LITTLE ROCK, Ark. (AP) - A federal judge is hearing arguments on a request to block an Arkansas law that critics say effectively bans abortion pills, a little over a week after the U.S. Supreme Court allowed the state to enforce the restriction.

The law said doctors who provide abortion pills must hold a contract with a physician with admitting privileges at a hospital who agrees to treat any complications.

U.S. District Judge Kristine Baker plans to hear arguments Friday morning on Planned Parenthood's request to block the law.

Justices last week rejected a Planned Parenthood appeal to reinstate Baker's earlier order blocking the law. Planned Parenthood said the law effectively ends medication abortions in Arkansas.
