Which ideas to limit the president's firing power happened or went to court?

"Dellinger v. Bessent (D.D.C.), 1:25-cv-00385, [ 368 ] appealed to the D.C. Cir., 25-5025 [ 369 ] / 25-5028 [ 370 ] / 25-5052, [ 371 ] appealed to the Supreme Court, Bessent v. Dellinger , 24A790 [ 372 ] (case closed after petitioner withdrew it)"

"In Seila Law LLC v. Consumer Financial Protection Bureau (2020), the Roberts Court held 5–4 that the Executive Vesting Clause gives "the entire 'executive Power' ... to the President alone.""

"Harris v. Bessent (D.D.C.), 1:25-cv-00412, [ 375 ] appealed to the D.C. Cir., 25-5055 [ 376 ] and 25-5037, [ 377 ] appealed to the Supreme Court, Bessent v. Harris (consolidated with Trump v. Wilcox )"

"Aviel v. Gor (D.D.C.), 1:25-cv-00778, [ 364 ] appealed to the D.C. Cir., 25-5105 [ 365 ]"

"The Court reaffirmed that precedents found in Humphrey's Executor and Morrison were the only exceptions to this removal power."

"He undertook mass firings of employees , inspectors general , and independent agency and oversight board members who might obstruct him."

"Legal analysts said these actions set up Supreme Court tests on agencies Congress insulated from presidential control."

"In Trump v. Slaughter , the U.S. Supreme Court overruled Humphrey's Executor v. United States (1935), holding that Congress generally cannot shield leaders of executive agencies from presidential removal through "for-cause" protections."

"In Trump v. Slaughte r, a 6–3 majority overruled Humphrey’s Executor v. United States"

"On Monday morning, the Supreme Court overruled Humphrey’s Executor , the 1935 decision that for more than 90 years let Congress shield the heads of independent agencies from being fired at a president’s whim. The vote was 6–3."

"Chief Justice John Roberts, writing for the Court, held that for-cause removal protections for the heads of agencies exercising executive power violate the Constitution’s separation of powers."

"By 5–4, with the chief justice and Justice Brett Kavanaugh joining the three liberal justices who had just dissented in the FTC case, the court refused to let the president remove Cook from the Federal Reserve."

"The district court, applying Humphrey’s Executor , ordered her restoration. The Supreme Court stayed that order, granted certiorari before judgment, and reversed."

"Within months, the administration made that argument, in Wilcox, then in Trump v. Slaughter , the Federal Trade Commission case the court has now decided."

"today’s companion case, Trump v. Cook , appears to recognize an exception — “a special arrangement sanctioned by history” — for central banking that serves to insulate the Federal Reserve Board of Governors from presidential removal."

"In a companion case handed down the same hour, the court spared the Federal Reserve, the one exception it had long flagged, and let board member Lisa Cook keep her seat by a 5–4 vote."
