Art. 691
II. Unauthorised participation 1 The lending of shares for the purpose of exercising voting rights at a general meeting is forbidden if the intention in so doing is to circumvent a restriction on voting rights. 2 Every shareholder is entitled to object to the participation of unauthorised persons to the board of directors or in the minutes of the general meeting. 3 Where persons who are not authorised to participate in the general meeting participate in a decision on a resolution, any shareholder may challenge that resolution even if he has not raised an objection, unless the company can prove that their involvement exerted no influence on the decision made. |
