alt Hacker NewsIt's the difference OP is referring to. You can be the judge of if it's relevant in the US to talk about civil law as the "norm" given that our legal system is not, in fact, based on civil law. I'm just providing a link to the concepts OP was referencing.
I don't think it is, because textualism is just one school (the other current school is legal realism) in the US system, which is common law. But I'm not sniping you, I'm just pursuing a nerdy angle here.
