This is perhaps a good time to point out a case where my access to law was blocked by a walled garden. Not too long ago I was looking at
NC law § 115C-402.5 (b)(2), where it delegates legislation to the NC board of education. Yet when I go to
the site with those laws, I find a paywall. As far as I can tell, the public does not get access to that law.
BTW, when I previously said "the law itself is also in a walled-garden", I did not mean
all copies of the law are in a walled garden. I meant that the up-to-date Lexis copy of law is in a walled garden, and we incidentally benefit from the existence of other copies being published online. But if those other copies were not available online, then Lexis would in fact be a private company who controls the sole copy law published online. It's a bit haphazard how that's working out, and there are holes in it when you look at the case of North Carolina BoE.
And FWIW, I've been to a law library before looking for the book that covers the law on how to format a civil complaint in Ohio. I probably spent upwards of 30 min. looking for a book on civil procedure that would cover that and could not find it. There was no catalog as far as I could see, and the legal jargon on the binders is hard to understand for a non-lawyer.
