Rule 1008 Functions of Court and Jury

Sometimes a person wants to use a copy or other secondary evidence instead of an original document, recording, or photo. Before that copy can be allowed into evidence, certain conditions usually have to be met. Normally, the judge decides whether those conditions have been satisfied. This is a standard job for the judge, not the jury, and it works the same way as other preliminary questions about evidence.

But there are three specific questions that belong to the jury instead. If there's a dispute about whether the original document, recording, or photo ever really existed, the jury decides that. If there's a question about whether something presented at trial is actually the real original, the jury decides that too. And if people disagree about whether other evidence accurately shows what the original said or contained, the jury settles that dispute as well.

The idea behind this rule is to divide up responsibility fairly. The judge handles the technical, legal questions about whether evidence can be used at all. But when the dispute is really about the facts, like whether something existed or whether a copy is accurate, that's the kind of decision juries are meant to make. This keeps the jury in charge of weighing evidence and deciding what actually happened, while the judge keeps control over the legal rules for what evidence gets in front of the jury in the first place.
