As to the torts of an agent, the rule is the contrary to the rule as to his acts in contracting. The agent is bound to third persons, who are injured by his wrongful acts, even though they are done by him solely as agent, and this is true whether they are, or are not done under authority from the principal. Every wrong doer must answer for his acts. The fact, that the principal is also liable, would not be a defense. An agent must also answert o a third person for a false warranty of authority to act.
