In pulling the rule, the Labor Department recognized what most employers and industry experts said after the court’s ruling — that the emergency temporary standard could not be revived after the Supreme Court blocked it earlier this month.

“It’s their admitting what everyone had been saying, which is that the rule is dead,” said Brett Coburn, a lawyer at Alston & Bird.

The Supreme Court’s decision, which was 6 to 3, with the liberal justices in dissent, said the Labor Department’s Occupational Safety and Health Administration, or OSHA, did not have the authority to require workers to be vaccinated for coronavirus or tested weekly, describing the agency’s approach as “a blunt instrument.” The mandate would have applied to some 80 million people if it had not been struck down.
