20 On the evidence, the fourth respondent was the agent of undisclosed principals, Mr and Mrs Fairclough, for the purposes of making the development application. Upon an agent ceasing to act in that capacity for any reason, in my view the undisclosed principal can step into the agent's shoes. For example, if a person named in a development application dies before it is determined, and if that person was an agent for an undisclosed principal, the undisclosed principal could require its name to be substituted for the applicant in the development application. It would be unnecessary to lodge a fresh development application. This may be significant where, for example, the statutory scheme has changed since the development application was lodged so as to make the proposed development impermissible on a new development application. The contrary seems to me to be an unlikely legislative intention. The applicant and the council did not submit to the contrary.
