1 The Federal Commissioner shall inform the President of the Bundestag of any gifts received in connection with his or her office. 2 The President of the Bundestag shall decide how such gifts shall be used. 3 He or she may issue procedural rules and regulations.
1 The Federal Commissioner shall have the right to refuse to give testimony concerning persons who have confided in him or her in his or her capacity as Federal Commissioner and concerning the information confided. 2 This shall also apply to the staff of the Federal Commissioner, on the condition that the Federal Commissioner decides on the exercise of this right. 3 Within the scope of the Federal Commissioner’s right of refusal to give testimony, he or she shall not be required to submit or surrender files or other documents.
