§ 43. Specific appropriations limited as to use; certain
appropriations to be specific. Money appropriated for a specific purpose
shall not be used for any other purpose, and the comptroller shall not
draw a warrant for the payment of any sum appropriated, unless it
clearly appears from the detailed statement presented to him by the
person demanding the same as required by this chapter, that the purposes
for which such money is demanded are those for which it was
appropriated. The comptroller shall not audit any claim for salary,
labor or wages, unless an appropriation applicable thereto has been
already made specifying the amount thereof appropriated for such
purpose.

Except as otherwise expressly provided, the comptroller shall not
audit any claim or account or draw a warrant for the payment of moneys
for the purchase of an aircraft intended primarily for the purpose of
carrying passengers or the rent of an aircraft for such purpose for a
period longer than ten days. The provision of this section shall not
apply to the necessary rental of automobiles for construction and
maintenance work on the highways of the state or for grade crossing
elimination work.
