Full Text of Ill. S. Ct. R. 364
Plain-English Summary
Filed court documents become part of the public record, so Rule 364 keeps certain personal details out of them. It covers Social Security and taxpayer ID numbers, driver's license and state ID numbers, financial account numbers, and debit or credit card numbers. In appeals involving juveniles or recipients of mental health services, it also covers the person's full name.
Instead of the full number, a filed document may show only the last four digits, and a juvenile or mental-health patient is identified by first name and last initial (or initials alone, if that first name is unusual enough to give the person away). When the full identifier has to appear somewhere — because the law requires it, the court orders it, or the case can't be resolved without it — the filer submits it separately in a sealed "Notice of Confidential Information Within Court Filing," and every later filing in the case refers back to that sealed notice instead of repeating the identifier.
The clerk isn't obligated to check every filing for compliance, so the burden falls on the filer. If an unredacted identifier does slip through, anyone affected — not just a party — can file a sealed motion asking the court to order redaction, and the clerk pulls the document from public view while that motion is pending.
