As previously stated, the interpretations of the law contained in
this part are official interpretations. So long as they remain effective
and are not modified, amended, rescinded or determined by judicial
authority to be incorrect, they may be relied upon as provided in
section 10 of the Portal-to-Portal Act of 1947 (63 Stat. 910, 29 U.S.C.
251 et seq., discussed in part 790 of this chapter). In addition, the
Supreme Court has recognized that such interpretations of this Act
``provide a practical guide to employers and employees as to how the
office representing the public interest in its enforcement will seek to
apply it'' and ``constitute a body of experience and informed judgment
to which courts and litigants may properly resort for guidance.''
Further, as stated by the Court: ``Good administration of the Act and
good judicial administration alike require that the standards of public
enforcement and those for determining private rights shall be at
variance only where justified by very good reasons.'' (Skidmore v.
Swift, 323 U.S. 134).
