Harold Hitz Burton,
Curcio v. United States — Opinion of the Court
“ The custodian's act of producing books or records in response to a subpoena duces tecum is itself a representation that the documents produced are those demanded by the subpoena. Requiring the custodian to identify or authenticate the documents for admission in evidence merely makes explicit what is implicit in the production itself. The custodian is subjected to little, if any, further danger of incrimination. ”
