Search 31 U.S.C. § 1347 : US Code - Section 1347: Appropriations or authorizations required for agencies in existence for more than one year

(a) An agency in existence for more than one year may not use
amounts otherwise available for obligation to pay its expenses
without a specific appropriation or specific authorization by law.
If the principal duties and powers of the agency are substantially
the same as or similar to the duties and powers of an agency
established by executive order, the agency established later is
deemed to have been in existence from the date the agency
established by the order came into existence.
(b) Except as specifically authorized by law, another agency may
not use amounts available for obligation to pay expenses to carry
out duties and powers substantially the same as or similar to the
principal duties and powers of an agency that is prohibited from
using amounts under this section.
