Indeed, even where an agent is authorised to exercise a function which is not a “delegable function” as defined in section 11, the authorisation will be valid. 89 Section 24 does not, of course, relieve trustees of any of their obligations under the Act.  They will still be liable for any loss incurred by the trust as a consequence of an ultra vires appointment.  In addition, if a person is authorised to exercise a function as an agent, that person may also be liable, as trustee de son tort, if the function in question is not properly delegable under section 11.  Both parties to the appointment have therefore an interest in ensuring that the appointment can properly be made.
