Preemptive Causation Law and Legal Definition

Preemptive causation is a legal involving two sufficient causes of something, but one occurs befor ethe other. For example, if John fires a shot a few seconds before Bill and Joe dies before Alice’s shot pierced his heart, then John’s shot would have preempted the causal role of Bill's shot. If Cynthia had missed, then Bill's shot would have killed Joe.
