Here's a breakdown: Initial Filing (Rule 21): The standard requirement for extraordinary writs, including mandamus in the Circuit Courts (which feed into the Supreme Court), is an original plus 3 copies. Circuit Court: You file with the Circuit Clerk and serve parties/judge, following Rule 21 for the initial petition (original + 3 copies). U.S. Supreme Court (If it reaches them): While Rule 21 governs the Circuit Courts, the Supreme Court's own rules for certiorari petitions (which Mandamus often relates to) usually demand 40 copies for paid cases during briefing stages, but this varies.
