North Dakota’s Supreme Court ruled Thursday the state’s abortion ban should remain on hold while a lawsuit over its constitutionality is resolved. North Dakota’s anti-abortion “trigger law” was supposed to take effect once Roe v. Wade was overturned, but a lower court temporarily blocked it last summer, arguing abortion rights are protected by the state Constitution. The legislation makes it a felony to perform an abortion — with limited exceptions in cases of rape, incest or medical emergency.
