> The Parliament of Canada, a provincial legislature or a territorial legislature may declare that one of its laws or part of a law applies temporarily ("notwithstanding") countermanding sections of the Charter, thereby nullifying any judicial review by overriding the Charter protections for a limited period of time. This is done by including a section in the law clearly specifying which rights have been overridden. A simple majority vote in any of Canada's 14 jurisdictions may suspend the core rights of the Charter.
Basically, imagine if states could pass temporary laws that were not allowed to be challenged as unconstitutional. For some reason, Canada allows that.
