Appeals court blocks Trump from firing federal board members, tees up Supreme Court fight

The majority cited Supreme Court precedent in Humphrey's Executor and Wiener v. United States as the backing for their decision, noting that the Supreme Court had never overturned or reversed the decades-old precedent regarding removal restrictions for government officials of "multimember adjudicatory boards" - including the NLRB and MSPB.

"The Supreme Court has repeatedly told the courts of appeals to follow extant Supreme Court precedent unless and until that Court itself changes it or overturns it," judges noted in their opinion. 

Also on Monday, the appeals court rejected the Trump administration's request for an administrative stay, which would have allowed their removals to remain in place while the challenge continued to play out in federal court. 

The panel found that the administration had not demonstrated a strong likelihood of success on the merits of its appeals, nor did it show irreparable injury if they did not grant the stay - the legal requirements needed to satisfy an emergency court intervention. 

The en banc ruling reverses a decision reached just 10 days earlier by a three-judge panel for the same appeals court. That panel ruled 2-1 in favor of the Trump administration and allowed the firings to proceed, prompting plaintiffs to file a request for the appeals court to hear the case again en banc, or with all appellate court judges present.

The appellate court's decision to hear the case again, even after a three-judge appellate panel from the same court ruled on the issue late last month, is likely to be met with intense scrutiny by Trump and his allies. 

It also all but ensures that the Trump administration will move quickly to appeal the matter to the Supreme Court for emergency review.

Since taking office, Trump has signed more than 300 executive orders and actions, including sweeping personnel moves, the restructuring of federal agencies, and the creation of the so-called Department of Government Efficiency, or DOGE - a temporary agency that has drawn scrutiny for its broad oversight powers and access to sensitive government data.

The Trump administration has appealed its early losses to the Supreme Court - a strategy it appears poised to continue in the NLRB and MSPB terminations.
