Article 35 Addition and substitution of parties
A person may make an application to be joined as a party to an application.
The Tribunal may make an order to join a person as a party to an application—
if a written application is made under paragraph (1), or
on the Tribunal’s own initiative if no written application has been made, but the person consents to be joined as a party to the application.
The Tribunal may make an order to substitute a party if—
the wrong person has been named as a party, or
the substitution has become necessary because of a change in circumstances since the application commenced.
If an order is made under paragraph (2) or (3) the Tribunal may make such consequential directions, or enquiries under rule 24, as the Tribunal considers appropriate.
Unless the Tribunal directs otherwise, a person appointed or substituted under this rule must be treated as a party for the purpose of any provision in these Rules requiring a document to be sent to or submitted by a party to the application.
