In one sentenceRule 364 requires parties to redact Social Security numbers, account numbers, and other personal identifiers before filing documents with a reviewing court.
Full Text of Ill. S. Ct. R. 364
(b) Personal identifiers, for purposes of this rule, are defined as follows:
(1) Social Security and individual taxpayer-identification numbers;
(2) driver’s license and state identification card numbers;
(3) financial account numbers;
(4) debit and credit card numbers; and
(5) for a juvenile or recipient of mental health services involved in a proceeding referenced in Rule 341(f), the name of the individual.
(c) The filing of a document containing personal identifiers is permissible if redacted to only
include:
(1) the last four digits of the Social Security or individual taxpayer-identification number;
(2) the last four digits of the driver’s license or state identification card number;
(3) the last four digits of the financial account number;
(4) the last four digits of the debit and credit card number; and
(5) in appeals filed from proceedings referenced in Rule 341(f), rather than redaction, the
respective juvenile or recipient of mental health services shall be identified by first name and last initial, except that initials only shall be used when, due to an unusual first name or spelling, using the first name and last initial would create a substantial risk of revealing the individual's identity.
(d) When the filing of personal identifiers is required by law, ordered by the court, or otherwise necessary to effect disposition of a matter, the party filing the document shall file a “Notice of Confidential Information Within Court Filing,” prepared by utilizing, or substantially adopting the appearance and content of, the form provided in the Article III Forms Appendix. Proof of service, as provided by Rule 12, shall be filed with the notice. The notice shall contain the personal identifiers in issue, and shall be filed under seal by the clerk immediately upon filing. Thereafter, the notice and any attachments thereto shall remain under seal and not available for public access, except as the court or a justice thereof may order. After the notice containing the personal identifier has been filed under seal, subsequent documents filed in the case shall include only redacted personal identifiers and, if necessary, appropriate reference to the sealed document containing the personal identifier.
If any of the personal identifiers in the sealed filing subsequently requires amendment or updating, the responsible party shall file the amended or additional information by filing an amended “Notice of Confidential Information Within Court Filing.”
(e) The clerk of the reviewing court is not required to review documents or exhibits for compliance with this rule.
(f) If a document or exhibit is filed containing personal identifiers, a party or any other person whose information has been included may file a motion pursuant to Rule 361 requesting that the court order redaction or the proper designation pursuant to this rule. The motion shall be filed under seal, and the clerk of the reviewing court shall remove the document or exhibit containing the personal identifier from public access pending the court’s ruling on the motion. A motion requesting redaction or the proper designation pursuant to this rule shall have attached a copy of the redacted version of the document. If the court or a judge thereof allows the motion, the clerk shall retain the unredacted copy under seal and the redacted copy shall become available for public access.
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.
Frequently Asked Questions
What personal identifiers does Rule 364 protect?
Social Security and taxpayer ID numbers, driver's license and state ID numbers, financial account numbers, and debit or credit card numbers, plus the names of juveniles or mental health service recipients in certain appeals.
How much of a protected number can appear in a filed document?
Only the last four digits, unless the full identifier is required by law, ordered by the court, or otherwise necessary to resolve the case.
What happens when the full identifier has to be filed somewhere?
It goes into a separate, sealed "Notice of Confidential Information Within Court Filing," and later filings reference that sealed notice instead of repeating the identifier.
Does the clerk check every filing to make sure identifiers are redacted?
No. The clerk isn't required to review documents or exhibits for compliance with this rule.
What can someone do if an identifier is filed unredacted?
File a sealed motion under Rule 361 asking the court to order redaction or the proper designation; the clerk removes the document from public access while the motion is pending.
