Hmmmmmm.

I’ve signed up for Studicata in the past and just watched/studied what was there. It’s intended for law school students, but at least when I last signed up, it wasn’t restricted or anything. It’s super interesting and informative on the theory of law, and I’d definitely recommend the content on there, but your example specifically sounds more like a “court procedure” thing that… probably wouldn’t be covered I wouldn’t think?

I’ve also read this text book specifically about intellectual property law, but that seems even further off the mark of what you’re looking for.

Probably the ultimate right answer to your question is “law school”, but given that you’re asking here in Lemmy, I doubt that’s the answer you’re looking for.

Edit: Ooo. Maybe the references on the Wikipedia page about “Sidebar” might answer your main question there.
