Whether proof of two conspiracies, when the indictment charged one conspiracy, required reversal of Berger's conviction.
Holding
No. The variance was not fatal because, on this record, it did not affect Berger's substantial rights.
Reasoning
The Court rejected a rigid rule that proof of separate and disconnected conspiracies automatically defeats a conviction under an indictment alleging one larger conspiracy. Under the harmless-error provision in § 269 of the Judicial Code, the real question is whether the variance substantially injured the accused, not simply whether the indictment and proof differed in form.
The correspondence requirement protects two practical interests: giving the defendant adequate notice to prepare a defense without surprise, and preserving protection against a later prosecution for the same offense. A variance is material only when it threatens one of those interests.
Berger was connected by the evidence to the conspiracy involving Katz and Jones, and that conspiracy fell within the indictment's language. Although the government also offered evidence of the separate Rice-Katz conspiracy, Berger showed no reasonable basis to conclude that the additional proof surprised him, impaired his defense, or compromised his ability to invoke double jeopardy in a future prosecution.
The Court stressed that this kind of variance can be prejudicial in another case. But here, the fact that the evidence proved an additional conspiracy involving other defendants did not, by itself, make the variance fatal as to Berger.
