Final answer:
Military rule may take precedence over civilian authority during times of war or national security threats.
Step-by-step explanation:
A situation in which military rule would take precedence over civilian authority according to the Court's ruling is during times of war or national security threats. For example, during World War II, the Roosevelt administration interned Japanese Americans and tried them in military courts instead of the civilian justice system. The Supreme Court upheld this decision in Ex parte Quirin. Similarly, in response to the 9/11 attacks, the Bush and Obama administrations detained suspected terrorists and sought to avoid civilian trials. In these cases, national security concerns were prioritized over individual liberties.
