The sanction of force stands behind the medley of personal orders and regulations of Martial Law. The sanction of the people's consent stands behind the hierarchy of laws. In one situation, the population is regimented into acquiescence. In the other, the population voluntarily establishes a contract with Parliament. For this reason, one is called a regime and the other, a government. Martial law rests on the sanction of force and not on the sanction of law.
