The Supreme Court on Thursday temporarily blocked a restrictive Louisiana abortion law from going into effect Friday, a measure providers say would have drastically reduced the number of doctors authorized to perform the procedure.

Why it matters: This case presented a swift test to the Supreme Court’s newly strengthened conservative majority, as anti-abortion forces hope it will overturn long-standing precedents on cases concerning abortion rights. Chief Justice John Roberts joined the more liberal justices in granting the stay, with the court voting 5-4.

Details: Last week, the high court temporarily blocked the state’s abortion law, passed in 2014, from going into effect next Monday. Justice Samuel Alito said that the Court needed more time to review the various filings before ruling on the emergency application filed by an abortion provider.
