Introduction
The same criminal conduct can sometimes result in either state or federal prosecution—or both. For researchers working with court documents, understanding which court system handled a case determines where to find records, what procedures applied, and what penalties were possible.
Federal cases go through different courts, use different evidence rules, and often result in different sentences than state prosecutions for similar conduct. This guide explains how jurisdiction is determined and what it means for case research.

The Basic Distinction
State Court Jurisdiction
State courts handle:
Traditional crimes:
- Murder (usually)
- Assault and battery
- Robbery and theft
- Most drug offenses
- Property crimes
- Domestic violence
The default rule:
- Most crimes are state offenses
- Each state has its own criminal code
- Local law enforcement investigates
- County prosecutors bring charges
Federal Court Jurisdiction
Federal courts handle:
Specifically federal crimes:
- Crimes on federal property
- Crimes against federal officials
- Immigration offenses
- Tax evasion
- Certain firearms offenses
Crimes with federal “hooks”:
- Interstate commerce connection
- Use of mail or wire communications
- Crossing state lines
- Federal banking system involvement
Common Federal Jurisdictional Hooks
Wire Fraud (18 U.S.C. § 1343)
One of the most frequently used federal statutes:
Requirements:
- Scheme to defraud
- Intent to defraud
- Material misrepresentation
- Use of interstate wire communications (phone, internet, email)
Why it matters:
- Nearly any fraud involving phone or internet qualifies
- Allows federal prosecution of schemes that might otherwise be state matters
- Five-year maximum sentence (20 years if financial institution involved)
Mail Fraud (18 U.S.C. § 1341)
The original federal fraud statute:
Requirements:
- Scheme to defraud
- Use of US mail or private carrier
- Intent to defraud
Why it matters:
- Any scheme using mail is potentially federal
- Includes packages, letters, promotional materials
- Often charged alongside wire fraud
Interstate Transportation
Crimes involving crossing state lines:
Examples:
- Kidnapping across state lines (federal)
- Stolen property transported interstate (federal)
- Murder-for-hire using interstate facilities (federal)
- Domestic violence involving interstate travel (federal)
Federal Institutions
Crimes involving federal entities:
Examples:
- Bank fraud (federally insured banks)
- Healthcare fraud (Medicare/Medicaid)
- Federal program fraud
- Crimes on federal property
Dual Sovereignty
What It Means
The same conduct can be prosecuted in both state and federal court:
Not double jeopardy:
- Separate sovereigns doctrine
- State and federal governments are separate entities
- Each can prosecute for violations of its own laws
- Supreme Court has upheld this principle
When It Happens
Factors that may trigger dual prosecution:
- High-profile cases requiring visible federal involvement
- State prosecution results in inadequate sentence
- Federal resources needed for complex investigation
- Civil rights implications
- Significant public interest
Practical Reality
Despite legal possibility:
- Dual prosecution is relatively rare
- Prosecutors often coordinate
- One jurisdiction typically takes lead
- Resources usually allocated to single prosecution
Comparing Systems
Investigation Differences
State investigations:
- Local police, sheriff’s office, state police
- District attorney’s office involvement
- Limited resources for complex cases
- Geographic scope limitations
Federal investigations:
- FBI, DEA, ATF, IRS Criminal Investigation, Secret Service
- Specialized expertise and resources
- National scope
- Grand jury subpoena power
Procedural Differences
State courts:
- Procedures vary by state
- Preliminary hearing or grand jury (varies)
- Discovery rules vary
- Sentencing varies dramatically by state
Federal courts:
- Uniform federal rules
- Grand jury indictment required for felonies
- Broader discovery obligations
- Federal Sentencing Guidelines (advisory)
Sentencing Differences
State sentences:
- Determined by state law
- Wide variation between states
- Parole often available
- Good time credits vary
Federal sentences:
- Sentencing Guidelines calculate range
- Generally longer for same conduct
- No federal parole (abolished 1984)
- Good time limited to 54 days per year
Research Implications
Finding Records
State court records:
- County clerk of court
- State court electronic systems (varies)
- Some states lack electronic access
- May require in-person requests
Federal court records:
- PACER (Public Access to Court Electronic Records)
- Standardized nationwide system
- Electronic access to most filings
- $0.10 per page (capped at $3.00 per document)
Understanding Procedures
When reading court documents, jurisdiction matters:
State case documents:
- Procedures specific to that state
- Terminology may differ
- Appeal routes vary
- Sentencing frameworks differ
Federal case documents:
- Federal Rules of Criminal Procedure
- Uniform terminology
- Standardized appeal routes
- Sentencing Guidelines references
Why Certain Crimes Go Federal
Murder-for-Hire Cases
Federal jurisdiction typically applies when:
- Interstate travel or communication involved (common)
- Use of mail or wire in solicitation
- 18 U.S.C. § 1958 specifically covers this
- Penalties: 10 years (no death); death/life (if death results)
Financial Crimes
Federal jurisdiction often applies because:
- Banking system is federally regulated
- Wire transfers cross state lines
- Mail used in schemes
- SEC regulates securities nationally
Healthcare Fraud
Federal jurisdiction because:
- Medicare/Medicaid are federal programs
- Fraud against federal programs is federal crime
- Interstate billing and communications
- Significant federal resources involved
Practical Examples
From Our Coverage
Financial crime (federal):
Field of Schemes – Wire fraud, bank fraud involving federally insured institutions, grain transactions crossing state lines.
Murder-for-hire (federal):
Wrong Target Again and Again – Interstate communication in solicitation, 18 U.S.C. § 1958 charges.
Healthcare fraud (federal):
Dollars Over Death – Medicare fraud, federally funded healthcare program.
For Researchers
Determining Jurisdiction
When researching a case:
1. Check the court name – U.S. District Court = federal; State v. or People v. = state
2. Look at statutes charged – U.S.C. = federal; State code = state
3. Identify the investigating agency – FBI, DEA = likely federal; Local PD = likely state
4. Consider the crime type – Some crimes are almost always federal
Why It Matters
Understanding jurisdiction affects:
- Where to find documents
- What procedures to expect in documents
- How to interpret sentencing
- What appeals look like
- Available records and access
