The president issues a formal declaration
A national emergency is typically declared through a formal presidential proclamation or executive action invoking available statutory authority.

Section 3
Congress can oversee and terminate the emergency
Congress retains oversight tools, including legislation and statutory procedures for reviewing or terminating emergency declarations.
Section 4
Courts can review emergency actions
Emergency measures remain subject to judicial review, especially when they affect constitutional rights or exceed statutory authority.
