A circuit court is a court with authority over a defined geographic territory, but the definition of a circuit court depends entirely on which court system you’re asking about. In the federal judiciary, circuit courts are the thirteen intermediate appellate courts that review decisions made by trial-level district courts. In many state systems, a circuit court is the opposite: a trial court where cases begin, with juries, witnesses, and original judgments. Confusing the two is easy, and doing so can send a filing to the wrong courthouse or blow a critical deadline.
Federal Circuit Courts of Appeals
The federal court system has thirteen circuit courts of appeals, established under 28 U.S.C. § 41.1Office of the Law Revision Counsel. 28 USC 41 – Number and Composition of Circuits Twelve are regional. The First Circuit covers parts of New England; the Ninth Circuit spans much of the western United States and the Pacific territories.2United States Courts for the Ninth Circuit. What Is the Ninth Circuit The thirteenth, called the Federal Circuit, handles certain specialized subject areas nationwide rather than a geographic region.
Their job is to review decisions of the lower federal district courts. Under 28 U.S.C. § 1291, the courts of appeals have jurisdiction over all final decisions from the district courts.3Office of the Law Revision Counsel. 28 USC 1291 – Final Decisions of District Courts An appeal is not a new trial. No witnesses testify, no jury is selected, and no new evidence comes in. A panel of judges examines the record from below and decides whether the trial court got the law right.4United States Courts.

Each circuit has a set number of authorized judgeships. The Ninth Circuit has the most at 29; the First has as few as six.5Office of the Law Revision Counsel. 28 USC 44 – Appointment, Tenure, Residence and Salary of Circuit Judges Cases are normally heard by panels of no more than three judges.6Office of the Law Revision Counsel. 28 US Code 46 – Assignment of Judges; Panels; Hearings; Quorum The full circuit sits together only in limited situations, most often when a losing party petitions for rehearing en banc and a majority of the circuit’s active judges vote to reconsider the panel’s decision.7Legal Information Institute.

These courts handle more than 50,000 cases per year, and for the vast majority of federal litigation the circuit court’s decision is the final word.4United States Courts. About the U.S. Courts of Appeals Each circuit builds its own body of precedent that every district court within its boundaries must follow, and that body of law can differ from circuit to circuit. When two or more circuits reach opposite conclusions on the same legal question, the result is called a circuit split, and it’s one of the main reasons the Supreme Court agrees to hear a case.
How Circuit Courts Differ From District Courts
District courts are trial courts. A federal case starts there: a plaintiff files a complaint, discovery happens, motions get briefed, and the case eventually goes to trial or settles. District judges and juries decide factual disputes and apply the law to those facts.
Circuit courts sit one level above and decide whether the district court applied the law correctly. On pure legal questions, such as how to interpret a statute or constitutional provision, the circuit court looks at the issue fresh without deferring to the lower court. On a trial judge’s discretionary calls, such as evidentiary rulings or case management, the circuit court gives considerable deference and only reverses when the lower court clearly overstepped. Factual findings get the most protection of all: a circuit court will leave them alone unless no reasonable person could have reached the same conclusion.
The hierarchy runs in one direction. A circuit court’s published decision binds every district court in that circuit. A district court cannot ignore its circuit’s precedent, even if other circuits have gone the other way.
The Federal Circuit and Its Specialized Reach
The Federal Circuit doesn’t cover a region. It has exclusive jurisdiction over certain categories of cases no matter where they originate. Patent disputes are the best known, but the Federal Circuit also hears appeals involving international trade, government contracts, claims for money damages against the United States, trademark decisions from the Patent and Trademark Office, and veterans’ benefits.8Office of the Law Revision Counsel. 28 USC 1295 – Jurisdiction of the United States Court of Appeals for the Federal Circuit9United States Court of Appeals for the Federal Circuit. Types of Cases the Federal Circuit Handles The structure exists because Congress wanted these areas of law to develop under one nationally consistent set of rules rather than thirteen potentially conflicting ones.
The D.C. Circuit plays a somewhat similar role for administrative law. Congress has given it exclusive or primary jurisdiction over review of many federal agency actions, which makes it the most important court in the country for regulatory disputes.
Deadlines for Filing a Federal Appeal
Missing the deadline to file a notice of appeal is one of the most unforgiving mistakes in federal litigation. Courts treat these deadlines as mandatory, and in most situations they cannot be extended after the fact.
- Civil cases between private parties: the notice of appeal must be filed within 30 days after the district court enters its judgment or order.10Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right; When Taken
- Civil cases involving the federal government: when the United States or a federal officer or agency is a party, any party has 60 days to file.10Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right; When Taken
- Criminal cases: a defendant must file within 14 days after the judgment of conviction or the order being appealed is entered.10Legal Information Institute. Federal Rules of Appellate Procedure Rule 4 – Appeal as of Right; When Taken
Certain post-trial motions, such as a motion for a new trial, can reset the clock, so that the appeal deadline runs from the date the court rules on that motion rather than the original judgment. Filing such a motion purely to buy time doesn’t work if the underlying motion is frivolous, and judges see through the tactic quickly.
From a Circuit Court to the Supreme Court
After a circuit court issues its decision, the losing party’s only remaining option in the federal system is to ask the Supreme Court to hear the case. This is done by filing a petition for a writ of certiorari, essentially a request for the Supreme Court to order the circuit court to send up the case record for review.11Office of the Law Revision Counsel. 28 USC 1254 – Courts of Appeals; Certiorari; Certified Questions
The odds are steep. The Court receives more than 7,000 petitions each year and grants plenary review, with full briefing and oral argument, in roughly 80 of them.12Supreme Court of the United States. Supreme Court at Work At least four of the nine justices must vote to take a case before certiorari is granted.13Federal Judicial Center. The Supreme Court’s Rule of Four A circuit split on the legal issue makes a grant more likely, but even then the Court is selective. In the overwhelming majority of federal cases, the circuit court’s decision is the end of the road.
State Circuit Courts Are Trial Courts
Here’s where the terminology flips. Many states use the name “circuit court” for their trial courts of general jurisdiction, the opposite of the federal usage. A state circuit court is typically where a case begins. These courts hold full trials with juries, hear witness testimony, and issue the original judgment.
State circuit courts generally handle the most serious categories of cases: major civil lawsuits above a certain dollar threshold, all felony criminal prosecutions, family law matters, probate, and juvenile cases. Specific dividing lines vary by jurisdiction, but smaller-dollar civil disputes and less serious criminal charges are usually routed to limited-jurisdiction courts such as county courts or magistrate courts. Circuit courts handle everything above that floor.
The internal structure varies too. Some states divide into dozens of judicial districts, each functioning as a separate circuit, with judges sitting in specialized divisions to manage high caseloads. These courts have broad authority: they can issue injunctions, award money damages, and impose sentences ranging from probation to life in prison depending on the offense. Filing fees for civil cases in state-level circuit or general jurisdiction courts typically range from around $50 to over $400, depending on the type and value of the case. For most people, state circuit courts are the courts they’re most likely to interact with directly.
When a Case Moves Between State and Federal Court
A case filed in a state circuit court can sometimes be moved to federal court through a process called removal. The most common basis is diversity jurisdiction: the plaintiff and defendant are citizens of different states and the amount at stake exceeds $75,000. For class actions the threshold jumps to $5,000,000.14Office of the Law Revision Counsel. 28 USC 1332 – Diversity of Citizenship; Amount in Controversy; Costs The defendant must file a notice of removal within 30 days of receiving the initial complaint, and that deadline is mandatory.
Removal only runs one direction: from state court to federal court. The plaintiff chose the state forum, and if the defendant wants it moved, the burden is on the defendant to establish that federal jurisdiction exists. Cases based on diversity jurisdiction cannot be removed more than one year after the lawsuit was originally filed, unless the court finds the plaintiff deliberately manipulated the case to prevent removal. Once in federal court, the case follows federal procedural rules, and any appeal goes to the regional federal circuit court of appeals rather than the state appellate system.
