Vicarious liability is a legal concept where one person is held responsible for the actions of another. It is a strict liability principle, meaning even if the responsible party did not directly cause harm, they can still be held accountable. This principle is present in legal systems worldwide, including England, Australia, Canada, France, and Germany. Despite debates about its fairness, vicarious liability is considered necessary in modern society. Comparing how different countries handle this concept can help us understand its purpose and importance in a global economy.
