The judges opposed the law, which provides for restrictions on doctors who have abortions.
The U.S. Supreme Court on Monday ruled against Louisiana law restricting physicians providing abortion services.
The law requires abortion doctors to obtain permission to hospitalize patients in a hospital located within a 48 km radius of the clinic.
Opponents of abortion hoped that the Supreme Court would uphold the restrictions imposed in Louisiana and several other conservative states.
This is the second time in four years that the Supreme Court has ruled against such restrictions.
In 2016, the court spoke out against Texas law, which also required doctors to have permission to hospitalize patients in neighboring hospitals, and clinics to have expensive hospital-level equipment. The judges considered that these restrictions placed an “excessive burden” on a woman’s ability to have an abortion.
