Definition
Criminal courts are tribunals established by law to hear and adjudicate cases in which the state prosecutes individuals or entities for conduct designated as criminal offenses. Their authority is distinct from civil courts: the proceeding is brought in the name of a sovereign (the People, the State, the United States), the standard of proof is beyond a reasonable doubt, and the potential consequences include imprisonment, fines, probation, or in capital cases, death.
The term "criminal courts" is not the name of a single court but a category. It encompasses a wide range of tribunals differentiated by subject matter, severity of offense, and level of government:
1. Trial courts of general criminal jurisdiction hear felony-level and serious misdemeanor matters. In the federal system, this is the U.S. District Court. In states, these are variously called superior courts, circuit courts, district courts, or courts of common pleas.
2. Courts of limited or inferior criminal jurisdiction handle petty offenses, misdemeanors, and preliminary proceedings (arraignments, bail hearings, preliminary examinations). These include magistrates' courts, municipal courts, and justice-of-the-peace courts.
3. Appellate courts with criminal jurisdiction review convictions and sentences from trial courts. In the federal system, the U.S. Courts of Appeals and the Supreme Court perform this function. States maintain parallel appellate structures.
4. Specialized criminal courts exercise jurisdiction over defined categories of defendants or offenses: juvenile courts, drug courts, mental health courts, domestic violence courts, military courts (courts-martial), and tribal courts.
Common Confusion
The label "criminal court" attached to a particular building or division can mislead researchers. In many jurisdictions, the same trial court of general jurisdiction hears both civil and criminal matters; in others, the criminal docket is assigned to a separately named division. The existence of a court called "Criminal Court" in one jurisdiction does not mean it performs the same function as a court bearing that name in another. Researchers should identify the specific court by its enabling statute and subject-matter jurisdiction, not its popular name alone.
Recognized Forms
/SUBTYPES
Federal criminal courts: U.S. District Courts (trial), U.S. Courts of Appeals (intermediate appellate), U.S. Supreme Court (final appellate). Magistrate judges handle preliminary proceedings and, with consent, misdemeanor trials.
State felony courts: Courts of general jurisdiction, denominated differently by state.
State inferior criminal courts: Limited jurisdiction courts for misdemeanors, infractions, and preliminary matters.
Military courts: Courts-martial and the service Courts of Criminal Appeals, with final review in the U.S. Court of Appeals for the Armed Forces (CAAF) and discretionary Supreme Court review.
Specialized courts: Drug courts, mental health courts, veterans courts, domestic violence courts — problem-solving courts with rehabilitative orientations operating within the criminal justice framework.
Juvenile courts: Exercise jurisdiction over minors charged with delinquent acts; procedurally distinct from adult criminal courts, though the distinction has narrowed since the constitutional reforms of the late 1960s.
Why It Matters in Research
The phrase "criminal courts" in historical sources almost never refers to a stable or uniform set of tribunals. Researchers working in pre-twentieth-century American or English materials will encounter courts whose criminal jurisdiction was incident to broader authority — quarter sessions, courts of oyer and terminer, courts of general sessions, the English Central Criminal Court — rather than free-standing criminal tribunals in the modern sense. The structure of criminal adjudication was substantially reorganized in both England and the United States across the nineteenth and twentieth centuries.
For English sources, the relevant historical courts include the Central Criminal Court (established 1834 for London and surrounding counties), courts of oyer and terminer and general gaol delivery (which traveled on circuit), quarter sessions (county-level, presided over by justices of the peace, handling misdemeanors and lesser felonies), the Court for Crown Cases Reserved (appellate, established 1848, predecessor to the Court of Criminal Appeal created in 1907), and the Queen's Bench Division of the High Court. Rapalje & Lawrence cross-reference all of these under the entry for CRIMINAL COURTS rather than defining the term directly — a signal that the concept was understood as an aggregate category pointing outward to specific institutional entries. Researchers using that source should follow those cross-references.
For American federal practice, the current structure dates largely from the Judiciary Acts, the Criminal Justice Act, and subsequent statutory reorganizations. Jurisdictional thresholds between magistrate judges and district judges, and the scope of felony versus misdemeanor jurisdiction, have shifted and should be verified against the governing statute for the period under study.
A significant research trap in multi-jurisdictional work: courts styled "criminal court" or "court of criminal jurisdiction" in older American sources were sometimes courts of limited jurisdiction; in other states, the same label denoted general jurisdiction. Do not assume equivalence across states or across time.
Military criminal jurisdiction is a separate system with its own procedural rules, appellate structure, and constitutional framework. Cases arising from courts-martial should not be researched through civilian criminal court materials without accounting for the Uniform Code of Military Justice and the specialized appellate chain.
Historical Dictionary Support
Rapalje & Lawrence do not offer a substantive definition of "criminal courts" as a concept. The entry serves instead as a navigational pointer, directing readers to specific court entries: CENTRAL CRIMINAL COURT, COURT FOR CROWN CASES RESERVED, LORD HIGH STEWARD, OYER AND TERMINER, QUARTER SESSIONS, and QUEEN'S BENCH. The accompanying Latin maxim — Crimen læsæ majestatis omnia alia crimina excedit quoad pænam ("The crime of treason exceeds all other crimes in its punishment," citing Coke's Third Institute) — appears as contextual matter, not as a definition of the courts themselves.
This approach reflects the nineteenth-century understanding: there was no single unified institution called a "criminal court." Criminal jurisdiction was distributed across multiple courts depending on the gravity of the offense, the rank of the accused, the venue, and the procedural posture. The absence of a substantive definition in Rapalje & Lawrence is itself informative — it confirms that researchers should look to specific court entries rather than to any overarching doctrinal definition.
No other source dictionaries are represented in the current entry. Researchers should note that later American legal dictionaries (Black's, Bouvier's) provide more granular treatment of specific criminal courts but similarly treat the category as organizational rather than doctrinal.
Jurisdictional Note
Criminal court structure varies substantially by state. Some states have unified trial courts; others maintain a tiered system with distinct inferior and superior criminal courts. Jurisdictional thresholds for felony versus misdemeanor matters, and the scope of preliminary proceedings before inferior courts, differ enough to require jurisdiction-specific verification. Military criminal jurisdiction is a fully separate system from civilian federal and state criminal courts.
