> each judge could apply his own preferred styling for working with it

imagine going to court and the judge has mandated that all documents be prepared using 18pt Jokerman[0], or that all headings must use Bleeding Cowboys[1].

I understand what you and creata are saying, and I don't necessarily disagree. What I mean is that everyone (judges and lawyers alike) could easily work off their own copy and refer to, say, paragraph numbers when necessary.

For instance, I would like 12-pt with ~1.2 line spacing, something akin to Tufte — so I have a nice wide margin to make notes and summaries.

oh, you misunderstand. this is something i want to see happen. font anarchy now!
