Canada does have a constitution and it has amendements. The judge thus replies:

There is no doubt that Manitoba is a province.

This is something I've noticed with non-American conservatives lately - they're noticing how American conservatives have managed to bypass democracy to enact their authoritarian will, and they see the language of the loopholes they use as a kind of cheat code to override their own country's political reality. "Executive Order", "First/Second Amendment", "Presidential Power", etc.

You can see this even more clearly in the more conspiratorial fringes of conservatism like Libertarian/SovCit, where they pour over the text of laws and try to "decode" secret meanings which will let them say some magic words which allow them to be exempt from laws and open the door for authoritarian rule.

In a microcosm like this "cheat code" phenomenon, it looks as ridiculous as it is, but it's still part of a very dangerous overall trend of conservatives choosing to ignore reality and impose their own through sheer force of will.
