskatchewan Justice Minister Don Morgan. “We think the right thing to do would be to sit down and work with all of the provinces and develop good alternatives to reduce carbon emissions.”

The judges hearing the case have reserved their decision. Many are hoping they deliver the decision by April when the carbon tax would take effect. However, it could take up to six months or a year before the decision is finalized.
