states and courts have no standing
Only the congress can overrule an emergency declaration and that is by joint resolution which the president can veto.
The USSC has ruled before during Truman and FDR administrations. On eon internment ofJapanese. But I don’t know if a president has said, the court has no
standing. The check and balance is the congress. You can’t respond emergencies if 1 judge or panel can overrule you. That’s why the CIC has the power.
SCOTUS upheld FDR's emergency orders during WWII (Japanese internment) but overturned Truman's during the Korean War (taking temporary control of the steel mills).
