A criminal case may be prosecuted federally when the alleged conduct violates federal law or falls within federal jurisdiction. This can happen when an offense involves interstate activity, federal agencies, federal property, or certain financial crimes. In those situations, federal prosecutors may bring charges in U.S. District Court after reviewing the investigation and evidence gathered by federal agents.
What Does It Mean When a Case “Goes Federal”?
In practice, criminal cases are not literally “kicked to the feds” or transferred from one court to another. Instead, federal prosecutors decide whether to file charges under federal law after reviewing the facts of an investigation.
Federal criminal cases are prosecuted in U.S. District Court by Assistant U.S. Attorneys. Many of these cases begin with investigations conducted by federal agencies such as the FBI, DEA, ATF, Homeland Security Investigations, or IRS Criminal Investigation.
Federal jurisdiction comes into play when a crime violates federal law or involves matters the federal government has authority to regulate. This can include crimes that cross state lines, involve federal programs or property, or fall under federal statutes. When federal prosecutors believe the conduct fits within those laws, they may bring federal charges.
If you are under investigation or believe your case may involve federal authorities, speaking with a federal criminal defense attorney may help you understand the situation and your legal options.
What Types of Crimes Are Often Prosecuted Federally?
Certain categories of crimes are more likely to be prosecuted in federal court because they fall within federal jurisdiction or involve national investigative agencies:
- Interstate offenses–Crimes that cross state lines often fall under federal authority. Examples may include online fraud, trafficking offenses, and certain cybercrimes involving interstate communications or transactions.
- Large-scale criminal activity–Federal prosecutors frequently handle cases involving organized criminal operations, large drug trafficking networks, or conspiracy charges that involve multiple participants or jurisdictions.
- Financial and white-collar crimes–Many financial crimes are prosecuted federally because they involve banks, financial institutions, or interstate transactions. Common federal offenses include wire fraud, securities fraud, bank fraud, healthcare fraud, and tax-related crimes.
- Crimes involving federal property or officials–Federal jurisdiction may also apply when an offense occurs on federal property, involves federal employees, or targets federal programs or officials.
Because federal investigations often involve complex financial records or multi-state conduct, these cases may involve lengthy investigations before charges are filed.
Can a Case Start in State Court and Then Become Federal?
Yes. Some conduct may violate both state and federal law. This is sometimes referred to as dual jurisdiction. In these situations, a case may begin with a local investigation or even state charges. Federal prosecutors may later review the case and determine that federal charges are appropriate. When that occurs, the federal government may file its own charges in federal court.
In some cases, state charges are dismissed after federal prosecutors bring charges based on the same conduct. Ultimately, prosecutors determine whether a case will proceed in state court, federal court, or both.
How Are Federal Criminal Cases Different From State Cases?
Federal criminal cases often involve different investigative procedures and court processes than state cases.
Federal investigations may last months or even years before charges are filed. During that time, investigators may gather financial records, conduct surveillance, execute search warrants, or issue subpoenas for documents and testimony.
Federal cases are typically initiated through a grand jury indictment, and the prosecution is handled by Assistant U.S. Attorneys in U.S. District Court. Federal courts also apply sentencing guidelines that may influence how penalties are determined after a conviction.
Because of the scope of these investigations and the complexity of federal law, federal criminal cases are often more document-heavy and procedurally detailed than many state prosecutions.
Signs a Criminal Case May Become Federal
Some investigations may involve federal authorities from the beginning. In other situations, federal involvement may develop as the investigation progresses.
Possible signs that a case may involve federal authorities include:
- Contact from federal agents such as the FBI, DEA, or ATF
- Receipt of a federal grand jury subpoena
- Search warrants executed by federal agents
- Investigations involving activity across state lines
- Financial investigations involving banks or interstate transactions
These factors do not automatically mean federal charges will be filed, but they may indicate that federal authorities are involved in the investigation.
What Should You Do If Federal Agents Contact You?
Federal investigations often begin long before charges are filed. Agents may contact individuals for interviews or request documents during the investigative process.
Statements made during these interactions may become part of the investigation. Because of this, individuals contacted by federal authorities should consult an attorney before answering questions or participating in interviews.
