Illinois could soon begin to enforce a 1995 abortion law.
The measure requires doctors to notify the parents of a girls 17 and under 48 hours before she has an abortion done.
The only exception is if the girl can get permission from a judge.
On Thursday the Illinois Supreme Court says the case should not be reconsidered and must be enforced.
The only exception would be if the case was appealed to the U.S. Supreme Court.
Legal challenges to the law by the ACLU prevented the law from being enforced.
The civil rights organization stated that young women were able to make medical decisions.
But pro-life supporters said that if children were able to get abortions without their knowledge it would deny basic rights to parents.
