Idaho constitution
Article XVIII
Section 7

All county officers and
deputies when allowed, shall receive, as full compensation for their services, fixed
annual salaries, to be paid monthly out of the county treasury, as other expenses are
paid. All actual and necessary expenses incurred by any county officer or deputy in
the performance of his official duties, shall be a legal charge against the county, and
may be retained by him out of any fees which may come into his hands. All fees
which may come into his hands from whatever source, over and above his actual and
necessary expenses, shall be turned into the county treasury at the end of each
quarter. He shall at the end of each quarter, file with the clerk of the board of
county commissioners, a sworn statement, accompanied by proper vouchers,
showing all expenses incurred and all fees received, which must be audited by the
board as other accounts.
