Emergency powers grant presidents expanded authority during crises, allowing them to issue executive orders and declare national emergencies. The National Emergencies Act and War Powers Resolution provide frameworks to balance executive power with congressional oversight and limit prolonged military engagements.
Constitutional considerations during emergencies involve balancing individual rights with public safety. Federalism principles distribute emergency response responsibilities between state and federal governments, while courts evaluate the constitutionality of emergency measures based on their necessity, scope, and duration.
