The narrower purpose of this amended complaint is to challenge the Government’s purported revocation of Mr. Maehr’s passport under the FAST Act, 26 U.S.C. § 7345. This recently-enacted statute directs the IRS to provide the State Department with a list of citizens who owe tax debts above $50,000. The State Department then revokes the passport of, or does not issue a passport to, any person on that list.
