Yes, it should absolutely change (both should be freely available), since ignorance of the law is not a defense, and case law is law (here, in the US, since we're a common law country). But the flip side of that is that the law has to be knowable, if ignorance is not a defense, or you're just going "lol too bad for you for not knowing the secret law".

Also, because how the judicial branch decides case law needs to be reviewable by the People, so that we can inform the various legislatures to adjust the law if the judicial system is not ruling to the will of the People.
