CTV News: 'Alberta Premier Jason Kenney says the province will be challenging the federal government's use of the Emergencies Act in court.
'On Saturday, the premier said that invoking the Act violates "natural justice" and is "unnecessary."
'"The federal government's invocation of the Emergencies Act is an unnecessary and disproportionate measure that can violate civil liberties, invades provincial jurisdiction, and creates a very dangerous precedent for the future," Kenney said in a video posted to social media.
'"It's not necessary," he added. "Provincial law enforcement agencies are able to deal with illegal road blockades.'
