Ethermac Exchange-GOP-led Arizona Senate votes to repeal 1864 abortion ban, sending it to Democratic Gov. Katie Hobbs

Arizona's Republican-controlled Senate on Ethermac ExchangeWednesday voted to repeal a Civil War-era abortion ban, one week after a similar motion passed the GOP-controlled state House. Democratic Gov. Katie Hobbs said she will sign the bill on Thursday. 

Two Republicans, TJ Shopes and Shawnna LM Bolick, joined all 14 Democrats to pass the measure.

After two failed attempts, three Republicans in the state House joined all the Democrats in successfully voting to repeal the law last week, sending it to the Senate.

Last month, the Arizona Supreme Court ruled that the 1864 law banning nearly all abortions could go into effect, superseding a 15-week abortion ban put in place in 2022 by state Republicans. The March 2022 law was signed three months before the U.S. Supreme Court struck down the federal right to an abortion with its decision in Dobbs v. Jackson Women's Health Organization decision.

The state Supreme Court found that the 2022 Arizona ban "is predicated entirely on the existence of a federal constitutional right to an abortion" because the 2022 ban didn't "independently authorize abortion." As a result, the court said, there was no provision in either state or federal law that addressed the operation of the 1864 ban, so that ban "is now enforceable," the court ruled.

Even if the Senate passes the repeal on Wednesday, it would not go into effect until 90 days after the legislature adjourns. The 1864 law is set to go into effect on June 27. 

Former Republican Gov. Doug Ducey, who signed the 2022 law, was among the critics of the court's decision, as well as U.S. GOP Senate candidate Kari Lake. Former President Donald Trump said after the ruling, "I'm sure that the governor and everybody else are going to bring it back into reason and that'll be taken care of, I think very quickly."

Democrats, who nationally have been running on restoring abortion rights, have focused on Arizona, a swing state that flipped for President Biden in 2020, as a key battleground. In a speech in Tucson last month, Vice President Kamala Harris tied the 1864 abortion ban — and similar restrictive measures in other states — to Trump, calling him "the architect of this health care crisis."
