The U.S. Court of Appeals for the Second Circuit on Wednesday refused to revive a challenge to President Donald Trump’s executive orders placing restrictions on public-sector unions’ ability to collectively bargain on behalf of their members.

A three-judge panel of the Manhattan-based appeals court upheld a lower court’s decision last year allowing the rules to go into effect and rejecting claims by one of the country’s largest unions that the president had overstepped his constitutional and statutory powers in rolling them out.
