NACDL is actively working on reform in the area of conspiracy law. Currently, the federal criminal code has a number of conspiracy provisions, but the provision to defraud the United States, 18 U.S.C. § 371, is especially worrisome. It has been interpreted to include almost any effort to interfere with a function of the federal government through deceit. NACDL is working to reform this vague provision, and other aspects of criminal conspiracy law, to ensure only those truly deserving of punishment are swept up in its net.
Adding to the concerns raised by the amorphous federal criminal conspiracy statute, the U.S. Supreme Court held in Pinkerton v. United States that a conspirator is criminally liable for the foreseeable substantive crimes of his co-conspirators in furtherance of the conspiracy, even if the conspirator himself played no part in the substantive offense and did not intend that it occur. This is the only case in the federal system that creates a common-law, judge-made theory of criminal liability. NACDL advocates that the basis for a criminal conviction should not be based on the sole decree of federal judges, but on careful legislative judgement. Read the full Pinkerton decision.
Federal Criminal Conspiracy Statute
§ 371. Conspiracy to commit offense or to defraud United States
If two or more persons conspire either to commit any offense against the United States, or to defraud the United States, or any agency thereof in any manner or for any purpose, and one or more of such persons do any act to effect the object of the conspiracy, each shall be fined under this title or imprisoned not more than five years, or both.
If, however, the offense, the commission of which is the object of the conspiracy, is a misdemeanor only, the punishment for such conspiracy shall not exceed the maximum punishment provided for such misdemeanor.

NACDL Amicus Briefs
Mehanna v. United States, 1st Circuit, No. 12-1461; decision below, Criminal Action No. 09-10017-GAO, 2011 WL 3652524 (D. Mass. Aug. 19, 2011), brief filed 12/26/12. Conspiracy—Material Support—First Amendment---Petrozziello---Dellosantos. Amicus curiae brief of the National Association of Criminal Defense Lawyers in support of Appellant Tarek Mehanna and reversal of his conviction. Argument: “The district court misapplied First Circuit and United States Supreme Court conspiracy law. Moreover, these errors go not only to the heart of the substantive criminal law, but also to the First Amendment’s protection. From the scope of the indictment, through the court’s evidentiary rulings [admission of inflammatory evidence], and finally, its instructions, the result was a prosecution that effectively criminalized unpopular thought and expression unmoored from criminal conduct.” Authors: Nancy Gertner, Professor of Law at Harvard Law School, Cambridge, MA; David M. Porter, Sacramento, CA.; Steven R. Morrison, Assistant Professor at University of North Dakota School of Law, Grand Forks, ND.
Smith v. United States, U.S. Sup. Ct., No. 11-8976, case below 651 F3d 30, brief filed 8/27/12. Conspiracy—Defenses—Burden of Proof—Mens Rea. Amicus curiae brief of the National Association of Criminal Defense Lawyers. Argument: A defendant’s withdrawal from a conspiracy during the statute of limitations period negates an element of a conspiracy charge such that, once a defendant meets his burden of production that he did withdraw, the burden of proof rests with the government to prove beyond a reasonable doubt that he was a member of the conspiracy during the relevant period. The requirement that the prosecution prove the defendant’s guilt beyond a reasonable doubt is a defendant’s foremost safeguard against a wrongful conviction. The defendant’s withdrawal defense negated the “participation” element of the conspiracy, and relieving prosecutors of their burden to prove a defendant’s mental state substantially undermines the fairness of the trial by diluting one of the most important protections against wrongful convictions. Authors: Timothy P. O’Toole and Jeffrey Hahn, Miller & Chevalier, Chartered, Washington, DC.
