Arizona House advances multiple Senate bills to third reading, rejects stem-cell regulatory bill then votes to reconsider

The Arizona House met in committee of the whole on April 21 and advanced a slate of Senate bills to third reading, while members engaged in pointed debate over measures involving immigration reporting and the scope of foreign or religious law in state court.

The session opened with ceremonial business and a proclamation honoring the East Valley Hispanic Chamber of Commerce; committees then reported a series of Senate bills to the floor with committee amendments adopted as offered. Majority Leader Carbone moved adoption of the committee reports and the House placed multiple measures on third reading.

On the floor, members debated SB 10 55, a public-safety bill that, according to opponents, would require law-enforcement reporting to federal immigration authorities in situations where an arrestee is suspected of being unlawfully present. The minority whip (identified in the record as the Minority Whip) said, “My biggest concern is that… this bill, as written, would require reporting to ICE… anyone who you suspect might be here unlawfully,” and warned that vague standards for “suspicions” could enable profiling. Representative Pamela Carter responded that the bill as written would notify federal authorities only when a person arrested for a crime cannot prove legal presence and that it was intended to enforce federal law in those circumstances.

Another contested measure, SB 15 73, drew an extended exchange about whether state law already bars courts from enforcing foreign or sectarian law. Minority Leader De Los Santos criticized the bill as unnecessary and costly, saying in floor remarks that the proposal was “a shocking waste of time” because statutes already prohibit enforcement of foreign law. Supporters argued the bill clarified the state courts’ obligations; the chair ruled points of order out of order and recognized continued debate.

On third reading votes, the House approved several bills sent from the Senate. Recorded results included: - SB 11 68 (dentistry-related amendments): passed 43 ayes, 11 nays, 5 not voting, 1 vacant. - SB 11 72 (changes related to the Department of Economic Security): passed 54 ayes, 1 nay, 4 not voting, 1 vacant. - SB 12 90 (planned communities statute, as amended): recorded as passed following roll-call and explanation-of-vote remarks by members concerned about homeowners association meetings and senior safety.

Senate Bill 12 14, described on the floor as a regulatory framework for stem-cell regenerative therapies, failed on third reading. Representative Bliss, a sponsor/advocate in the record, said the bill would “provide for patient safety” and create guardrails for therapies she described as currently unregulated; other members said they had not reached comfort with the bill’s implications. The clerk recorded a final tally of 25 ayes, 31 nays, 3 not voting, and 1 vacant, and the measure failed. Representative Martinez then moved — and the House adopted — a motion to reconsider that failure, placing SB 12 14 back on the third-reading order.

Procedural items and additional third-reading votes followed (for example, SB 12 21 passed 32–24). The House concluded with brief announcements and adjourned until 10 a.m. on April 22, 2026.

What’s next: several measures advanced in committee of the whole now proceed to formal third-reading consideration as designated; SB 12 14 will return to the floor under the motion to reconsider. The clerk will transmit passed measures to the Senate as provided in the journal.
