The court put its ruling on hold for the moment, allowing two weeks for arguments about the ban’s constitutionality.
But if the law goes into effect, it will have far-reaching consequences for both abortion access and national politics.
Until now, abortion has been legal in Arizona through 15 weeks of pregnancy.
But the 1864 law, which was enacted many decades before Arizona became a state, outlaws abortion from the moment of conception, except when the procedure is necessary to save the life of the mother.
Clinics in Arizona could soon close, forcing women seeking abortions to travel to California, New Mexico or Colorado to end their pregnancies.
