A judicial officer with limited power whose duties may include hearing cases that involve civil controversies, conserving the peace, performing judicial acts, hearing minor criminal complaints, and committing offenders. Justices of the peace are regarded as civil public officers, distinct from peace or police officers.
The county sheriff is the sheriff of the courts, maintains public peace, and has custody of the county jail. As chief enforcement officer of the circuit courts, the sheriff's office, which includes the sheriff and deputies, is charged by constitutional and statutory laws with the execution of summons, enforcement of judgments, orders, injunctions, garnishments, attachments, and the making of arrests on warrants issued by the courts. The sheriff also opens and attends each term of circuit court, notifies residents selected to jury duty and assists in handling witnesses and prisoners during a given court term. The county collector is the collector of taxes for the county and collects municipal, county, school and improvement district taxes and turns them over to the county treasurer.
The county treasurer is the disbursement officer of the county, and is the unofficial or quasi comptroller. A few counties do have a county comptroller. The treasurer is responsible for the custody and disbursement of all county funds and school district funds. The treasurer, therefore, receives county property tax collections, county sales tax collections, county turnback funds, grant funds, fees and fines from other county officials and departments, and revenues from various other sources. The treasurer, after receiving this revenue, distributes the money to the various taxing entities and the other units of the county. The county treasurer signs checks, prepared and signed by the county clerk indicating that the expenditure has been authorized by the county court, to pay employees and creditors of the county.
The County Courts shall have exclusive original jurisdiction in all matters relating to county taxes, roads, bridges, ferries, paupers, bastardy, vagrants, the apprenticeship of minors, the disbursement of money for county purposes, and in every other case that may be necessary to the internal improvement and local concerns of the respective counties.
