U.S. SUPREME COURT

The U.S. Supreme Court can review state court decisions ONLY if they involve a federal constitutional or statutory question. The case must have gone through the state's highest court (or the highest court with jurisdiction). Review is via petition for writ of certiorari under 28 U.S.C. § 1257. The Court grants cert in fewer than 2% of petitions.

The California Supreme Court is the highest court in the California state court system. It reviews Court of Appeal decisions via 'petition for review' (CRC 8.500). The U.S. Supreme Court is the highest court in the federal judiciary. It reviews federal circuit court and state supreme court decisions involving federal questions via 'petition for certiorari' (28 U.S.C. § 1257). These are entirely separate systems with different rules, forms, and deadlines.

Prepare a petition following Supreme Court Rule 14 (content) and Rule 33 (format). Paid petitions: $300 fee + 40 booklet copies. IFP petitions: sworn affidavit of indigency + 1 unbound copy, no fee. File within 90 days of the lower court's judgment. Bar members e-file; pro se litigants mail paper copies.

File a sworn affidavit or declaration demonstrating that you cannot afford the $300 docket fee and the cost of printing the petition in booklet format. IFP petitions need only 1 unbound copy (not booklet format). No filing fee is required. Governed by Supreme Court Rule 39.

File a Brief in Opposition within 30 days of receiving the petition (Supreme Court Rule 15). The brief should explain why certiorari should not be granted. You may waive your right to respond by filing a letter with the Clerk — the Court will then not call for a response unless interested.

In California, declarations (under penalty of perjury) are used instead of affidavits (sworn before a notary). Both are statements of fact. Cal. Civ. Proc. Code § 2015.5 allows declarations to substitute for affidavits. In federal court, either may be used. In the U.S. Supreme Court, 28 U.S.C. § 1746 allows declarations.

Declarations under 28 U.S.C. § 1746 are accepted. For IFP petitions, the affidavit or declaration of indigency must be sworn. Follow the Supreme Court Rules for format requirements.

File a petition in forma pauperis (IFP) under Supreme Court Rule 39. Submit a sworn affidavit or declaration of indigency. You are exempt from the $300 docket fee and booklet-format printing requirements. File 1 unbound copy of the petition by mail.

Serve copies of the petition on all counsel of record (or pro se parties) for all respondents. For paid petitions: serve 3 copies. For IFP petitions: serve 1 copy. Service may be by mail or commercial carrier. File proof of service with the petition.

A petition for writ of certiorari asks the U.S. Supreme Court to review a decision of a federal circuit court or a state supreme court on a federal question. The Court exercises discretionary jurisdiction — it chooses which cases to hear. Filed within 90 days of the lower court's judgment. Supreme Court Rule 13.

Very low. The Supreme Court receives approximately 7,000+ petitions per year and grants certiorari in roughly 70–80 cases (about 1–2%). Cases with circuit splits, important federal questions, or significant constitutional issues have the best chance.

Courts apply different standards depending on what is being reviewed: (1) De novo — legal questions (no deference to trial court), (2) Substantial evidence — factual findings (upheld if any reasonable evidence supports them), (3) Abuse of discretion — discretionary rulings (upheld unless clearly wrong). Identify the standard in your briefing.

The Court of Appeal's decision becomes final. Your options: (1) If a federal question is involved, you may petition the U.S. Supreme Court for certiorari within 90 days. (2) If no federal question, the case is generally over. Denial of review is NOT a ruling on the merits.

An amicus curiae ('friend of the court') brief is filed by a non-party who has an interest in the case's outcome. At the U.S. Supreme Court: governed by Rule 37 (blanket consent at merits stage; motion needed at cert stage). In California: governed by CRC 8.200(c). Amicus briefs can help the court understand broader implications.

Oral argument is a live presentation before the appellate judges. In California Courts of Appeal, either party can request it; the court may also calendar it sua sponte. At the U.S. Supreme Court, oral argument is granted in all cases where cert is granted. It is typically 30 minutes per side at SCOTUS.

A writ of habeas corpus challenges the legality of a person's detention or imprisonment. It can be filed in Superior Court, Court of Appeal, California Supreme Court, or federal court (28 U.S.C. § 2254). It is NOT a direct appeal — it raises claims that could not have been raised on direct appeal (e.g., ineffective assistance of counsel, newly discovered evidence).

Only members of the Supreme Court Bar can e-file. Pro se litigants must file paper copies by mail. IFP petitioners file 1 unbound copy by mail. The e-filing system is at the Supreme Court's electronic filing page.

For California state courts: Pacific Time. A document e-filed by 11:59 PM Pacific Time on the deadline day is timely. For the U.S. Supreme Court: Eastern Time. Check the specific court's rules for after-hours filing acceptance.

The Supreme Court operates under the Supreme Court Rules (not 'local rules'). These are the Court's own comprehensive procedural rules, effective March 16, 2026. They govern all filings, briefing, oral argument, and Court procedures.

Filing frivolous petitions. The Supreme Court grants cert in fewer than 2% of cases. Filing without a genuine circuit split or important federal question wastes resources. Other common mistakes: missing the 90-day deadline, incorrect formatting, failing to follow Rule 14 content requirements, and not serving opposing parties.

9,000 words for a paid petition (Rule 33.1(g)(i)). IFP petitions follow the same content requirements (Rule 14) but are not subject to booklet-format rules. The Brief in Opposition has the same 9,000-word limit. Reply brief: 3,000 words.

File an Application for Admission to the Bar of the Supreme Court. Requirements: (1) admitted to practice in the highest court of a state for 3+ years, (2) currently in good standing, (3) sponsored by 2 members of the Supreme Court Bar who attest to your qualifications. Fee: $200. Admission can be done by mail or in open court.

Petition for review: asks the California Supreme Court to review a California Court of Appeal decision. Governed by Cal. Rules of Court, rule 8.500. 10-day deadline. Petition for certiorari: asks the U.S. Supreme Court to review a federal circuit court or state supreme court decision on federal questions. Governed by Supreme Court Rule 13. 90-day deadline. Different courts, different rules, different standards.

Supreme Court Rule 10 lists the 'considerations governing review on certiorari': (a) conflict among federal circuits on an important federal question, (b) a state court or federal court has decided an important federal question in a way that conflicts with decisions of other courts, (c) a state court or federal court has so far departed from the accepted and usual course of judicial proceedings as to call for the Court's supervisory power. Rule 10 notes that certiorari 'is not a matter of right, but of judicial discretion.'

Supreme Court Rule 33: 6⅛ × 9¼ inch booklet format. Cover colors: cert petition (white), brief in opposition (orange), reply brief (yellow), merits brief for petitioner (light blue), merits brief for respondent (light red), amicus (light green), joint appendix (tan). Century family typeface, 12-point.

Younger v. Harris (1971): federal courts must abstain from enjoining ongoing state criminal proceedings (and certain civil proceedings) absent extraordinary circumstances. Based on comity and federalism. Exceptions: bad faith prosecution, patently unconstitutional statute, or other extraordinary circumstances. Key for federal court practitioners.

Qualified immunity shields government officials from civil liability unless their conduct violates 'clearly established' constitutional rights. Two-part test: (1) did the official violate a constitutional right? (2) was the right 'clearly established' at the time? The Supreme Court has developed this doctrine extensively. Key cases: Harlow v. Fitzgerald (1982), Pearson v. Callahan (2009).

The U.S. Supreme Court will not review a state court decision that rests on an independent and adequate state-law ground, even if the decision also involves federal questions. The state ground must be both genuinely independent (not intertwined with federal law) and adequate (regularly followed). Michigan v. Long (1983): if the state court's reliance on state law is ambiguous, SCOTUS assumes jurisdiction.

Article III standing requires: (1) injury in fact (concrete, particularized, actual or imminent), (2) causation (fairly traceable to defendant's conduct), (3) redressability (likely to be redressed by a favorable decision). Key cases: Lujan v. Defenders of Wildlife (1992), TransUnion v. Ramirez (2021). Standing is jurisdictional and can be raised at any time.

Erie Railroad Co. v. Tompkins (1938): In diversity cases, federal courts apply state substantive law and federal procedural law. Determines which law governs in federal court when hearing state-law claims. Key follow-up: Hanna v. Plumer (1965), Shady Grove v. Allstate (2010).

The 'rule of four' is the Supreme Court's internal practice requiring four of the nine Justices to agree before certiorari is granted. This is a custom, not a rule of law. It means a minority of the Court can force full briefing and argument on a case.
