What is a committee hearing?
Committee hearings are a method by which committee members gather information on various legislative proposals or topics. Committees are categorized by subject area and legislation is usually assigned to the committee that can best assess the merits of the proposal. Below are the three types of committee hearings in the ILGA.
- Legislation only committee hearing: The committee meets only to review and vote on legislation.
- Subject Matter only committee hearing: The committee meets to discuss a specific topic and does not require a vote by committee members.
- Subject Matter with Legislation: The committee meets to both discuss a specific topic but will also vote on legislation that may or may not be related to the subject matter being discussed.
