The Supreme Court on Tuesday permitted an Indiana abortion law governing the disposal of fetal remains. But it declined to revive the state's ban on so-called discriminatory abortions based on the fetus' expected race or disability status. Both laws were signed by Vice President Mike Pence when he was governor of the state. The court's action represents an incremental move on an explosive social issue that President Donald Trump has signaled he will make an election year talking point. The announcement comes as conservative states across the country are passing laws in the hopes of prompting the top court to review its abortion precedents included the landmark 1973 decision in Roe v. Wade. But the court did not appear to be in a hurry to review those precedents on Tuesday and avoided some of the most contentious legal areas related to reproductive rights.

The court noted that its decision to overturn a lower court's ruling and permit the fetal remains law, which among other provisions bars the incineration of fetal remains alongside surgical byproducts, was not based on the "undue burden" test that has formed the crux of many challenges to restrictive abortion laws. The Supreme Court has said that state abortion regulations are permissible as long as they do not unduly burden a woman's constitutional right to terminate her pregnancy. With regard to the discriminatory abortion ban, the justices wrote that they did not take a position on the constitutionality of the regulation. The 7th U.S. Circuit Court of Appeals struck down the law. The top court wrote in the unsigned order letting the appeals court ruling stand that its decision was based on its "ordinary practice" of waiting to take a case until more than one appeals court decides on a legal question. Only the 7th Circuit has decided a case involving such a law, the court said. The announcement was made in an order released on the court's website. The notice said Justices Ruth Bader Ginsburg and Sonia Sotomayor would have let the lower court ruling that blocked the fetal remains law stand. In a statement, a Pence spokeswoman commended the Supreme Court for "upholding a portion of Indiana law that safeguards the sanctity of human life by requiring that remains of aborted babies be treated with respect and dignity." "We remain hopeful that at a later date the Supreme Court will review one of numerous state laws across the U.S. that bar abortion based on sex, race, or disability," Alyssa Farah, the spokeswoman, said.
