Follow those rules, and your pleadings are accepted and filed. Violate those rules, and your pleadings are rejected. I recall one instance when some hot shot lawyers filed an amicus curia brief on behalf of the American Bar Association itself. But they were one day late.
The Clerk rejected their pleading. And when they had the effrontery to file a motion that their brief be accepted anyway, the motion was summarily rejected, without dissent or comment.
Anyone can read the Rules on line. However, the best practice is to associate with a veteran printer who has done hundreds of these briefs, and follow their advice. That's what I have done over the decades.

I suspect I will be filing a petition for a Writ of Cert with the USSC in February. How does one go about finding one of these printers?
Never mind; I googled it.
