President Donald Trump has repeatedly attacked Comey and James, declaring in one social media post, "They're all guilty as hell", and later adding "JUSTICE MUST BE SERVED, NOW!!!"
In her decision on Monday, Judge Currie wrote that Halligan, a former White House aide who had never prosecuted a case before, was not authorised to present the charges to the grand jury.
"All actions flowing from Ms Halligan's defective appointment, including securing and signing Mr Comey's indictment, were unlawful exercises of executive power and are hereby set aside," Currie ruled.
