A federal judge in Seattle has ruled that Washington's state Department of Labor and Industries did not violate the tech giant's right of due process when it required Amazon to implement safety upgrades while the company appeals the state's citations for unsafe working conditions at its warehouses.

After state regulators cited Amazon in October for allegedly failing to create a safe work environment at its warehouses, Amazon filed suit in federal court claiming its constitutional right to due process was violated because it was expected to implement safety upgrades while it appeals the citation.

In a ruling on Tuesday, US District Judge John Coughenour found that the speed of the upgrade is warranted because Amazon's workers are toiling under conditions the state has found to be unsafe—and because the company failed to notify its workers that it was appealing the state's citations—the Seattle Times reported.
