The case grew out of a conservative religious challenge to the approval of HIV prevention treatments that insurers are required to provide at no cost to patients.

The Supreme Court on Friday rejected a challenge to an Affordable Care Act provision that set up a panel to recommend preventive care services that insurers must provide at no cost to patients.

The court, split 6-3, ruled in favor of the Trump administration, which was defending the law, saying the task force members are lawfully appointed under the Constitution's appointments clause.

The task force members are under the supervision of the health and human services secretary, a position held by Robert F. Kennedy Jr., which addresses any concerns that it is not accountable to the executive branch, the court found in an opinion written by Justice Brett Kavanaugh.

Three conservative justices dissented.
