"[The president] may require the Opinion, in writing, of the principal Officer in each of the executive Departments"
Could you please explain why that clause is there if the president can already threaten to fire anyone who doesn't comply with their orders?
Hamilton thought it was superfluous. Federalist 74 says:
> “The President may require the opinion in writing of the principal officer in each of the executive departments upon any subject relating to the duties of their respective offices.” This I consider as a mere redundancy in the plan; as the right for which it provides would result of itself from the office.
Note that this provision must be redundant even without a unitary executive. Because otherwise, the implication is the only thing the President can do with principal officers is to ask them for an opinion.
Some modern scholars think the provision, though functionally redundant, is there to address a dispute that arose during the debates about executive councils: https://www.yalejreg.com/nc/reconciling-the-unitary-executiv... (“Unsurprisingly, the issue of an executive council arose at the Philadelphia Convention. Several proposals to create a council of state or a privy council were offered. Some of the proposed councils would have provided advice to the President but would not have required that he follow it, whereas others might have required that he secure the consent of the council. But each of the proposals was rejected. Instead, the Convention took language from part of one of the executive council proposals – ‘he may require the written opinions of any one or more members” of the council – as a model for the Opinions Clause.’”).
So the clause is there not to describe what the principal officers must do, but what the President need not do. The President may but does not need to consult his principal officers before taking action.
