Legal Principle: Volenti non fit injuria, a well-established legal principle, means that a person has no legal remedy for the injury caused by an act which he has consented. Factual Situation: An old man was walking in a narrow one-way lane in the opposite direction. It was night time and there was no street lighting. A car moving in right direction but without headlights knocked him down since the driver could not see him. He filed a suit against the driver.
