Planned Parenthood has asked a federal judge to grant a preliminary injunction preventing a new South Dakota abortion law from taking effect while it's being challenged in court.

Chief Judge Karen Schreier didn't specify Monday when she would rule on the matter.

The law set to take effect Friday requires women seeking abortions to face a three-day waiting period and undergo counseling at pregnancy help centers that discourage abortion.

The lawsuit says the law violates a woman's constitutional right to abortion established under the 1973 Roe v. Wade ruling.

Supporters of the measure say the Planned Parenthood clinic in Sioux Falls gives women little information or counseling before they undergo abortions. They say the bill would help make sure women are not being coerced into abortions by boyfriends or relatives.
