Griffin v. United States

Background

A defendant, Diane Griffin, was tried on a 23-count indictment and named in one count accusing her of conspiring with two others to defraud federal agencies. The single conspiracy count alleged two objects: one to impair the Internal Revenue Service’s ability to learn about taxes and another to impair the Drug Enforcement Administration’s ability to locate forfeitable assets. Trial evidence tied Griffin to the IRS objective but not to the DEA objective because a key witness did not testify. The trial court denied Griffin’s requests for severance, special jury questions, and an instruction limiting conviction to the IRS object. The jury returned a general guilty verdict on the conspiracy count.

Reasoning

The Court asked whether a general guilty verdict must be set aside when evidence fails for one of several alleged objects. It reviewed prior cases and concluded longstanding practice and precedent permit a general verdict to stand if it is legally supportable on any submitted ground. The Court distinguished earlier cases that required reversal when a jury could have convicted based on an unconstitutional or legally deficient ground. Relying on Turner and other authorities, the Court held that when one alleged object is supported by adequate evidence, a general conviction need not be overturned because other alleged objects lacked support. The Court affirmed the Seventh Circuit’s decision.

Real world impact

The ruling means many conspiracy convictions will stand if juries had sufficient evidence on at least one alleged objective. Trial judges retain discretion to remove unsupported theories or to give special interrogatories, and prosecutors can avoid risk by charging separately or using clear jury questions.

Dissents or concurrances

Justice Blackmun agreed with the outcome but warned about jury confusion in complex indictments and urged use of separate counts or special interrogatories to avoid unfair results.
