Full Text of 735 ILCS 5/1-103
Plain-English Summary
This Code, like most statutes, is organized with headings above its Articles, Parts, and Sections. This section makes clear those headings carry no legal weight of their own. A heading cannot govern, limit, modify, or in any manner affect the scope, meaning, or intent of the provisions underneath it.
That leaves the headings as navigation aids rather than substantive text. A reader can rely on a heading to find the right provision, but not to argue that the heading narrows or expands what the text underneath says.
The rule reaches every level of heading used in the Code, from Article titles down to individual Section headings, and it applies whether the argument is that a heading should narrow a provision or broaden it.
Frequently Asked Questions
Can a court read a section's heading to help interpret its text?
No. The section says headings cannot govern, limit, modify, or affect the scope, meaning, or intent of any Article, Part, or Section.
Why include headings if they carry no legal weight?
The section does not say why, but headings still work as signposts for locating provisions, even though this Section keeps them from adding or subtracting from the text.
Does this rule apply only to Section headings?
No. It covers Article headings and Part headings as well as Section headings.
Could an ambiguous section be resolved by looking at its heading?
Under this section, no. A heading cannot affect scope, meaning, or intent, so any ambiguity has to be resolved from the text itself.
Is this section itself a rule of conduct?
No. It is a rule of interpretation directed at courts and readers, not a rule regulating how anyone must act.
