A federal appeals court on Wednesday temporarily prohibited Arizona from enforcing its new ban on most abortions starting at 20 weeks of pregnancy. A three-judge panel of the 9th U.S. Circuit Court of Appeals issued its order two days after a trial judge ruled that the ban could take effect Thursday as scheduled.

Abortion-rights groups appealed U.S. District Judge James Teilborg’s ruling that the ban is constitutional, partly because of concerns about the health of women and possible pain for fetuses.

The case centers on whether the ban violates U.S. Supreme Court rulings that states cannot prohibit abortion before a fetus is able to survive outside the womb. That’s generally considered to be about 24 weeks. Normal pregnancies run about 40 weeks.

Arizona currently bans abortions at viability.
