Federal Reserve Act

Section 30. Saving clause

If any clause, sentence, paragraph, or part of this Act shall for any reason be adjudged by any court of competent jurisdiction to be invalid, such judgment shall not affect, impair, or invalidate the remainder of this Act, but shall be confined in its operation to the clause, sentence, paragraph, or part thereof directly involved in the controversy in which such judgment shall have been rendered.

[Omitted from U.S. Code. Part of original Federal Reserve Act; not amended.]
If this is the case, it would also seem to be that Amendments 9 and 10 of the Bill of Rights are also savings clauses
