PHOENIX -- Democratic Arizona Gov. Katie Hobbs has relegated a Civil War-era ban on most abortions to the past by signing a repeal bill Thursday.

Hobbs says the move is just the beginning of a fight to protect reproductive health care in Arizona. But the repeal may not take effect until 90 days after the end of the legislative session, in June or July. Abortion rights advocates hope a court will step in to prevent that outcome.

The effort to repeal the long-dormant law, which bans all abortions except those done to save a patient's life, won final legislative approval Wednesday in a 16-14 vote of the Senate, as two GOP lawmakers joined with Democrats.

Hobbs denounced "a ban that was passed by 27 men before Arizona was even a state, at a time when America was at war over the right to own slaves, a time before women could even vote."

"This ban needs to be repealed, I said it in 2022 when Roe was overturned, and I said it again and again as governor," Hobbs said.

The vote extended for hours as senators described their motivations in personal, emotional and even biblical terms -- including graphic descriptions of abortion procedures and amplified audio recordings of a fetal heartbeat, along with warnings against the dangers of "legislating religious beliefs."

Democratic Arizona Attorney General Kris Mayes, an opponent of the near-total abortion ban, has said the earliest the dormant abortion-ban law could be enforced is June 27, though she has asked the state's highest court to block enforcement until sometime in late July. But the anti-abortion group defending the ban, Alliance Defending Freedom, maintains county prosecutors can begin enforcing it once the Supreme Court's decision becomes final, which hasn't yet occurred.

The near-total ban provides no exceptions for survivors of rape or incest. In a ruling last month, the Arizona Supreme Court suggested doctors could be prosecuted under the law first approved in 1864, which carries a sentence of two to five years in prison for anyone who assists in an abortion.

A repeal means that a 2022 statute banning the procedure after 15 weeks of pregnancy would become Arizona's prevailing abortion law.

A crowd of lawmakers -- mostly women -- joined the governor at the signing ceremony. Some were gripped by emotion as they cheered the repeal and said more is needed to protect rights to reproductive health care.

Former Democratic state Rep. Athena Salman celebrated approval of the repeal she initially proposed in 2019.

Arizona Rep. Stephanie Stahl Hamilton, a Democrat who was key in repealing the ban, said she spent her early years on the Navajo Nation where her parents were schoolteachers and saw firsthand people being denied reproductive rights. The main health care option on the reservation is the Indian Health Service, which operates under the Hyde Amendment that bars the use of federal funding for abortions except in cases of rape, incest or threats to the patient's life.

She said she also watched her sister-in-law struggle with two difficult pregnancies, one that resulted in a stillbirth and a nonviable one in which "they had to make the heartbreaking decision to terminate that pregnancy, because there was no brain development."
