70.4. No member of the Council, the executive committee or a select or special committee may, as part of his duties, perform any act involving expenses chargeable to the Community except with the prior authorization of the Council to perform the act and incur, in consequence thereof, expenses not exceeding the amount fixed by the Council.
However, the chairman of the Community is not required to obtain prior authorization when acting in his capacity as representative of the Community. Such exemption also applies to any other member of the Council designated by the chairman to replace him as representative of the Community on any occasion on which neither vice-chairman is able to replace him in accordance with section 31.6.
