Defending Against Federal Conspiracy Charges – 18 U.S.C. § 371
Federal Criminal Defense Lawyers
Federal conspiracy charges under 18 U.S.C. § 371 are among the most powerful and frequently used tools in federal prosecutions.
Prosecutors often use conspiracy allegations to expand criminal liability, sweep in peripheral defendants, and dramatically increase sentencing exposure—even when a person never committed the underlying offense themselves.
Because conspiracy law is broad, technical, and heavily fact-driven, strong federal defense representation is critical from the earliest stages of an investigation.
Your best hope for a favorable outcome is with a highly experienced criminal defense attorney at Eisner Gorin LLP. To schedule a consultation, call (818) 781-1570 or contact us here.
What Is Federal Conspiracy Under 18 U.S.C. § 371?
Under federal law, a conspiracy exists when:
-
Two or more people agree to commit a federal crime or to defraud the United States, and
-
At least one conspirator commits an overt act in furtherance of that agreement
Importantly, the government does not need to prove:
-
A written agreement
-
That every conspirator committed a criminal act
-
That the underlying crime was ever completed
The crime is the agreement itself, combined with any act—however small—taken to further the plan.
Why Federal Conspiracy Charges Are So Common
Federal prosecutors rely heavily on conspiracy charges because:
-
Only one conspirator needs to act for all to be liable
-
Defendants can be convicted based on circumstantial evidence
-
Peripheral participants can be charged alongside major offenders
-
Conspiracy allows prosecutors to introduce co-conspirator statements as evidence
This is why individuals with minor, indirect, or limited involvement often face the same charges as those who committed the core criminal conduct.
The Overt Act Requirement
Most federal conspiracy statutes—including 18 U.S.C. § 371—require proof of an overt act.
An overt act:
-
Does not have to be illegal
-
Must be intended to further the conspiracy's objective
-
Can be committed by any conspirator
Once an overt act occurs, every conspirator becomes criminally liable, even if they were unaware of that specific act.
Conspiracy to Commit an Offense vs. Conspiracy to Defraud
Conspiracy to Commit a Federal Crime
This involves agreeing to violate another federal statute, such as:
Conspiracy to Defraud the United States
This covers schemes that:
-
Interfere with lawful government functions
-
Deceive federal agencies
-
Obstruct regulatory or enforcement processes
No financial loss is required—only impairment of government operations.
Common Federal Crimes Charged With § 371 Conspiracy
Conspiracy charges frequently accompany:
-
Wire fraud and mail fraud
-
Money laundering
-
Health care fraud
-
Drug trafficking
-
Counterfeiting
While § 371 carries a maximum of five years, the penalties for the underlying offense often far exceed that—making conspiracy a gateway to much harsher sentences.
Why Peripheral Defendants Are Especially Vulnerable
Federal conspiracy law allows prosecutors to hold defendants responsible for:
-
Crimes committed by co-conspirators
-
Acts they never personally committed
-
Foreseeable offenses committed in furtherance of the conspiracy
This means that someone on the periphery of an alleged scheme may face the same exposure as the principal actors.
How Federal Prosecutors Prove Conspiracy
To obtain a conviction, prosecutors must prove beyond a reasonable doubt:
-
An agreement to commit a federal crime or defraud the U.S.
-
Knowledge of the unlawful objective
-
Intent to join and further the conspiracy
-
At least one overt act in furtherance of the plan
Mere association, presence, or awareness is not enough.
Key Defense Strategies Against Federal Conspiracy Charges
An experienced federal defense lawyer may challenge conspiracy allegations by showing:
No Agreement
-
Conversations ≠ agreement
-
Listening ≠ joining
-
Association ≠ conspiracy
No Criminal Intent
-
The defendant believed the conduct was lawful
-
The defendant acted for innocent purposes
No Overt Act
-
Acts cited were unrelated or lawful
-
Conduct did not further any criminal objective
Withdrawal From the Conspiracy
-
The defendant withdrew before any overt act
-
Withdrawal can limit liability and sentencing exposure
Constitutional Violations
-
Illegal searches or seizures
-
Improper wiretaps
-
Coerced statements
Successful defenses often involve pretrial motions, suppression of evidence, and targeted cross-examination.
Why Early Federal Defense Matters
Conspiracy cases are often built:
-
Overlong investigations
-
Using cooperating witnesses
-
Through recorded communications
Early representation allows counsel to:
-
Intervene before indictment
-
Limit exposure through negotiation
-
Challenge grand jury evidence
-
Preserve critical defenses
Once indicted, options narrow significantly.
