The problem as I see it is that there is a public policy issue involved in that the copyright owners are in essence controlling access to the law, even though the law affects everyone. Obviously, this is not nearly as troubling as what West has been trying to do, but it still is worrisome. In other words, I would think that copyright law should be that any time copyright expression becomes enacted into law, that it is automatically fair use to reproduce, etc. that expression in the context of that law.
Copying is the act of taking a specific copy and replicating it.
I do not think that there is any doubt as to who owned the copyright in the work. In other words, the legislature was not the author of the work. The preceding was not a legal opinion, and is not my employer's.
