Brief

Facts

Walter and Daniel Pinkerton were brothers who lived a short distance from each other on Daniel’s farm. They were indicted for violations of the Internal Revenue Code on ten substantive counts and one conspiracy count. A single conspiracy was charged and proved. Some of the overt acts charged in the conspiracy count were the same acts charged in the substantive counts, and each substantive offense found was committed pursuant to the conspiracy. Walter committed the substantive offenses. There was no evidence that Daniel participated directly in them, and no evidence of affirmative action by him to withdraw from the conspiracy. He was not indicted as an aider or abettor, and his case did not go to the jury on that theory. Instead, the jury could convict each brother of the substantive offenses if the two were then parties to an unlawful conspiracy and the offenses were done in furtherance of it. The jury found Walter guilty on nine substantive counts and on the conspiracy count. It found Daniel guilty on six substantive counts and on the conspiracy count. Walter was fined $500 and got thirty months on the substantive counts, plus a concurrent two-year conspiracy sentence. Daniel was fined $1,000 and got thirty months on the substantive counts, plus a $500 fine and a concurrent two-year conspiracy sentence. Justice Rutledge’s dissent adds that the agreement concerned whiskey offenses in fraud of the federal revenues, and that Daniel was in the penitentiary when some of Walter’s crimes were done.

Issues

  1. Do the substantive offenses merge into the conspiracy count, so that only a single conspiracy sentence may be imposed, when each was committed pursuant to the conspiracy and some were also charged as overt acts?
  2. Can a party to a continuous conspiracy be convicted of substantive offenses committed by a co-conspirator in furtherance of the unlawful agreement, where the defendant did not directly participate in the substantive crimes and did not withdraw from the conspiracy?

Holding

The substantive offenses did not merge into the conspiracy count, so convictions and sentences on both were lawful. Although there was no evidence that Daniel directly participated in Walter's substantive crimes, he was a party to a continuous conspiracy, there was no evidence of affirmative action by him to withdraw, and Walter committed the offenses in furtherance of it, so Daniel was properly convicted of them.
