[everforward]

That part actually seems possible, and I’m surprised it didn’t work. Last I looked, legal citations had an exacting format I would think you could parse out and check if the case exists at least. Won’t work if the AI hallucinates the citation format though, I guess.

You could maybe even verify quotes if the citation was attached (treat ellipsis as a regex “.*” and check the case text). That part would probably be imperfect, but I’d think useful at least.
