Abortion clinics in Ohio are pushing for a court to strike down abortion restrictions now that voters have enshrined abortion rights into the state Constitution, arguing that even the state’s Republican attorney general says the amendment invalidates the ban.

The push comes on the heels of an amendment that Ohio voters approved last month that ensures access to abortion and other reproductive health care. It took effect last week.

A law signed by Republican Gov. Mike DeWine in April 2019 prohibited most abortions after the first detectable “fetal heartbeat.” Cardiac activity can be detected as early as six weeks into pregnancy, before many women know they are pregnant.

The law had been blocked through a federal legal challenge, briefly went into effect when the landmark 1973 Roe v. Wade decision was overturned, and then was again put on hold in county court.
