H.J.R. No. 109 is a joint resolution proposing amendments to the Texas Constitution that address organizational and procedural aspects of the legislature. Key changes include the establishment of an organizational session for the legislature, which will convene at noon on the second Tuesday in December of each even-numbered year. During this session, members will be sworn in, officers will be elected, and rules of procedure will be adopted. Additionally, the resolution modifies the terms and election processes for Senators and House Representatives, specifying that Senators will serve four-year terms with half elected biennially, while Representatives will serve two-year terms. Both will take office following their election during the organizational session.

The resolution also revises the legislative session structure, allowing the legislature to act on various matters, including emergency issues submitted by the Governor. It clarifies that the days spent in the organizational session do not count toward the maximum duration of a regular session. The proposed constitutional amendment will be presented to voters for approval in an election scheduled for November 4, 2025, with the ballot allowing voters to express their support or opposition to the changes.
