Where the conduct of the principal causes the third party reasonably and in good faith to believe that the agent has authority to act on behalf of the principal and the agent is acting within the scope of that authority, the principal may not invoke against the third party the lack of authority of the agent ("agency by estoppel", "Anscheinsvollmacht").
