INDIANAPOLIS (AP) – A federal judge says she decided to block an Indiana law prohibiting abortions sought because of a fetus’ genetic abnormalities because the state doesn’t have the authority to limit a woman’s reasons for ending a pregnancy.

U.S. District Court Judge Tanya Walton Pratt granted a preliminary injunction Thursday sought by Planned Parenthood of Indiana and Kentucky. The decision came a day before the law was to take effect.

Pratt said the Indiana law would go against U.S. Supreme Court rulings that states may not prohibit a woman from seeking an abortion before fetal viability.

An attorney for Indiana argued before Pratt earlier this month that the state has an interest in “preventing discrimination” against fetuses with genetic abnormalities, such as Down syndrome.
