How does a case get to the Supreme Court? A losing party in a lower court files a petition for a writ of certiorari asking the Court to review the decision; the petition must be filed within 90 days of the judgment (extendable to 150 for good cause under Rule 13), the Court receives roughly 5,000 petitions a term in its discretionary docket, and grants about 1 percent — typically 60 to 80 argued cases per term, per the Court's own statistical reports. The «rule of four» governs: four of the nine justices must vote to grant.
What is the cert pool?
Most petitions are processed through the cert pool — a shared-chambers arrangement in which one law clerk in a participating justice's chambers writes a single memo for all participating chambers, summarizing the petition and recommending grant or deny. Pool memos are famously consequential: a careless memo can bury a meritorious petition before any justice reads the underlying case. Individual justices have joined and left the pool over the years; the practice, not any rule, defines the Court's triage.
What makes a petition grantable?
Supreme Court Rule 10 states the Court's own criteria — not entitlement, but «compelling reasons»: a federal circuit conflict (a «circuit split») on an important question; a state supreme court or federal court decision conflicting with other courts on federal law; or a decision so far departing from accepted judicial process that supervisory intervention is warranted. Practitioners add the unwritten screens: the question's national importance, the vehicle's cleanliness (no weak standing, no disputed facts, no procedural wrinkles that invite dismissal as improvidently granted), and recency — the Court grants fresh conflicts more readily than stale ones.
What are the procedural stops along the way?
- Filing: petition, plus the lower courts' opinions, formatted per the Court's rules and e-filed through its case-management system.
- Response: the other side may waive or file a brief in opposition; the Court can call for a response, and can invite the Solicitor General's views («CVSG») before deciding.
- Distribution and conference: petitions are distributed to chambers and voted at weekly conferences during the term; grants are announced in orders lists, usually Monday mornings.
- Briefing and argument: if granted, briefing runs months, argument is scheduled, and decisions issue by term's end — the Court aims to sit from October to late June or early July.
What is a GVR?
Grant, vacate, remand: a frequent compromise disposition in which the Court grants cert, wipes the lower court's judgment, and sends the case back for reconsideration in light of a newly decided case or changed law — no argument, no full opinion. Election-law watchers saw repeated GVRs after major voting-rights rulings, as lower courts reworked map and ballot disputes under new precedents.
What are a justice's options on a denial?
Denial is not a merits ruling: it establishes no precedent, and the lower decision simply stands. Individual justices may write a statement «respecting denial» — increasingly common in recent terms to flag questions the Court is not yet taking — or dissent from denial, sometimes signaling where a future majority might be heading. Reading denials is a parlor game with real odds: recurring dissents from denial often preview next term's grants.
FAQ
What is the rule of four?
The unwritten practice that four justices' votes suffice to grant certiorari — a check ensuring the Court's docket is not controlled by a bare majority.
Can you appeal as of right?
Almost never: the Court's mandatory jurisdiction was essentially eliminated in 1988, leaving a few narrow categories like original-jurisdiction disputes between states.
How long does the whole process take?
From judgment to argument is typically 12 to 18 months for a granted case; the petition itself may sit for months before the grant-or-deny vote.
