The Legal Principle
This section distills the key legal rule established or applied by the court—the one-liner you'll want to remember for exams.
Facts:
- Frank Costello was investigated for wilfully attempting to evade payment of federal income taxes for the years 1947, 1948, and 1949.
- The government alleged that Costello and his wife had fraudulently underreported their income during those years.
- A federal grand jury was convened to hear evidence regarding the tax evasion allegations.
- The only witnesses who testified before the grand jury were three government investigating officers.
- These officers did not have any firsthand knowledge of the financial transactions in question.
- Their testimony consisted of summaries of financial documents and information obtained from other potential witnesses, which constituted hearsay.
- Based exclusively on this hearsay testimony, the grand jury returned an indictment charging Costello with tax evasion.
