Rule 106. Remainder of or related writings or recorded statements.
When a writing or recorded statement or part thereof is introduced by a party, an adverse party may require the introduction at that time of any other part or any other writing or recorded statement which ought in fairness to be considered contemporaneously with it.
ADVISORY COMMITTEE NOTE
This rule is the federal rule, verbatim. Utah Rules of Evidence (1971) was not as specific, but Rule 106 is otherwise in accord with Utah practice.
