NRS 52.295: Functions of judge and jury.

1. Except as otherwise provided in subsection 2, when the admissibility of other evidence of contents under these rules depends upon the fulfillment of a condition of fact, the question whether the condition has been fulfilled is for the judge to determine.

2. When an issue is raised:

(a) Whether the asserted writing ever existed;

(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,

Ê the issue is for the trier of fact to determine as in the case of other issues of fact.
