The record should state the place and date of the hearing and the names of those participating and involved.
(4) The record is to be read out to the witnesses for approval, or submitted to them for their own review. The approval given is to be noted and signed by the persons concerned. Where the signature is omitted, the reason for this is to be stated.
(5) Subsections (3) and (4) apply correspondingly to the examination of experts.
(6) The Federal Network Agency may request the local court to administer an oath to witnesses, where it considers the oath necessary to obtain a truthful statement. The court decides on administering the oath.
