Special meetings may be called by the Mayor or by any two members of the City Council upon at least 24 hours written notice to each member of the City Council. This notice shall be mailed to and either delivered personally to each member or shall be left at the member’s usual place of residence with some responsible person. Pursuant to M.S. § 16D.04, as it may be amended from time to time, written notice of any special meeting shall be posted giving the date, time, place and purpose of the meeting at least three days before the meeting. Written notice shall be mailed at least three days before the meeting to anyone who has filed a written request for notice of special meetings. In calculating the three days, if the last day falls on a Saturday, Sunday or legal holiday, the next regular business day shall be counted as the third day. The only business which may be discussed and acted upon at the special meeting are those items contained in the notice of the special meeting.
