Chun, a Seattle-based Biden appointee, is the third federal judge to block large portions of Trump’s March 25 Executive Order purporting to require states to alter their election processes. U.S. District Judge Colleen Kollar-Kotelly, a Washington, D.C.-based Obama appointee, in April blocked portions of the order forcing states to adopt new standards for voters’ proof of citizenship and a series of enforcement mechanisms. And U.S. District Judge Denise Casper, a Massachusetts-based Obama appointee, in June blocked provisions seeking to punish states that count ballots that arrive after Election Day.

The Trump administration has appealed Kollar-Kotelly’s and Casper’s rulings. Both appeals remain pending.

In response to the Friday ruling, a White House spokesperson said Trump “cares deeply about the integrity of our elections and his executive order takes lawful actions to ensure election security.”

“This is not the final say on the matter and the Administration expects ultimate victory on the issue,” spokesperson Abigail Jackson said.

All three judges found that Trump had exceeded his authority by purporting to mandate states to adjust their election procedures. The Constitution gives exclusive control of the “time, place and manner” to the states and Congress — an intentional decision to keep presidents at arm’s length from the procedures that govern their own elections. The federal government plays a role in funding state election systems, enforcing federal laws meant to protect election integrity and prosecuting election fraud. Those oversight functions don’t impinge on lawmakers’ power to set election procedures.

Trump has repeatedly made baseless claims of widespread fraud and cheating in blue states, rooted in part in his defeat in the 2020 election — and he has repeated those allegations in his efforts to pressure states to change their procedures.

Chun’s ruling was the first to contend with Trump’s demand that the Election Assistance Commission update voting system standards in specific ways — and then threaten funding for states that refuse to conform to those standards. It also bars a provision that could threaten funding for states that don’t require “documentary proof of citizenship” on federal voter registration forms.

“The Constitution assigns no authority to the President over federal election administration,” Chun wrote.
