(Bloomberg) -- A US appeals court rejected the Justice Department's request to let federal officials fully move ahead with Donald Trump's overhaul of mail voting ahead of the November midterm elections, leaving in place a Boston judge's order that declared the president's policies unlawful. Most Read from BloombergA three-judge appellate panel said it would not pause a lower court ruling that barred federal agencies from immediately enforcing Trump's executive order in almost two dozen states and the District of Columbia where Democratic officials sued. Several other legal challenges are pending against the president's directives, including a lawsuit brought by the Democratic National Committee and party leaders in Congress. The Justice Department signaled in earlier court filings that it would consider taking the fight to the US Supreme Court. While the Boston judge's injunction doesn't apply nationwide, it's considered a significant impediment to the administration's ability to carry out Trump's executive order for the November vote.
