But the justices allowed a vaccination requirement for health care workers at facilities that receive federal money.
The Supreme Court on Thursday blocked the Biden administration from enforcing a vaccine-or-testing mandate for large employers, dealing a blow to a key element of the White House’s plan to address the pandemic as cases resulting from the Omicron variant are on the rise.
But the court allowed a more modest mandate requiring health care workers at facilities receiving federal money to be vaccinated.
The vote in the employer mandate case was 6 to 3, with liberal justices in dissent. The vote in the health care case was 5 to 4, with Chief Justice John G. Roberts Jr. and Justice Brett M. Kavanaugh joining the liberal justices to form a majority.
The employer mandate would have required workers to be vaccinated against the coronavirus or to wear masks and be tested weekly, though employers were not required to pay for the testing. There were exceptions for workers with religious objections and those who do not come into close contact with other people at their jobs, like those who work from home or exclusively outdoors.
