7.—(1) Where a party to an action dies or becomes bankrupt but the cause of action survives, the action shall not abate by reason of the death or bankruptcy.
(2) Where at any stage of the proceedings in any cause or matter the interest or liability of any party is assigned or transmitted to or devolves upon some other person, the Court may, if it thinks it necessary in order to ensure that all matters in dispute in the cause or matter may be effectually and completely determined and adjudicated upon, order that other person to be made a party to the cause or matter and the proceedings to be carried on as if he had been substituted for the first mentioned party.
An application for an order under this paragraph may be made ex parte.
(3) An order may be made under this rule for a person to be made a party to a cause or matter notwithstanding that he is already a party to it on the other side of the record, or on the same side but in a different capacity; but—
(a)if he is already a party on the other side, the order shall be treated as containing a direction that he shall cease to be a party on that other side, and
(b)if he is already a party on the same side but in another capacity, the order may contain a direction that he shall cease to be a party in that other capacity.
(4) The person on whose application an order is made under this rule must procure the order to be noted in the cause book, and after the order has been so noted that person must, unless the Court otherwise directs, serve the order on every other person who is a party to the cause or matter or who becomes or ceases to be a party by virtue of the order and serve with the order on any person who becomes a defendant a copy of the writ or originating summons by which the cause or matter was begun.
(5) Any application to the Court by a person served with an order made ex parte under this rule for the discharge or variation of the order must be made within 14 days after the service of the order on that person.
