Functions of Court and Jury
When the admissibility of other evidence of contents of writings, recordings, or photographs under these rules depends upon the fulfillment of a condition of fact, the question whether the condition has been fulfilled is ordinarily for the court to determine in accordance with the provisions of Rule 104. However, when an issue is raised (a) whether the asserted writing ever existed, or (b) whether another writing, recording, or photograph produced at the trial is the original, or (c) whether other evidence of contents correctly reflects the contents, the issue is for the trier of fact to determine as in the case of other issues of fact.
Note (Federal Judicial Center)
The rule enacted by the Congress is the rule prescribed by the Supreme Court, amended by substituting "court" in place of "judge," and by adding at the end of the first sentence the phrase "in accordance with the provisions of Rule 104."
Advisory Committees Note
Most preliminary questions of fact in connection with applying the rule preferring the original as evidence of contents are for the judge, under the general principles announced in Rule 104, supra. Thus, the question whether the loss of the originals has been established, or of the fulfillment of other conditions specified in Rule 1004, supra, is for the judge. However, questions may arise which go beyond the mere administration of the rule preferring the original and into the merits of the controversy. For example, plaintiff offers secondary evidence of the contents of an alleged contract, after first introducing evidence of loss of the original, and defendant counters with evidence that no such contract was ever executed. If the judge decides that the contract was never executed and excludes the secondary evidence, the case is at an end without ever going to the jury on a central issue. Levin, Authentication and Content of Writings, 10 Rutgers L. Rev. 632, 644 (1956). The latter portion of the instant rule is designed to insure treatment of these situations as raising jury questions. The decision is not one for uncontrolled discretion of the jury but is subject to the control exercised generally by the judge over jury determinations. See Rule 104(b), supra.
