Marion County Superior Court Judge Heather Welch issued a preliminary injunction against the Republican-backed law, which prohibits abortions with limited exceptions for rape, incest, lethal fetal abnormalities or a serious health risk to the mother.
The plaintiffs have argued that the measure infringes on religious freedom protected by another state law.
The law had already been on hold, as another judge in September blocked Indiana from enforcing it while Planned Parenthood and other healthcare providers challenge it in court.
Court ruling on US abortion laws: Nick Harper
Indiana became the first state to pass a new law banning abortion after the US Supreme Court in June overturned its landmark 1973 Roe v. Wade ruling that had legalized the procedure nationwide. Other Republican-led states quickly began enforcing older bans.
Welch issued her injunction after a group called Hoosier Jews for Choice and five individual women challenged the abortion law under Indiana’s Religious Freedom Restoration Act in a case brought by the American Civil Liberties Union. The ACLU said the plaintiffs represented religions including Judaism and Islam as well as “independent spiritual belief systems.”
“The Court finds that S.E.A. 1 substantially burdens the religious exercise of the Plaintiffs,” Welch wrote, using the formal name of the law, in granting the plaintiffs’ motion for a preliminary injunction while the challenge to its legality proceeds.
