28. Death or incapacity of registered attorney

28. If any such registered attorney as in the last preceding section is mentioned shall die, or be removed or suspended, or otherwise become incapable to act as aforesaid, at any time before judgment, no further proceeding shall be taken in the action against the party for whom he appeared until thirty days after notice to appoint another registered attorney has been given to that party either personally or in such other manner as the court directs.

Where a proxy is granted to two attorneys and one of the attorneys died before the trial does not invalidate the proxy and surviving attorney can continue to appear.
