The latter are executive functions.” (internal quotation marks omitted)); Mistretta v. United States, 488 U.S. at 391 n. 17, 109 S.Ct. 647 (<HOLDING>). This I expect is why the Supreme Court has

A: holding that unless that power is restricted by the principal an agent under a california statutory healthcare power of attorney has the power to execute applicable admission forms including arbitration agreements
B: holding that the power to terminate a contract atwill subsumes the power to modify its terms
