The circuit courts are the highest common-law and equity courts of record exercising original jurisdiction within the State. Each has full common-law and equity powers and jurisdiction in all civil and criminal cases within its county, and all the additional powers and jurisdiction conferred by the Constitution and by law, except where by law jurisdiction has been limited or conferred exclusively upon another tribunal.
