A principal, whether disclosed or otherwise is in position to plead all defences available to him, but in the case of fraud, where the Agent acts within the scope of his authority, actual or apparent, the act of fraud on the part of the agent binds the principal. The same goes for an act of undue influence, vis-a-vis the third party, brought to bear on the principal by the agent. The problem is one to be sorted out between the Principal and the Agent and not the third party.
