5.5 Jurisdiction & Court Structure

Key Takeaways

  • Trial courts have original jurisdiction — they hear cases first and find facts; appellate courts review legal errors on the record and do not hear new evidence.
  • Courts of general jurisdiction hear most felonies and major civil cases; courts of limited (or special) jurisdiction handle specific matters like traffic, small claims, family, juvenile, and probate.
  • A typical state court hierarchy is: trial court → intermediate appellate court → state supreme court (the court of last resort).
  • The federal court hierarchy parallels it: U.S. District Court (trial) → U.S. Court of Appeals → U.S. Supreme Court.
  • Subject-matter jurisdiction is a court's authority to hear a particular type of case; personal jurisdiction is authority over the parties.

Quick Answer: Trial courts have original jurisdiction — they hear cases first and determine facts. Appellate courts review legal errors on the record and do not take new evidence. Courts of general jurisdiction handle major felonies and large civil cases; courts of limited (or special) jurisdiction handle specific matters like traffic, small claims, family, juvenile, and probate. The state hierarchy is trial → intermediate appellate → state supreme court; the federal hierarchy is U.S. District → U.S. Circuit Court of Appeals → U.S. Supreme Court.

Why Court Structure Matters for Interpreters

Court interpreter programs run by state courts assign interpreters across many kinds of courts. The same interpreter might work a felony trial in a circuit court, a custody hearing in a family court, a delinquency proceeding in a juvenile court, and an appeal in an intermediate appellate court. Knowing the structure tells you what kind of proceeding you are in, what terminology to expect, and what record-keeping rules apply. The exam's court-related items can also ask about jurisdiction — what kind of court hears which case.

Original vs. Appellate Jurisdiction

Jurisdiction is a court's authority to hear a case. The two basic flavors are:

  • Original jurisdiction — the court hears the case first. Trial courts have original jurisdiction. They take testimony, admit exhibits, and make findings of fact.
  • Appellate jurisdiction — the court reviews a decision already made by a lower court. Appellate courts do not hear witnesses or admit new evidence; they review the record on appeal for legal error and may affirm, reverse, remand, or modify.

An appeal is therefore a review, not a do-over. The appellate court's work is about whether the trial court applied the law correctly, not about who is telling the truth.

General vs. Limited Jurisdiction

State trial courts split into two broad categories:

  • Courts of general jurisdiction — empowered to hear a wide range of civil and criminal cases, including felonies and major civil matters. In many states these are called circuit courts or superior courts or district courts.
  • Courts of limited (or special) jurisdiction — empowered to hear only specific types of cases. Examples include traffic court, municipal court, small claims court, family court, juvenile court, probate court, and landlord-tenant court. Their subject-matter jurisdiction is restricted by statute.

A practical implication: a family court generally cannot hear a felony, and a municipal court generally cannot hear a divorce. The interpreter's assignment depends on the court's subject-matter jurisdiction.

State Court Hierarchy

The typical state court hierarchy has three layers:

LevelCourtFunction
Trial levelCircuit / Superior / District court (general); Municipal / Family / Juvenile / Probate / Traffic (limited)Hears cases first; finds facts
Intermediate appellateCourt of Appeals (often divided into panels or districts)Reviews trial court decisions for legal error
Court of last resortState Supreme Court (in some states, Supreme Court of [State])Final say on state law; discretionary review

Not every state has an intermediate appellate court, but most do. Appeals from a trial court usually go first to the intermediate appellate court, and only then (by permission or right) to the state supreme court. The state supreme court's rulings on state law are final — the U.S. Supreme Court can review only where a federal question is involved.

Federal Court Hierarchy

The federal system parallels the state system:

LevelCourtFunction
Trial levelU.S. District CourtHears federal criminal and civil cases first; there are 94 districts
Intermediate appellateU.S. Court of Appeals (Circuit)Reviews district court decisions; 13 courts of appeals — 11 numbered circuits, the D.C. Circuit, and the Federal Circuit
Court of last resortU.S. Supreme CourtFinal say on federal constitutional and statutory questions

Federal courts hear federal question cases (cases arising under federal law) and diversity cases (civil suits between citizens of different states meeting a jurisdictional amount). Most state-court interpreter work is in state courts, but federally certified interpreters also work in U.S. District Court, especially in federal criminal cases.

Subject-Matter vs. Personal Jurisdiction

Two more terms the exam may use:

  • Subject-matter jurisdiction — the court's authority to hear the type of case. A probate court has subject-matter jurisdiction over estates; a family court over divorces. This generally cannot be waived — if the court lacks subject-matter jurisdiction, the case must be transferred or dismissed.
  • Personal jurisdiction — the court's authority over the parties. A court obtains personal jurisdiction over the plaintiff when the plaintiff files, and over the defendant through service of process or the defendant's appearance. Personal jurisdiction can be waived.

Why an Interpreter May Appear in Different Courts

State court interpreter programs typically assign interpreters where needed, regardless of the specific court. As a result, an interpreter may work:

  • A felony arraignment in a circuit court.
  • A custody modification in family court.
  • A delinquency adjudication in juvenile court.
  • A deposition in a civil case at a law office.
  • An appeal before a panel of appellate judges — though appellate argument is often handled in written briefs plus oral argument, the interpreter may be needed for the party or witness who appears.

Understanding the structure helps you orient quickly in each setting and use the correct terminology for that court's work.

Exam Scenario Hooks

  • A court-related item may ask which court hears cases first — a trial court (original jurisdiction).
  • An item may ask which court reviews legal errors on the record — an appellate court.
  • An item may ask which court typically handles a divorce — family court (limited jurisdiction).
  • An item may ask whether an appellate court hears new witnesses — no, it reviews the record.

Key Takeaways

  • Trial courts find facts; appellate courts review law.
  • General jurisdiction = broad range; limited jurisdiction = specific matters only.
  • State hierarchy: trial → intermediate appellate → state supreme court.
  • Federal hierarchy: U.S. District → U.S. Court of Appeals → U.S. Supreme Court.
  • Subject-matter jurisdiction cannot be waived; personal jurisdiction can.
