The U.S. Supreme Court restored the Trump administration’s ability to fire all probationary period employees, the latest in a dizzying series of court rulings. The nation’s top court agreed with an earlier court ruling that those challenging the terminations did not have standing to sue.

In February, the administration fired thousands of employees in their probationary periods, regardless of performance. Many of these employees were ordered to be reinstated when courts found the process of the terminations unlawful.

While the Supreme Court found the plaintiffs did not have standing to bring the lawsuits, the respective cases will proceed with hearings on the merits of the claims. The circuit court will proceed on an expedited schedule, and the probationary employees are considered terminated at this time.

“Every day the injunction remains in place, the government is obligated to continue paying thousands of employees it had previously terminated, with no practical mechanism to recoup those funds if it prevails on appeal,” the administration said.
