"Counsel, I'm unfamiliar with the case you've cited. Have you brought a copy for the court? No? How about a bench brief? Very well. I am going to excuse the panel for lunch and place the court in recess. Members of the jury, please return at 1:00. Counsel, please arrive with bench briefs including printouts of major cases at 12:30. Court stands in recess." bang

"All rise!"

IANAL, but I'd think in this case this is prosecutor's job.

Also, the original post is about the traffic ticket. I'm pretty sure if the judge hears a reference to something he had never heard before, he'll be like "huh? wtf?"

That’s not how the legal system works. You aren’t slipping anything through. Either the judge knows the case, they don’t know all the cases, or the judge will research or clerks will research and you will be sanctioned if you try to do so thing unethical.
