JCAB (Joint Committee on Appropriations and Budget) is a committee governed by separate rules from most legislative committees. It is typically used as a way for House and Senate leadership to introduce and approve new bills in the final weeks of the legislative session.
The committee, which is co-chaired by the Chairs of the House and Senate Appropriations committees, is not subject to regular legislative deadlines. Only bills authored by the Appropriations Chairs or by the House Speaker and Senate President Pro Tem can be referred to JCAB. House and Senate JCAB can meet together, but most often meet separately. Most appropriation bills are assigned to JCAB, but substantive bills can also be heard. Bills are required to have a fiscal impact statement to pass out of JCAB. Bills that pass out of JCAB are placed on a separate Joint Calendar to be heard by their full chambers for Third and Final Reading.
