The Department of Justice requested Monday that the Supreme Court temporarily block enforcement of the Texas law outlawing abortion procedures after six weeks of pregnancy.

The request marks the second challenge by the DOJ to reach the court on an emergency appeal that seeks to place a hold on the ban while litigation contesting its constitutionality plays out in lower courts. In early September, the Supreme Court turned away the first appeal by a 5-4 vote, allowing the law to take effect.
