v t e

In commercial law, a principal is a person, legal or natural, who authorizes an agent to act to create one or more legal relationships with a third party. This branch of law is called agency and relies on the common law proposition qui facit per alium, facit per se (from Latin: "he who acts through another, acts personally").

It is a parallel concept to vicarious liability (in which one person is held liable for the acts or omissions of another) in criminal law or torts.
