Courts at the city, county, regional, state, and federal levels heard cases involving St. Clair’s residents.
Cases ranged from childhood guardianship appointments, divorce, and indigent care, to naturalization and criminal cases, for example.
In the county’s formative years, the County Commissioners/board of supervisors created and named new townships, approved ferry rates, and changed the boundaries of road districts. Judges of the local court heard cases about vagabonds, limited criminal offenses, and legal disputes involving monetary damages under the legal limit, for example.¹ The County Courts created during the territorial period lasted until 1964.² Read about the various courts and records each kept at the Illinois Regional Archives Depository website.
