Business records exception
The business records exception to the U.S. hearsay rule is based on Rule 803 of the Federal Rules of Evidence. It is sometimes referred to as the business entry rule.
Rationale
The basic rationale for the exception is that employees are under a duty to be accurate in observing, reporting, and recording business facts. The underlying belief is that special reliability is provided by the regularity with which the records are made and kept, as well as the incentive of employees to keep accurate records. The exception functions to allow the record to substitute for the in-court testimony of the employees, but it can only substitute for what the employee could testify about. The availability of the declarant is immaterial for the purposes of this exception.Reliability of the statements in the record
It must be apparent to the judge that the record was made in the regular course of business, i.e., that it was customary practice to make such an entry and that the entrant had a duty to record it. The record must have been made at or near the time of the act, event, or transaction at issue. Furthermore, the record must consist of matters either within the personal knowledge of the entrant or within the personal knowledge of someone with a duty to transmit the information to the entrant.This last point was contested in the case of Johnson v. Lutz, 253 N.Y. 124, 170 N.E. 517, which held that a business record is admissible only when it is made by an employee about information, obtained by him, from an informant who himself was under a business duty to impart that information. Johnson dealt specifically with the admissibility of police reports, and set a limitation on the use of such reports in court. Even though the police officer was under a duty to properly record the statements of an informant, the informant himself was under no duty to report the events correctly, and therefore the informant's statement was still inadmissible hearsay.
