君命有所不受. “There are commands of the ruler that are not to be accepted.” The line comes from the chapter on variations in tactics in Sunzi’s Art of War. Sunzi held that only the general who leads the troops knows the situation on the battlefield.
The saying is often quoted in a later form: 将在外，君命有所不受, “a general in the field need not accept every command of the ruler.”
It names an exception, and the exception depends on distance from the court.
