The Supreme Court on Thursday declined to take up a dispute over a Montana law that would have required notarized parental consent for a minor to receive an abortion. State lawmakers have argued that parents have a constitutional right to make decisions concerning the care, custody and control of their children.

The move disappointed abortion opponents. But two of the court's conservative justices - Alito and Thomas - said it may take up the issue in the future.

The U.S. Supreme Court declined on Thursday to hear a bid by Montana to revive a law that requires parental consent for minors to obtain an abortion, a measure challenged by reproductive health and abortion provider Planned Parenthood as a violation of the Republican-led state's constitution.
