Senator urges voter amendment to define ‘person’ as any human with unique DNA; debate centers on SJR 72

The Missouri Senate heard extended floor debate on Senate Joint Resolution 72, which would send a proposed constitutional amendment to the ballot to define “person” as “every human being with a unique DNA code from fertilization until birth.” Senator from Lawrence, who read the committee substitute and spoke at length in favor, framed the measure as a voters’ choice on whether the state should recognize unborn life under the Missouri Constitution.

Senator from Lawrence read the proposed addition aloud and urged colleagues to let voters decide: "That the term person under this constitution includes every human being with a unique DNA code, regardless of age, including every human child at every stage of biological development," he said, calling the change a moral duty and arguing that science links DNA uniqueness to personhood. He also noted the official fiscal summary included with the resolution that the measure "is expected to have no fiscal note or no fiscal impact."

Supporters told the Senate they view the measure as a way to provide constitutional protections for developing human life and to align state law and statute language. The sponsor said some statutes already state life begins at conception but are inconsistent with other constitutional provisions and with the voter-approved 2024 section protecting reproductive freedom; he described legal conflicts that, in his view, could be resolved only by a constitutional amendment and, if necessary, later litigation.

Opponents and some questioners on the floor warned that the proposal raises immediate legal uncertainty because it would potentially conflict with the 2024 voter-approved provision on reproductive freedom and with existing statutes; they pressed for clearer drafting, asked about the practical effects on health-care delivery, criminal law, and enforcement, and queried the decision to bring the measure late in the session. One senator noted the procedural obstacles in getting controversial measures to a vote in the closing hours of the session and suggested a slower timetable for a change as consequential as a constitutional amendment.

The resolution was read and debated on the floor; senators discussed how such a ballot question would be captioned, the governor’s ability to schedule an election, and the likelihood of extended floor activity or filibusters if the measure is considered formally. The Senate did not adopt a final passage vote on SJR 72 during the segment recorded in the transcript; the sponsor said he would continue to press for consideration and to ask Republican senators for their explicit positions, and he predicted sustained debate if the body takes the measure up later.
