FEDERAL CRIMES LAW — CALIFORNIA
Federal vs State Prosecution in California — Which Court Handles Your Case
Many crimes in California can be prosecuted in either state or federal court. Federal prosecution typically means harsher sentences, no parole, and prosecution by the US Attorney's Office. Understanding the difference is critical to your defense strategy.

What Is Federal vs State Prosecution California Under California Law?
Legal Framework. Federal and California state courts have separate criminal jurisdiction. Congress gave federal district courts original jurisdiction over federal offenses in 18 U.S.C. § 3231. A federal case therefore requires a charged violation of a federal criminal statute, not merely conduct that is serious or occurred in California. Common federal predicates include interstate commerce, use of the mail or wires, federal property or funds, immigration, firearms, controlled-substance distribution, or an offense against a federal officer. Under the Supremacy Clause, U.S. Const. art. VI, cl. 2, valid federal law prevails over conflicting state law, but that clause does not automatically transfer every California crime into federal court. The charging decision is generally made by the United States Attorney’s Office after investigation by agencies such as the FBI, DEA, ATF, Homeland Security Investigations, IRS-CI, or a federal task force.
The Prosecution's Burden. The same conduct may violate both California and federal law. California prosecutors commonly file offenses under the Penal Code, Health and Safety Code, or Vehicle Code in Superior Court; in Los Angeles County, cases generally proceed through the Los Angeles Superior Court with prosecution by the Los Angeles County District Attorney or, in some matters, the City Attorney. Federal felony cases in Los Angeles are ordinarily prosecuted by the U.S. Attorney’s Office in the U.S. District Court for the Central District of California. Federal offenses are not California “wobblers.” Whether an offense is a felony or misdemeanor, and its sentencing range, depends on the particular federal statute and the United States Sentencing Guidelines. Unlike California’s former indeterminate sentencing framework, the federal system abolished parole for offenses committed after November 1, 1987, although supervised release can follow custody.
Potential Consequences. Dual prosecution is a central issue when state and federal authorities investigate the same episode. The Double Jeopardy Clause generally does not bar prosecutions by separate sovereigns: California and the federal government may each enforce their own laws arising from the same conduct. See Gamble v. United States (2019) 587 U.S. 678. That does not mean two cases are inevitable or that parallel cases must proceed without limits. Prosecutors may coordinate, one office may defer to the other, and successive state prosecution can raise additional California statutory and constitutional issues depending on the facts. Federal charging often appears in cases involving alleged drug trafficking organizations, firearms, fraud, interstate activity, federal benefits, public corruption, or task-force investigations, while California retains broad authority over ordinary local crimes. The governing question is not which forum is “more serious,” but whether each sovereign can prove a distinct violation of its own law.
05 — Defense Strategies
How Rubin Law Defends Federal vs State Prosecution California Charges
Rubin Law, P.C. attacks the elements of 18 U.S.C. §3231 / Art. VI Supremacy Clause and drives outcomes that avoid conviction where possible.
Challenge the Federal Jurisdictional Nexus
A federal prosecutor must prove every jurisdictional element in the charged statute. The required connection may be use of interstate wires or mail, effect on interstate commerce, a federal program or federal property, an offense involving a federal officer, or another specifically defined federal hook. The breadth of federal jurisdiction varies sharply by statute; it cannot be assumed from the fact that conduct happened in California or involved an out-of-state business. The defense should identify the exact nexus alleged in the indictment, test the evidence supporting it, and seek dismissal or acquittal if the government cannot prove that element beyond a reasonable doubt.
U.S. Const. amend. IV
Attack the Indictment or Complaint
Federal charges must give constitutionally adequate notice of the offense and must allege the statute’s essential elements. In felony cases, the Fifth Amendment ordinarily requires an indictment returned by a grand jury unless indictment is waived; misdemeanors may proceed by information. A motion under Federal Rule of Criminal Procedure 12 can challenge defects that must be raised before trial, including duplicity, multiplicity, lack of specificity, or an improperly alleged offense. A bill of particulars may be appropriate where the charging document is too vague to permit meaningful trial preparation. These motions can narrow the case, expose an invalid theory, and protect against unfair surprise or double-jeopardy uncertainty.
17 CCR §1219.3
Suppress Federal or Task-Force Evidence
A federal case often grows out of a joint investigation involving LAPD, LASD, local task forces, and federal agents. The Fourth Amendment applies regardless of which agency performed the search, seizure, arrest, phone extraction, tracking, or interrogation. Defense counsel should obtain warrants, affidavits, reports, body-camera footage, dispatch records, and digital-forensic materials; examine probable cause, warrant scope, execution, staleness, inventory procedures, and consent; and litigate suppression under Federal Rule of Criminal Procedure 12. Statements may also be excluded if obtained in violation of Miranda or involuntarily. Exclusion of a key phone, firearm, narcotics seizure, or confession can fundamentally change federal charging and plea leverage.

Separate the Client From the Conspiracy
Federal conspiracy charges can sweep in people who had contact with an alleged organization but never knowingly joined its criminal agreement. The government must prove more than association, presence, friendship, family ties, or a series of legitimate transactions. Depending on the statute, it must establish a knowing and voluntary agreement to pursue the unlawful objective and the required additional elements. The defense can use communications, financial records, work history, travel evidence, and the government’s own surveillance to show lack of knowledge, withdrawal, limited participation, or conduct inconsistent with the alleged agreement. This is particularly important in federal drug, fraud, firearms, and racketeering investigations.
VC §23152
Litigate Custody Exposure and Sentencing Facts
Federal sentencing commonly turns on disputed facts beyond the basic offense label: drug quantity, intended loss, number of victims, firearm possession, role in the offense, obstruction, prior convictions, and acceptance of responsibility. Those facts can substantially affect the advisory guideline calculation under 18 U.S.C. § 3553(a) and the United States Sentencing Guidelines, and some statutes carry mandatory minimum penalties. A defense strategy should begin before any plea by identifying proof problems, preserving objections to the presentence report, developing mitigation, and challenging unreliable hearsay or unsupported enhancements. A carefully built factual record may affect charging, plea terms, guideline range, and the sentencing judge’s ultimate decision.
17 CCR §1219.1
Address Parallel State and Federal Proceedings
When the same conduct is under investigation by the Los Angeles County District Attorney and the U.S. Attorney’s Office, defense decisions in one forum can affect the other. A state plea, interview, preliminary-hearing testimony, discovery production, or proffer may create admissions or impeachment material for federal prosecutors. Conversely, federal detention, indictment timing, and discovery may alter how a state case is handled. Counsel should determine early whether both sovereigns are actively investigating, identify overlaps in witnesses and evidence, and avoid resolving one case on assumptions about the other. Although dual sovereignty may permit separate prosecutions, coordination, timing, and a disciplined cross-forum defense can materially reduce avoidable exposure.

Questions
Frequently Asked — Federal vs State Prosecution California
Can California and the federal government charge me for the same conduct?
Yes. The same conduct can violate both California law and federal law, and the Double Jeopardy Clause generally permits separate prosecutions by separate sovereigns. California prosecutes violations of state law; the federal government prosecutes violations of federal law. The Supreme Court reaffirmed this “dual-sovereignty” rule in Gamble v. United States (2019) 587 U.S. 678. In practice, a state case and a federal case do not always both get filed. The Los Angeles County District Attorney, a city prosecutor, and the U.S. Attorney’s Office may communicate, defer, or pursue different aspects of an investigation. But a state dismissal or plea does not automatically prevent federal charges, so no one should assume that resolving one case ends all criminal exposure.
What makes a criminal case federal instead of a California state case?
A case is federal when the government charges a violation of a federal criminal statute and can prove that statute’s required jurisdictional basis. Federal district courts have original jurisdiction over federal offenses under 18 U.S.C. § 3231. The basis may involve interstate mail or wire communications, interstate commerce, federal funds or property, immigration, federal taxes, controlled-substance trafficking, firearms, or conduct involving federal officers. A robbery, drug sale, fraud, or gun allegation does not become federal simply because federal agents participate in the investigation. The indictment must identify a federal crime, and the prosecution must prove its elements. California can prosecute its own separate offenses in Superior Court even when federal authorities are also involved.
Will I receive a harsher sentence in federal court than in California?
Not automatically, but federal exposure can be more severe depending on the statute, mandatory minimums, guideline calculation, criminal history, and the facts the government can prove. Federal judges use the advisory United States Sentencing Guidelines and must consider the factors in 18 U.S.C. § 3553(a). Some federal statutes impose mandatory minimum prison terms; others do not. Federal parole was abolished for offenses committed after November 1, 1987, though a court may impose supervised release after imprisonment. California sentencing follows different statutes and procedures, including possible county-jail or state-prison terms, probation options, and programs that may not have a federal equivalent. A meaningful comparison requires the actual federal statute, proposed guideline range, and potential California charges—not general assumptions.
Can a California case be moved into federal court because it is serious?
No. Seriousness alone does not create federal criminal jurisdiction. A California prosecution does not simply transfer to federal court because the allegations involve violence, a large amount of money, drugs, or media attention. Federal prosecutors must independently charge a federal offense under a federal statute, and the federal court’s authority rests on 18 U.S.C. § 3231. In some civil cases, a defendant may remove a case from state court to federal court under separate removal statutes, but that is not the ordinary mechanism for state criminal prosecutions. Federal authorities may take over an investigation or bring their own federal case, while California prosecutors dismiss, continue, or separately litigate state charges. The procedural posture must be assessed case by case.
If federal agents questioned or searched me in Los Angeles, is my case federal?
Not necessarily. FBI, DEA, ATF, Homeland Security Investigations, and other federal agencies frequently work with LAPD, LASD, and regional task forces. Their involvement may mean a federal investigation is underway, but state prosecutors can still file California charges. Conversely, local police may develop evidence later used in a federal indictment. What matters is the charging document: a federal felony is ordinarily initiated by a grand-jury indictment, unless waived, and proceeds in U.S. District Court; a California felony ordinarily proceeds through the Los Angeles Superior Court process. Regardless of forum, the legality of the stop, search, arrest, and interrogation must be evaluated under the Fourth, Fifth, and Sixth Amendments and applicable procedural rules.
What should I do if I may face both federal and state charges?
Do not give statements, consent to interviews, sign a proffer or cooperation agreement, or resolve a state case without counsel who has evaluated the potential federal consequences. Statements made to LAPD, LASD, a state prosecutor, or in a California court can be used by federal investigators, subject to the rules of evidence and constitutional protections. Preserve notices, search-warrant paperwork, bail documents, charging papers, and contact information for every agency involved. Counsel should identify the possible statutes, whether a federal grand-jury investigation exists, applicable detention issues, potential mandatory minimums, and overlap between the two matters.
