Section 193.515 - Special members' meetings(1) CALLING A MEETING. A special members' meeting may be called by any of the following means: (b) By petition of the members under this paragraph. Except as otherwise provided in this paragraph, the chairperson of the board shall call a special members' meeting if a written petition requesting the meeting is signed by at least 20 percent of the patron members and is submitted to the chairperson. Unless the articles or bylaws provide otherwise and except as otherwise provided in this paragraph, the chairperson of the board shall call a special members' meeting if a written petition requesting the meeting is signed by at least 20 percent of the nonpatron members, 20 percent of all members, or members representing 20 percent of all membership interests and is submitted to the chairperson. A special members' meeting held under this paragraph shall be held within 30 days after submission of the petition to the chairperson. This paragraph does not authorize any meeting that is unrelated to a proper cooperative purpose.(2) NOTICE. Except as otherwise provided in this subsection, sub. (3), and s. 193.553, the cooperative shall mail a notice of any special members' meeting to each member at the member's last known address. In lieu of mailing, the cooperative may provide notice of the meeting by any means approved by the board and agreed to by the members. Any notice provided to an entity under this subsection shall be addressed or directed to an officer of the entity. Any notice provided under this subsection shall state the time, place, and purpose of the meeting. Any notice provided under this subsection shall be given at least 10 days before the date of the meeting.(3) WAIVER AND OBJECTION. A member may waive notice of a special members' meeting. A waiver is effective whether given before, at, or after the meeting, and whether given in writing, orally, or by attendance. Attendance by a member at a special members' meeting is a waiver of notice of that meeting, except where the member objects at the beginning of the meeting to the transaction of business because the meeting is not lawfully called or convened and does not participate in the meeting after the objection, or objects before a vote on an item of business at the meeting because the item may not lawfully be considered at the meeting and does not participate in the consideration of the item at the meeting.
