Article 35 Representation
In any proceedings in an appeal, a party may act in person or be represented—
in the case of a person appealing against an immigration decision, by any person not prohibited by section 84;
in the case of the Secretary of State or any officer, by an authorised advocate or any officer of the Secretary of State; and
in the case of the United Kingdom Representative of the United Nations High Commissioner for Refugees in an asylum appeal, by a person appointed by him.
A person representing a party may do anything relating to the proceedings that the person whom he represents is by these Rules required or authorised to do.
Each party shall have a duty to maintain contact with his representative (if he has one) until the appeal is finally determined and notify the representative of any change of address.
Where a representative referred to in paragraph (1)(a) (“the first representative”) ceases to act, he and the party he was representing, shall forthwith notify the appellate authority and any other party of that fact and of the name and address of any new representative (if known).
Until the appellate authority is notified that the first representative has ceased to act by either the first representative or the party he was representing, any document served on the first representative shall be deemed to be properly served on the party he was representing.
Where a representative begins acting for a party to which these Rules apply, he shall forthwith notify the appellate authority of that fact.
