Lesson 13: Causation in Fact

Causation in fact is a fundamental element in establishing negligence. It determines whether the defendant's conduct actually caused the plaintiff's harm. This concept is often assessed using the "but-for" test.

"But-for" test: But for the defendant's actions, the plaintiff's harm would not have occurred.

Understanding the "But-for" Test

The "but-for" test helps to establish a direct link between the defendant's actions and the plaintiff's injury. If the harm would not have occurred "but for" the defendant's conduct, then causation in fact is established.

Example of "but-for" test:

  • Defendant runs a red light and hits Plaintiff's car.
  • Plaintiff suffers injuries from the accident.
  • But for the Defendant running the red light, Plaintiff would not have been injured.

Applying Causation in Fact

In legal practice, proving causation in fact requires a thorough examination of the circumstances surrounding the incident. The following diagram illustrates the process:

Challenges in Establishing Causation in Fact

There can be complexities in proving causation in fact, especially in cases involving multiple potential causes. Consider the following hypothetical scenario:

Hypothetical Scenario:

  • Two factories release pollutants into a river.
  • A local community suffers from health issues.
  • Both factories could be contributing to the harm.
