Yeah, Kenney's lawsuit is mostly political grandstanding, but I welcome the use of the Act being challenged in court. All this makes our democracy stronger.
A law was on the books for decades but hadn't been used. It has now been used (in a rather restrained way, considering what it could be used for). This use is now being challenged in court, which will likely clarify what restrictions the use of that law actually has. Eg, did it respect the charter appropriately? Was it appropriately justified?
