A danger or risk of harm that is about to occur without delay. The condition requires that the threatened injury be immediate rather than remote or contingent, so that defensive measures or special governmental powers become available only when action cannot safely await further events.

State Responds to Border Incursion
State officials learn that armed forces from a neighboring country have crossed the border and are advancing toward populated areas. Because the invasion creates an imminent threat that will not admit of delay, the state mobilizes its militia and engages the intruders without first obtaining congressional consent.
Employer Ignores Worker Peril
A delivery driver becomes trapped inside a collapsed warehouse while making a scheduled stop. The employer learns of the entrapment yet fails to send rescue equipment, allowing the driver to suffer serious injuries that could have been prevented by prompt action.

Subway Rider Shoots Assailants

A city enacts a noise ordinance that limits demonstrations near school buildings during class hours. Challengers contend the law is vague because it fails to define when student activity creates an imminent threat of disruption.
Common questions
Frequently Asked
5
How does an imminent threat differ from a future or conditional threat in self-defense analysis?+
An imminent threat exists only when harm is about to occur without delay, so that defensive force becomes necessary at that moment. A conditional or future threat leaves time for other responses and therefore does not justify immediate force.
Supporting sources
Does the passage of several hours after an assault eliminate an imminent-threat claim in provocation or self-defense cases?+
Yes. When the defendant has time to rest or engage in ordinary activities, the law treats the initial danger as no longer imminent and requires proof that the defendant actually cooled off before acting.
Supporting sources
Can a state invoke the imminent-danger exception in Article I, Section 10 without an actual invasion?+
The exception applies when danger is so pressing that delay is impossible, even if invasion has not yet occurred, provided the threat is immediate rather than speculative.
Supporting sources
What must a master know to face liability under the imminent-danger rule for an employee?+
The master or a management-level person must know that the servant faces imminent danger of serious harm while acting within the scope of employment, triggering a duty to exercise reasonable care to avert the harm.
Supporting sources
Does a vague ordinance create an imminent threat of enforcement for standing purposes?+
Standing may exist when the ordinance imposes a credible threat of repeated prosecution that chills protected conduct, but the threat must be immediate rather than merely possible in the future.
