At issue is a provision requiring health-care plans to cover no-cost preventive care, including cancer screenings, immunizations and contraception. A Christian-owned business has challenged it.

Lower courts ruled that a task force that determines which treatments must be covered at no cost had not been validly appointed.

The Supreme Court said Friday it will review the constitutionality of the Affordable Care Act’s no-cost coverage mandates for certain preventive care services, putting the landmark health care law in front of the justices again just as President-elect Donald Trump – who tried to repeal the law during his first presidency – returns to the White House.
