Now, a year later, that battle — pitting several provinces against the federal government — will play out over two days in a Regina courtroom as the province's Court of Appeal hears arguments Wednesday and Thursday on Saskatchewan's constitutional challenge of the carbon tax. That may not matter to the provincial government itself, or to the governments in Ontario and New Brunswick that are backing Saskatchewan's court play. Saskatchewan's justice minister makes no secret of the fact that the constitutional challenge is at least partly about sending a message to voters. Odds are, however, that this constitutional challenge will end up in front of the Supreme Court of Canada. Assuming nothing else changes, the carbon pricing plan will be back before the courts in April, when a court challenge instigated by the province of Ontario begins.
