If for any reason any of the court reporters or office secretaries shall be unable to perform his or her duties, the Chancellor may appoint a suitable and competent substitute to serve as a temporary court reporter or office secretary for such time and for such compensation as he or she shall determine. Substitute court reporters shall take the same oath of office as is required of a court reporter, and their acts shall have the same force and effect as if done by an official court reporter. Such oath shall not be recorded, but shall be filed with the Register.
