The Iowa Supreme Court said Friday the state’s strict abortion law is legal, telling a lower court to dissolve a temporary block on the law and allowing Iowa to ban most abortions after about six weeks of pregnancy — before many women know they are pregnant.

The 4-3 ruling is a win for Republican lawmakers, and Iowa joins more than a dozen other states with restrictive abortion laws following the U.S. Supreme Court’s overturning of Roe v. Wade in 2022.

Currently, 14 states have near-total bans at all stages of pregnancy and three ban abortions at about six weeks.
