The Illinois Supreme Court is the state's highest court and has jurisdiction over appeals from the appellate courts and certain direct appeals from circuit courts. It is responsible for supervising the administration of all Illinois courts, interpreting state laws and the Illinois Constitution, and regulating the legal profession in the state. Its decisions are binding on all other Illinois state courts.

Illinois Supreme Court Email Formats and Examples

The Illinois Supreme Court primarily conducts official communication through its Clerk's Office. Direct email addresses for individual Justices are generally not publicly available for case-related matters to maintain judicial impartiality and formal communication channels. For official filings and inquiries, the Supreme Court Clerk's office is the designated point of contact. Staff within the Administrative Office of the Illinois Courts (AOIC) may use formats like `[firstinitial][lastname]@illinoiscourts.gov` or `[first].[last]@illinoiscourts.gov`, but this is not standardized for all personnel, nor is it the method for contacting Justices regarding judicial matters.

No single, publicly disseminated email format for Justices. Contact via Supreme Court Clerk. For AOIC staff (not Justices): potentially `flastname@illinoiscourts.gov` or `firstname.lastname@illinoiscourts.gov`.
