U.S. District Judge Richard Leon ruled to keep the status quo, saying that an order allowing employees considered essential to skip work would be "chaotic" in a best-case scenario and "catastrophic" at worst.
Lawyers representing the National Air Traffic Controllers Association had sued the Trump administration to get their controllers, thousands of whom continue to work and just missed a paycheck, be paid while working during the shutdown in order for them to remain "laser-focused" on their job guiding more than 40,000 flights through the nation's airspace every day.
Lawyers for the labor unions, including National Treasury Employees Union, argued withholding pay while forcing labor is unconstitutional and violated U.S. labor laws.
Leon said only Congress can appropriate the funds to pay federal workers and would not force the Treasury Department to allocate funds to the furloughed employees.
