The Oklahoma House of Representatives has passed a bill that will make it more difficult for a minor to get an abortion in the state without parental consent.
Oklahoma law had already required minors to wait 48 hours for an abortion unless they had a judge's consent, or in the event of a medical emergency.
The new guidelines will specify more precisely how parental consent forms would be worded, and how a judge should decide whether a minor is capable of making an informed decision on abortion.
The Senate had put some amendments into the measure, which the House passed Tuesday by a vote of 82-5 without debate.
The bill now goes to Gov. Mary Fallin for final approval.
