Postmaster General Louis DeJoy may have to testify under oath about his agency’s failure to follow court orders to avoid delivery disruptions for mail-in ballots during the election.

A federal judge ordered the U.S. Postal Service to make every effort to deliver mail-in ballots in three crucial swing states by Election Day due to uncertainty over whether votes that arrive after that will be counted.

A federal judge ordered Postmaster General Louis DeJoy to immediately begin authorizing more late delivery trips after an earlier injunction against the U.S. Postal Service’s disruptive operational changes failed to improve performance before the Nov. 3 election.

Delivery delays during an election can’t be unlawful, because the Constitution doesn’t guarantee states any particular level of service when it comes to mail-in ballots, the U.S. Postal Service told a federal judge.

A federal judge ordered the U.S. Postal Service to restore high-speed mail-sorting machines at any facilities that are unable to process first-class election mail quickly enough — a major concern for states as the postal agency continues to struggle with service performance.

States that claim changes by the U.S. Postal Service will threaten mail-in voting failed again to get an independent monitor appointed to observe the agency’s compliance with a court order.

The U.S. Postal Service still isn’t processing election mail on time, even after being ordered by judges to halt disruptive changes like banning worker overtime and late delivery trips, Pennsylvania’s attorney general said.

The delivery of election mail could be disrupted by operational changes arising from competing national court orders, the U.S. Postal Service warned.

A federal judge in Philadelphia joined others Sept. 28 in ordering a halt to recent Postal Service cuts that critics say are causing mail delays and threatening the integrity of the presidential election.

Postmaster General Louis DeJoy told a judge that a court order directing the U.S. Postal Service to reinstate overtime to ensure speedy delivery of mail-in ballots for the Nov. 3 election could be abused by workers.
