United States v. Scholle & the Introduction of Computer Evidence


If your firm is introducing computer evidence in court, be aware that a stronger foundation may be required for computer evidence than regular business records. Part of the basis for this is a decision by the 8th Circuit, United States v. Scholle, 553 F.2d 1109 (8th Cir. 1977). In this admittedly ancient decision (in terms of digital technology) the court found that a party presenting computer evidence has to show evidence of how data for its system was collected, how the data is maintained in the system, and how the extracted data to be presented was retrieved. The Scholle standard calls for a "more comprehensive foundation".

Scholle concerned "novel evidence of a computer printout representing a compilation of information concerning cocaine exhibits" from the DEA that was presented in a case brought against defendants charged with importing and distributing cocaine. The computer records showed that there was an unusual chemical in the cocaine. They came from the System to Retrieve Information from Drug Evidence (STRIDE) which held data on drug samples analyzed by several DEA labs in the United States. Evidence of benzocaine in both cocaine seized by one party importing it, and another party distributing it, was presented to show a chain of conspiracy.

The court acknowledged that a judge has broad discretion to determine the relevancy of computer evidence and noted that FRE 803(6) specifically included "data compilations" in the category of records which can be admitted without the testimony of the person who prepared them when they are made in contemporaneously in the regular course of business. The court held that:

"Even where the procedure and motive for keeping business records provide a check on their trustworthiness (United States v. Fendley, supra), the complex nature of computer storage calls for a more comprehensive foundation. Assuming properly functioning equipment is used, there must be not only a showing that the requirements of the Business Records Act have been satisfied, but in addition the original source of the computer program must be delineated, and the procedures for input control including tests used to assure accuracy and reliability must be presented. "

While the Court of Appeals held that the District Court did not err in admitting the evidence from the STRIDE system, it criticized the weak foundation for the evidence. While the originator of the system testified adequately about the source of the data in the system, no evidence was shown about the procedure for confirming the reliability of its input into the system.

"In evaluating the admission of the disputed printout, we must consider the reliability of what goes into the computer as well as the reliability of what comes out."

While there have been later Court of Appeals decisions holding that computer records should be treated like any other evidence, it remains advisable to follow the Scholle standard. See the Wikipedia article on Digital Evidence.
