Which qualifications and court directions matter?

The rule does not cover every civil case: Rule 222(a) covers mandatory arbitration and stated money-damages or tax-collection cases up to $50,000. It excludes small claims, ordinance violations, 750 ILCS family actions and equitable relief. Paragraph (j) permits additional local case categories.
Local timing and actual changes come first: Rule 222(c) applies the local timeline before its 120-day fallback. Party agreement or a court direction for good cause can change timing. A responsive pleading’s allowed due date is not its actual filing date.
Sworn completeness and continuing disclosure matter: Paragraphs (c), (d) and (e) require information within possession, custody or control and obtainable by reasonable inquiry, written disclosure and an accompanying affidavit. Prompt filed notice and seasonable supplementation are separate duties. Paragraph (g) addresses exclusion of untimely evidence, subject to good-cause leave.
