The complaint shall set forth such facts as are within the knowledge of the complainant to show probable cause to believe that a violation of law or abuse of discretion has occurred or will occur.

(1) without first filing a complaint under sub. (1), nor prior to disposition of the complaint by the commission.

5.06(5) (5) Upon receipt of a complaint under sub. (1), or upon its own motion, the commission may order any election official to immediately transfer to its possession any original documents in the custody of the official which the commission finds to be necessary and relevant to permit review of compliance with the laws concerning nominations, qualifications of candidates, ward division and numbering, recall or ballot preparation or the proper administration of such laws.

5.06(6) (6) The commission may, after such investigation as it deems appropriate, summarily decide the matter before it and, by order, require any election official to conform his or her conduct to the law, restrain an official from taking any action inconsistent with the law or require an official to correct any action or decision inconsistent with the law. The commission shall immediately transmit a copy of the order to the official. An order issued under this subsection is effective immediately or at such later time as may be specified in the order.

5.06(7) (7) The commission may withdraw, modify or correct an order issued under sub. (6) within a timely period if it finds such action to be appropriate.

(6) may appeal the decision of the commission to circuit court for the county where the official conducts business or the complainant resides no later than 30 days after issuance of the order. Pendency of an appeal does not stay the effect of an order unless the court so orders.

5.06(9) (9) The court may not conduct a de novo proceeding with respect to any findings of fact or factual matters upon which the commission has made a determination, or could have made a determination if the parties had properly presented the disputed matters to the commission for its consideration.

(2) (b), with due consideration for the known trends of population increase or decrease within that part of the municipality in which the ward is located.

5.15(1)(a)2. 2. Once established, the boundaries of each ward shall remain unchanged until a further decennial federal census of population indicates that the population of a ward is then above or below the applicable population range, or until the ward boundaries are required to be changed to permit creation of supervisory or aldermanic districts of substantially equal population or to enhance the participation of members of a racial or language minority group in the political process and their ability to elect representatives of their choice, or until otherwise authorized or required under this section.

5.15(1)(a)3. 3. If the population of a ward has increased above the maximum of its population range or if the population of a ward must be decreased for a reason specified in subd. 2., the ward shall be divided into 2 or more wards in compliance with sub. (2) (b). If the population of a ward has decreased below the minimum of its population range or if the population of a ward must be increased for a reason specified in subd. 2., the ward shall, if possible, be combined with an adjoining ward, or the underpopulated ward and one adjoining ward shall be combined and together subdivided into 2 or more wards in compliance with sub. (2).

5.15(1)(b) (b) Except as authorized in sub. (2) (a), within 60 days after the receipt of a tentative supervisory district plan and written statement, if any, from the county board of each county in which a municipality is located, the governing body of the municipality shall adjust its wards according to the schedule shown in sub.

Enactment or adoption of a division ordinance or resolution requires the affirmative vote of a majority of the members of the governing body.
