Notes of Advisory Committee on Proposed Rules

The rule is designed to afford the flexibility required in dealing with religious adults, atheists, conscientious objectors, mental defectives, and children. Affirmation is simply a solemn undertaking to tell the truth; no special verbal formula is required. As is true generally, affirmation is recognized by federal law. "Oath" includes affirmation, 1 U.S.C. §1; judges and clerks may administer oaths and affirmations, 28 U.S.C. §§459, 953; and affirmations are acceptable in lieu of oaths under Rule 43(d) of the Federal Rules of Civil Procedure. Perjury by a witness is a crime, 18 U.S.C. §1621.
