Legal Definitions - had-not test

Definition: The had-not test, also known as the but-for test, is a legal doctrine used in tort and criminal law. It states that causation exists only when the result would not have occurred without the party's conduct.

For example, if a person is injured in a car accident and it can be proven that the accident would not have happened if the other driver had not been texting while driving, then the other driver's conduct is the cause of the injury under the had-not test.

The had-not test is important in determining liability and damages in legal cases. It helps to establish a clear link between the defendant's actions and the plaintiff's harm.
