Whenthe intermediary acts without a mandate, orbeyond his mandate, his acts
are not binding either to the principal or the third party referred to in article 169above.
However,when the behavior of the principal leads the third party to believe, reasonably and in
good faith, that the intermediary has the power to act on behalf of the principal, the latter shall
not rely on the lack of the intermediate power with respect of the third party.
