Whoever, being an officer or employee of the United States, knowingly contracts for the erection, repair, or furnishing of any public building, or for any public improvement, to pay a larger amount than the specific sum appropriated for such purpose, shall be fined under this title  or imprisoned not more than one year, or both.
18 U.S. Code § 435. Contracts in excess of specific appropriation
Words “or employee” were inserted to remove any ambiguity as to scope of section.
The offense described in this section involves no moral turpitude, and therefore the punishment provisions were reduced from $2,000 to $1,000 and from 2 years to 1 year, so that the stigma of a felony would not attach to an offender. (See classification of felony and misdemeanor in section 1 of this title and note thereunder.)
Mandatory punishment provisions were rephrased in the alternative.
Changes were also made in phraseology.
1994—Pub. L. 103–322, which directed the amendment of this section by substituting “fined under this title” for “fined not more than $5,000”, was executed by making the substitution for “fined not more than $1,000”, to reflect the probable intent of Congress.
