After opening the proceedings for the taking of evidence, the official in charge of the taking of evidence, i.e. in substantive examination and opposition proceedings the chair of the division concerned or the member commissioned for the taking of evidence, will determine whether any party requests that any other person present but not summoned is heard. If any party makes such a request they must briefly state why and to what purpose the person concerned should give testimony. The department in question will then decide on whether or not to grant the request (for the admission of facts or evidence not filed in due time see E‑VI, 2).
