(1) The powers of a county as a body corporate can only be exercised by the board, or in pursuance of a resolution adopted or ordinance enacted by the board.(2) Ordinances may be enacted and resolutions may be adopted by a majority vote of a quorum or by such larger vote as may be required by law. Ordinances shall commence as follows: "The county board of supervisors of the county of .... does ordain as follows".(3) A majority of the supervisors who are entitled to a seat on the board shall constitute a quorum. All questions shall be determined by a majority of the supervisors who are present unless otherwise provided.1977 c. 447; 1995 a. 201. The county board's failure to use the prescribed language of sub. (2) did not invalidate an ordinance. Cross v. Soderbeck, 94 Wis. 2d 331, 288 N.W.2d 779 (1980). A supervisor who is required to abstain is not "present" for calculating the number of votes required for passage. Ballenger v. Door County, 131 Wis. 2d 422, 388 N.W.2d 624 (Ct. App. 1986).
