The US Supreme Court on Monday overturned two key parts of an abortion law passed by the state of Texas that opponents said was unconstitutional because it unduly restricted a woman's right to the procedure.
The 5-3 ruling was the court's first in nine years on abortion, which remains contentious in the United States more than 40 years after it was legalized.
The lawsuit challenged two parts of the Texas law. One requires doctors who work in abortion clinics to have the ability to admit patients to hospital; the other requires abortion clinics to have equipment and other facilities similar to those found in outpatient surgical centres.
The court ruled that both the admitting privileges and surgical centre requirements place a substantial obstacle in the path of women seeking an abortion and therefore constitute an undue burden on abortion access, which violates the Constitution.
