Effective beginning the next term of office of the Sheriff of Cullman County after the ratification of this amendment, any allowances or other amounts received by the sheriff for feeding prisoners shall be deposited in a separate account in the county treasury to be known as the "Sheriff's Discretionary Fund" and shall be used by the sheriff for the feeding of prisoners in the county jail. Any funds in the Sheriff's Discretionary Fund over the amounts needed for feeding prisoners may be used by the sheriff for law enforcement purposes and for the operation of the office of the sheriff. Any funds in the Sheriff's Discretionary Fund shall be carried over from year to year. In the event additional amounts are needed by the sheriff for the feeding of prisoners, the amounts shall be paid by the sheriff from any other discretionary funds available for the operation of the office of the sheriff. The sheriff shall not be subject to the competitive bid law for the purchase of food or supplies used for feeding prisoners in the county jail. Also, effective at that time, the sheriff shall receive an annual salary equal to the annual salary of the Judge of Probate of Cullman County not to include any compensation received by the judge of probate for election purposes.
