State court (United States)

State court (United States). In the United States, a state court is a court established by a state government, as opposed to the federal courts established by the United States Congress under the United States Constitution. These courts form the judicial branch of each state government and handle the vast majority of legal disputes in the nation, from traffic violations to complex civil litigation and serious criminal prosecutions. Their structure, jurisdiction, and procedures are defined by the individual State constitution and statutes enacted by the State legislature.

Structure and organization

The organization of state courts varies significantly across the fifty states, but most follow a hierarchical model. At the apex is the court of last resort, typically called the Supreme Court (e.g., the Supreme Court of Texas), though some states use names like the Massachusetts Supreme Judicial Court or the New York Court of Appeals. Below this highest court, most states maintain an intermediate Appellate court to review decisions from trial courts, such as the California Courts of Appeal or the Illinois Appellate Court. The foundational level consists of general and limited jurisdiction Trial courts, which may be organized by county or judicial district, like the Superior Court of Los Angeles County or the Circuit Court of Cook County. Many states also operate specialized courts, such as Probate courts, Family courts, and Juvenile courts, to handle specific legal matters. Administration is often overseen by a state-level body like the Judicial Council of California or the Office of Court Administration in Texas.

Jurisdiction and powers

State courts possess broad Jurisdiction under the Tenth Amendment to the United States Constitution, handling all cases not exclusively reserved for the federal judiciary. This includes the vast majority of Criminal law matters, from misdemeanors to felonies like murder prosecuted under the Pennsylvania Crimes Code. They also adjudicate most civil disputes, including Tort claims, Contract enforcement, Family law issues like divorce and child custody, and matters of Probate and Trust law. State courts have the power of Judicial review over state laws and executive actions, interpreting their own State constitution and statutes, a principle established in cases like the Virginia Supreme Court decision in *Commonwealth v. Caton*. Their authority is territorial, generally limited to the geographic boundaries of the state, and they apply both state Common law and Statutory law.

Selection and tenure of judges

Methods for selecting state Judges differ widely, reflecting a mix of democratic appointment and electoral processes. Many states, such as California and New York, use a system of Gubernatorial appointment subject to confirmation by the State Senate. Other states, like Texas and Illinois, employ Partisan elections or Nonpartisan elections for judicial offices. A hybrid model known as the Missouri Plan (or merit selection), used in states including Missouri and Kansas, involves appointment from a nominating commission followed by periodic Retention elections. Terms of office range from a few years for some trial court judges to lengthy terms or even lifetime tenure for justices on high courts like the Rhode Island Supreme Court. Removal of judges typically requires proceedings before a commission like the Commission on Judicial Performance and may involve impeachment by the State legislature.

Relationship with federal courts

The state and federal court systems operate concurrently under the framework of Dual sovereignty. Federal courts, including the United States district courts and the United States Supreme Court, have limited jurisdiction defined by Article Three of the United States Constitution, primarily over Federal question jurisdiction and Diversity jurisdiction. State courts have concurrent jurisdiction over many federal questions and can hear claims arising under federal statutes like the Americans with Disabilities Act of 1990. However, under the Supremacy Clause, federal law is supreme in conflicts with state law. Decisions from a state's highest court on federal constitutional issues may be reviewed by the United States Supreme Court via a Writ of certiorari, as exemplified in landmark cases like Gideon v. Wainwright. The Anti-Injunction Act and principles of Abstention doctrine, such as those outlined in *Younger v. Harris*, generally prohibit federal courts from interfering with ongoing state court proceedings.

Types of state courts

Beyond the basic trial-appellate-supreme court structure, states maintain a diverse array of specialized judicial bodies. Courts of general jurisdiction, often called Superior courts, Circuit courts, or District courts, hear major criminal cases and civil suits above a monetary threshold. Courts of limited jurisdiction handle minor matters and include Municipal courts for city ordinance violations, Justice of the peace courts in states like Arizona, and Small claims courts for minor civil disputes. Specialized tribunals include Juvenile courts for delinquency and dependency cases, Family courts handling divorce and adoption, Probate courts administering estates, and Drug courts focused on rehabilitation. Many states also have Tax courts, such as the Oregon Tax Court, and Court of Claims to hear suits against the state government. Some, like the Delaware Court of Chancery, have unique historical courts for specific legal areas like Equity (law).
