In each county there is a county court with limited jurisdiction in both civil and criminal matters. The county courts are authorized to try criminal cases upon information, of the grade of misdemeanors only. And indictments for misdemeanors may be transferred from the circuit courts to the county courts in the respective counties, for trial, except in Cook County; and the cases thus transferred by proper order of the court shall be tried as though originally commenced in those courts by the filing of informations. The municipal court of the city of Chicago is a court of limited criminal as well as civil jurisdiction. Informations for misdemeanors may be filed in that court the same as in the county courts. The said municipal court is also authorized to try felony cases when properly transferred to it from the criminal court of Cook County, that is, any felony alleged to have been committed in the City of Chicago. Justices of the peace are authorized to try and dispose of small misdemeanors where the punishment is a fine only, not exceeding a specified amount; in Illinois the limit is two hundred dollars. Justices of the peace may inflict the punishment of imprisonment in the county jail if authorized by law.
