A federal judge blocked Idaho authorities Tuesday from prosecuting Planned Parenthood for helping women and girls travel out of state to kill their unborn babies in elective abortions.

Immediately afterward, pro-life leaders warned that U.S. District Judge Lynn Winmill’s ruling will put women’s and children’s lives at risk.

The case, filed by Planned Parenthood and the American Civil Liberties Union, claims the Idaho abortion ban violates their free speech rights based on a letter from Attorney General Raúl Labrador in March, The Daily News reports.
