The Supreme Court's 5-4 ruling in the Lisa Cook case last week allowed the Federal Reserve governor to remain in office while her lawsuit challenging President Donald Trump's firing of her proceeds. The decision concluded that the Fed occupies a unique constitutional position among independent federal agencies.
In response, an extraordinary coalition of former top U.S. economic policymakers filed a 32-page amicus brief urging the court to preserve the Federal Reserve's independence and warning that expanding presidential control over the central bank could undermine confidence in American monetary policy.
What the Right Is Saying
Conservative legal scholars have argued that the Constitution grants presidents broad authority over executive branch officials, and that the special protections afforded to Fed governors lack explicit constitutional basis. Solicitor General D. John Sauer responded to the amicus filing in a statement, noting that the brief "did not address the legal issues at the heart of this case."
"Most of Cook's amici emphasize policy arguments, touting the perceived benefits of the Federal Reserve Board's independence in setting monetary policy," Sauer wrote. He added that "policy preferences are not the law, and these particular preferences lack any logical limit." Republican-appointed justices on the court largely sided with the administration in last week's ruling.
What the Left Is Saying
Democratic-aligned economists and progressive advocates have long argued that Fed independence from political pressure is essential for maintaining credibility in fighting inflation and managing monetary policy without political interference. The filing from former Fed chairs Alan Greenspan, Ben Bernanke, and Janet Yellen — including two who served under Democratic administrations — signals bipartisan concern about the implications of allowing presidents to remove sitting governors.
Former Treasury Secretary Lawrence Summers, a signatory who served under President Bill Clinton, joined colleagues in arguing that public confidence in central bank independence is already being tested by the current dispute. The brief states that "sectors that pay close attention to the Federal Reserve — including financial markets, the public, employers and lenders — are watching the current dispute over the President's removal of Governor Cook."
What the Numbers Show
The amicus brief was signed by every living former Fed chair: Alan Greenspan (served 1987-2006), Ben Bernanke (2006-2014), and Janet Yellen (2014-2018). The group also includes six former Treasury secretaries spanning roughly five decades of U.S. economic policymaking, as well as seven former White House economic advisors from administrations of both parties.
The Supreme Court ruled 5-4 in the case, with Justice Clarence Thomas writing separately to argue that the court's majority did not go far enough in addressing constitutional separation-of-powers questions. The court allowed Cook to remain in office while her lawsuit proceeds on narrower procedural grounds.
The Bottom Line
The Lisa Cook case has emerged as a major test of legal protections insulating the Federal Reserve from direct political control. While last week's ruling was narrowly tailored, it left unresolved broader questions about presidential removal authority over independent agencies. The amicus filing underscores how significant these stakes are for economic policymakers across the political spectrum. Cook's lawsuit is expected to continue in lower courts.
