WEBER AND SARAVIA v. GERMANY DECISION 7 marked and were not used for purposes other than those listed in section 3(1). 24. Monitoring measures were supervised by two bodies, the Parliamentary Supervisory Board and the so-called G 10 Commission (see section 9 of the G 10 Act). At the relevant time, the Parliamentary Supervisory Board consisted of nine members of parliament, including representatives of the opposition. The Federal Minister authorising monitoring measures had to inform the board at least every six months about the implementation of the G 10 Act (section 9(1) of the G 10 Act). 25. The G 10 Commission consisted of a president who was qualified to hold judicial office and three additional members who were appointed by the Parliamentary Supervisory Board for the duration of one legislative term and who were independent in the exercise of their functions (see section 9(4) of the G 10 Act). The Federal Minister authorising surveillance measures had to inform the G 10 Commission monthly about planned monitoring measures and had to obtain its consent (section 9(2) of the G 10 Act; see paragraphs 55-58 below). Moreover, the Federal Minister had to inform the Commission whether or not persons concerned by such measures had been notified of them. If the Commission decided that notification was necessary, the Federal Minister had to arrange for it to be given without undue delay (section 9(3) of the G 10 Act). (b) Section 3(1) of the amended G 10 Act: Dangers for the avoidance of which monitoring of telecommunications could be ordered 26. Section 1(1), points 1 and 2, in conjunction with section 3(1), first and second sentence, authorised the monitoring of wireless telecommunications, that is, telecommunications which were not effected via fixed telephone lines, but, for example, via satellite connections (Überwachung nicht leitungsgebundener Fernmeldeverkehrsbeziehungen). 27. Section 3(1), first sentence, provided that restrictions on the secrecy of telecommunications could be ordered by the competent Federal Minister with the approval of the Parliamentary Supervisory Board, on an application by the Federal Intelligence Service, for international wireless telecommunications. Under the second sentence of that provision, such restrictions were permitted only in order to collect information about which knowledge was necessary for the timely identification and avoidance of certain dangers, namely: (1) an armed attack on the Federal Republic of Germany; (2) the commission of international terrorist attacks in the Federal Republic of Germany; (3) international arms trafficking within the meaning of the Control of Weapons of War Act and prohibited external trade in goods, dataprocessing programmes and technologies in cases of considerable importance;
