I just read an interesting article in the NYT on the origins of the Humphrey's Executor case.
For Landmark Test of Executive Power, Echoes of a 1930s Supreme Court Battle
It goes back to 1933 when FDR tried to fire a member of the FTC, William Humphrey, who refused FDR's demand that he resign. Humphrey died before the case went to the SC but the executor for the estate pursued it. The Court correctly found for "Humphrey's executor"
unanimously. A precedent that has stood for over 90 years.
The request for him to step down “for purely political reasons” violated the law, Mr. Humphrey wrote. If a president could fire agency leaders, he said, “the independence, the purpose, character and value of all independent commissions will be destroyed.”
The president tried once more to cajole him.
“You will, I know, realize that I do not feel that your mind and my mind go along together on either the policies or the administering of the Federal Trade Commission, and, frankly, I think it is best for the people of this country that I should have a full confidence,” he wrote on Aug. 31.
Mr. Humphrey remained unmoved.
On Oct. 7, Mr. Roosevelt fired him.
FDR's rationale has a familiar ring to it. He wanted the people he wanted regardless of the statute protecting employees of independent agencies. Humphrey felt......
it was “unthinkable” to him that Congress would want leaders of independent agencies to be “in a position where their terms of office would be subject to the caprice of the man who happens, by the chance of politics, to occupy the White House.”
Humphrey, and the SC, were right. FDR was wrong. Some agencies were meant to be independent from executive overreach and Congress has the authority to protect them.
But for the Court's conservatives, who have a unitary view of all encompassing executive power, one the Founders rejected, law and precedent are mere annoyances to be steamrolled.
