Background
Anne Pramaggiore, CEO of Commonwealth Edison Company, and Michael F. McClain, a ComEd lobbyist, were convicted of conspiracy, offering things of value to Illinois House Speaker Michael Madigan, and falsifying corporate books and records in violation of the Foreign Corrupt Practices Act. The government alleged they structured illegal subcontracting and no-show consulting contracts to conceal payments to Madigan’s associates—totaling over $1.3 million over eight years—in exchange for favorable legislation. The conspiracy indictment charged four objects: violating 18 U.S.C. § 666(a)(1)(B) and (a)(2) (unlawful gratuities and bribes to state officials) and violating the FCPA by falsifying books/records and circumventing accounting controls.
The jury returned a general verdict convicting on all counts. However, after trial, the Supreme Court decided Snyder v. United States (2024), narrowing § 666 to punish only quid pro quo bribery, not illegal gratuities. The district court vacated the substantive § 666 convictions but upheld the conspiracy convictions, holding any error harmless because valid FCPA-based conspiracy grounds remained.
The Court’s Holding
The Seventh Circuit reversed and vacated the conspiracy and FCPA convictions. Following precedent rooted in Stromberg v. California and Yates v. United States, when a jury returns a general verdict on a multi-object conspiracy and one or more objects become legally invalid, the conviction cannot stand unless harmless error analysis shows the jury must have convicted on valid grounds. The court held error was not harmless because: (1) the jury gave a general verdict with no indication which conspiracy object(s) it relied upon; (2) the evidence supporting conspiracy to pay gratuities was not coextensive with evidence supporting conspiracy to violate the FCPA; and (3) the court cannot know whether the jury convicted based on invalid § 666 theories, valid FCPA theories, or both.
Similarly, the FCPA convictions were vacated because the government used a Pinkerton instruction allowing conviction if co-conspirators committed the substantive crimes in furtherance of the conspiracy. Since the jury may not have found a valid conspiracy, it might have convicted Pramaggiore and McClain based on the legally invalid conspiracy ground alone. The court rejected their Thompson v. United States argument that “falsify” excludes misleading documents, finding sufficient evidence that the contracts and records were actually false rather than merely misleading, and therefore affirmed that acquittal was unwarranted. Retrial remains available to the government if it chooses to proceed.
Key Takeaways
- General verdicts on multi-object conspiracies with both valid and invalid legal theories require vacatur when evidence is not coextensive and harmlessness cannot be demonstrated.
- Post-conviction Supreme Court decisions narrowing criminal statutes can render prior jury instructions legally flawed, triggering reversal and remand for retrial rather than acquittal.
- The Seventh Circuit applies a strict harmless error test requiring proof that the jury must have convicted on valid grounds; speculation or “overwhelming evidence” alone cannot cure error when jury intent is unknowable.
- Pinkerton conspiracy liability requires a valid underlying conspiracy; if that conspiracy rests on invalid legal theories, resulting substantive convictions must be vacated.
Why It Matters
This decision reinforces the Seventh Circuit’s protective approach to general verdicts in multi-theory prosecutions, applied here in the context of Snyder’s post-conviction narrowing of § 666. Prosecutors relying on multiple alternative legal theories must ensure either that a special verdict permits identification of which ground the jury chose, or that the evidence is so thoroughly coextensive that conviction on one theory necessarily implies conviction on others. The ruling also clarifies that Thompson’s distinction between “false” and “misleading” applies to FCPA falsification charges—though here the defendants failed to establish that the documents were merely misleading rather than affirmatively false.
For defendants, the decision confirms that vacatur for legal error does not preclude retrial; jeopardy does not attach on appeal, and the government may prosecute again with corrected jury instructions. For the prosecution, it underscores the importance of reconsidering charging theories in light of adverse Supreme Court decisions and of structuring verdicts to permit appellate review of which grounds the jury actually relied upon.
