Legal Definitions - actual cause

Actual cause is a crucial element in both civil and criminal cases. It is necessary to prove actual cause to establish liability in civil cases and a guilty verdict in criminal cases.

The but-for cause test is used to determine actual cause in both civil and criminal cases. This means that if the event would not have occurred but for the defendant's actions, then the defendant is considered the actual cause of the event.

For example, if a driver runs a red light and hits another car, causing injuries, the driver is considered the actual cause of the accident because the accident would not have occurred but for the driver running the red light.

Some jurisdictions also allow proving actual cause through alternative theories in criminal cases. However, once actual cause is established, proximate cause must also be established to return a liable/guilty verdict.

Overall, actual cause is an important factor in determining legal responsibility and accountability for events that cause harm or damage.
