Causa causans Law and Legal Definition

Causa causans literally means the primary cause or the originator of an action. It is the foundation of all the causes. It refers to the immediate cause that resulted in the damage. To get the damages the claimant must prove that the defendant’s breach of duty caused the harm. But the defendant need not prove the original cause of the harm. However while determining the question of harm the court will consider if the defendant has given explanation as to the original cause of the harm.
