In a win for President Trump, a panel of judges on the Fourth Circuit Court of Appeals has vacated a lower court ruling ordering 20 federal agencies to reinstate tens of thousands of employees they had fired.

The decision further clears the way for the Trump administration to re-fire, for now, probationary employees. Those are typically federal workers in their first or second year on the job, or who have been recently promoted into new roles.

In a 2-to-1 decision, the appeals court said the Trump administration was likely to succeed in showing that the lower court lacked jurisdiction in the case, which was brought by 19 states and the District of Columbia. The court did not rule on whether the probationary firings were lawful. It’s expected to consider the merits of the case in coming weeks.

The ruling comes a day after the Supreme Court vacated a different lower court ruling that ordered six federal agencies to bring fired employees back to work.

In an unsigned decision, the Supreme Court said the nonprofits that brought that case likewise lacked standing. The justices also did not rule on whether the firings were lawful. The Ninth Circuit Court of Appeals will consider the merits of that case in coming weeks.

The two decisions represent a significant setback for the states, the unions and the civic organizations that had sued the government in an effort to block the summary firings of more than 24,000 federal workers.

After initial wins in the lower courts, fired probationary employees are largely back where they started before the lawsuits were filed — save for thousands of Department of Agriculture employees who have been reinstated through April 18 by order of the Merit Systems Protect Board, a federal agency that considers employees’ workplace claims.

It’s unclear how quickly agencies might move to re-fire probationary employees. The vast majority have been reinstated at least to paid-leave status — and many to full duty status. The government has decried the process as costly and time-consuming.

The rulings come as the Trump administration has been pursuing other ways of downsizing the federal workforce.

A growing number of agencies have reopened their deferred resignation offers — allowing employees to resign now but keep their pay and benefits through September. Some recently reinstated probationary employees have accepted those offers, though others may have still been considering the option when these decisions came down.

Agencies have also begun rolling out their reorganization plans, outlining where they are planning mass layoffs, as directed by the Trump administration. The civil service rules governing reductions in force generally disadvantage employees with shorter tenure in the government. Probationary employees may be among the first to go, though they too must be given proper notice. At some agencies, that’s already happening.

The Department of Health and Human Services noted in a status report provided in the states’ case that more than 300 of the 2400 probationary workers it had reinstated had been issued termination notices under the agency’s pending reorganization.
