ADVISORY COMMITTEE NOTE

This rule is the federal rule, verbatim. The oath or affirmation need not be in any special form but only such as to awaken the conscience of the witness and impress the witness with the duty to testify truthfully. The rule is a modified version of Rule 18, Utah Rules of Evidence (1971).
