===Affirmation by the Supreme Court===
Over the years there have been many court cases in which the Supreme Court has played its part. The ''SEC v. Chenery Corp'' case<ref name="Heritage" /> is often referenced in regard to administrative law. But well before ''Chenery'' the Supreme Court affirmed the actual existence of administrative agencies, in the ''[[J. W. Hampton, Jr. & Co. v. United States]]'' case.<ref>{{cite web |url=https://supreme.justia.com/cases/federal/us/276/394/case.html |title=J. W. Hampton, Jr. & Co. v. United States |date=April 9, 1928 }}</ref>
In the ''Hampton'' case, the court held that:
<blockquote>If Congress shall lay down by legislative act an intelligible principle to which the person or body authorized to [exercise the delegated authority] is directed to conform, such legislative action is not a forbidden delegation of legislative power. If it is thought wise to vary the customs duties according to changing conditions of production at home and abroad, it may authorize the Chief Executive to carry out this purpose, with the advisory assistance of a Tariff Commission appointed under congressional authority.</blockquote>
