The Supreme Court won't hear an appeal challenging the constitutionality of a Colorado law that prohibits people from obstructing entry to abortion clinics.

The justices on Monday left in place a lower court ruling that said the law does not restrict free speech or otherwise violate the rights of abortion protesters.

Protester Jo Ann Scott was convicted of violating the law after a jury found that she made physical contact with a woman trying to enter a Planned Parenthood clinic in Denver. An appeals court affirmed.

Scott argued that the law contains vague and overly broad terms that give police too much discretion to enforce it.
