(1) PREREQUISITES. One or more members of a class may sue or be sued as representative parties on behalf of all members only if the court finds all of the following: (a) The class is so numerous that joinder of all members is impracticable.(b) There are questions of law or fact common to the class.(c) The claims or defenses of the representative parties are typical of the claims or defenses of the class.(d) The representative parties will fairly and adequately protect the interests of the class.(2) TYPES OF CLASS ACTIONS. A class action may be maintained if sub. (1) is satisfied and if the court finds that any of the following are satisfied: (a) Prosecuting separate actions by or against individual class members would create a risk of either of the following:1. Inconsistent or varying adjudications with respect to individual class members that would establish incompatible standards of conduct for the party opposing the class.2. Adjudications with respect to individual class members that, as a practical matter, would be dispositive of the interests of the other members not parties to the individual adjudications or would substantially impair or impede their ability to protect their interests.(b) The party opposing the class has acted or refused to act on grounds that apply generally to the class, so that final injunctive relief or corresponding declaratory relief is appropriate respecting the class as a whole.(c) The court finds that the questions of law or fact common to class members predominate over any questions affecting only individual members, and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversy. The matters pertinent to these findings include all of the following: 1. The class members' interests in individually controlling the prosecution or defense of separate actions.2. The extent and nature of any litigation concerning the controversy already begun by or against class members.3. The desirability or undesirability of concentrating the litigation of the claims in the particular forum.4. The likely difficulties in managing a class action.(3) CERTIFICATION ORDER. (a)Time to issue. At an early practicable time after a person sues or is sued as a class representative, the court must determine by order whether to certify the action as a class action.(b)Defining the class; appointing class counsel. An order that certifies a class action must define the class and the class claims, issues, or defenses, and must appoint class counsel under sub. (12).(c)Altering or amending the order. An order that grants or denies class certification may be altered or amended before final judgment.(4) NOTICE. (a)For sub. (2) (a) or (b) classes. For any class certified under sub. (2) (a) or (b), the court may direct appropriate notice to the class.(b)For sub. (2) (c) classes. For any class certified under sub. (2) (c), the court must direct to class members the best notice that is practicable under the circumstances, including individual notice to all members who can be identified through reasonable effort. The notice must clearly and concisely state in plain, easily understood language, all of the following: 1. The nature of the action.2. The definition of the class certified.3. The class claims, issues, or defenses.4. That a class member may enter an appearance through an attorney if the member so desires.5. That the court will exclude from the class any member who requests exclusion.6. The time and manner for requesting exclusion.7. The binding effect of a class judgment on members under sub. (5).(5) JUDGMENT. Whether or not favorable to the class, the judgment in a class action must do one of the following: (a) For any class certified under sub. (2) (a) or (b), include and describe those whom the court finds to be class members.(b) For any class certified under sub. (2) (c), include and specify or describe those to whom the notice under sub. (4) was directed, who have not requested exclusion, and whom the court finds to be class members.(6) PARTICULAR ISSUES. Notwithstanding ss. 805.05(2) and 805.09(2) , when appropriate, an action may be brought or maintained as a class action with respect to particular issues.(7) SUBCLASSES. When appropriate, a class may be divided into subclasses that are each treated as a class under this rule.(8) CONDUCTING THE ACTION. (a)In general. In conducting an action under this section, the court may issue orders that do any of the following:1. Determine the course of proceedings or prescribe measures to prevent undue repetition or complication in presenting evidence or argument.2. Require - to protect class members and fairly conduct the action - giving appropriate notice to some or all class members of any of the following: a. Any step in the action.b. The proposed extent of the judgment.c. The members' opportunity to signify whether they consider the representation fair and adequate, to intervene and present claims or defenses, or to otherwise come into the action.3. Impose conditions on the representative parties or on intervenors.4. Require that the pleadings be amended to eliminate allegations about representation of absent persons and that the action proceed accordingly.5. Deal with similar procedural matters.(b)Combining and amending orders. An order under sub. (8) (a) may be altered or amended from time to time and may be combined with an order under s. 802.10 .(9) SETTLEMENT, VOLUNTARY DISMISSAL, OR COMPROMISE. The claims, issues, or defenses of a certified class may be settled, voluntarily dismissed, or compromised only with the court's approval. All of the following procedures apply to a proposed settlement, voluntary dismissal, or compromise: (a) The court must direct notice in a reasonable manner to all class members who would be bound by the proposal.(b) If the proposal would bind class members, the court may approve it only after a hearing and on finding that it is fair, reasonable, and adequate.(c) The parties seeking approval must file a statement identifying any agreement made in connection with the proposal.(d) If the class action was previously certified under sub. (2) (c), the court may refuse to approve a settlement unless it affords a new opportunity to request exclusion to individual class members who had an earlier opportunity to request exclusion but did not do so.(e) Any class member may object to the proposal if it requires court approval under sub. (9); the objection may be withdrawn only with the court's approval.(10) DISPOSITION OF RESIDUAL FUNDS. (a) In this subsection: 1. "Residual funds" means funds that remain after the payment of all approved class member claims, expenses, litigation costs, attorney fees, and other court-approved disbursements in an action under this section.2. "WisTAF" means the Wisconsin Trust Account Foundation, Inc.(b)1. Any order entering a judgment or approving a proposed compromise of a class action that establishes a process for identifying and compensating members of the class shall provide for disbursement of any residual funds. In class actions in which residual funds remain, not less than 50 percent of the residual funds shall be disbursed to WisTAF to support direct delivery of legal services to persons of limited means in non-criminal matters. The circuit court may disburse the balance of any residual funds beyond the minimum percentage to WisTAF for purposes that have a direct or indirect relationship to the objectives of the underlying litigation or otherwise promote the substantive or procedural interests of members of the certified class.2. This subsection does not prohibit the trial court from approving a settlement that does not create residual funds.(11) INTERLOCUTORY APPEAL OF CLASS CERTIFICATION. (a) When practicable after the commencement of an action brought as a class action, the court shall determine by order whether it is to be so maintained. If the court finds that the action should be maintained as a class action, it shall certify the action accordingly on the basis of a written decision setting forth all reasons why the action may be maintained and describing all evidence in support of the determination. An order under this subsection may be altered, amended, or withdrawn at any time before the decision on the merits. The court may direct appropriate notice to the class.(b) An appellate court shall hear an appeal of an order granting or denying class action certification, or denying a motion to decertify a class action, if a notice of appeal is filed within 14 days after entry of the order. During the pendency of an appeal under this subsection, all discovery and other proceedings shall be stayed, except that the trial court shall retain sufficient jurisdiction over the case to consider and implement a settlement of the action if a settlement is reached between the parties.(12) CLASS COUNSEL. (a)Appointing class counsel. Unless a statute provides otherwise, a court that certifies a class must appoint class counsel.(b)1. In appointing class counsel, the court must consider all of the following: a. The work counsel has done in identifying or investigating potential claims in the action.b. Counsel's experience in handling class actions, other complex litigation, and the types of claims asserted in the action.c. Counsel's knowledge of the applicable law.d. The resources that counsel will commit to representing the class.2. In appointing class counsel, the court may do any of the following: a. Consider any other matter pertinent to counsel's ability to fairly and adequately represent the interests of the class.b. Order potential class counsel to provide information on any subject pertinent to the appointment and to propose terms for attorney fees and nontaxable costs.c. Include in the appointing order provisions about the award of attorney fees or nontaxable costs under sub. (13).d. Make further orders in connection with the appointment.(c)Standard for appointing class counsel. When one applicant seeks appointment as class counsel, the court may appoint that applicant only if the applicant is adequate under sub. (12) (a) and (d). If more than one adequate applicant seeks appointment, the court must appoint the applicant best able to represent the interests of the class.(d)Interim counsel. The court may designate interim counsel to act on behalf of a putative class before determining whether to certify the action as a class action.(e)Duty of class counsel. Class counsel must fairly and adequately represent the interests of the class.(13) ATTORNEY FEES AND NONTAXABLE COSTS. In a certified class action, the court may award reasonable attorney fees and nontaxable costs that are authorized by law or by the parties' agreement. All of the following procedures apply: (a) A claim for an award must be made by motion, subject to the provisions of this subsection, at a time the court sets. Notice of the motion must be served on all parties and, for motions by class counsel, directed to class members in a reasonable manner.(b) A class member, or a party from whom payment is sought, may object to the motion.(c) The court may hold a hearing and must find the facts and state its legal conclusions under s. 805.17(2) .(d) The court may refer issues related to the amount of the award to a referee, as provided in s. 805.06 .(14) PROHIBITION AGAINST CERTAIN CLASS ACTIONS. No claim may be maintained against the state or any other party under this section if the relief sought includes the refund of or damages associated with a tax administered by the state.Amended by Acts 2018 ch, 235,s 8, eff. 7/1/2018.Sup. Ct. Order, 67 Wis. 2d 585, 650 (1975); 2011 a. 68. The class action statute, s. 260.12 [now s. 803.08], is part of title XXV of the statutes [now chs. 801 to 823], and the scope of title XXV is restricted to civil actions in courts of record. The county board is not a court of record. The class action statute can have no application to making claims against a county. Multiple claims must identify each claimant and show each claimant's authorization. Hicks v. Milwaukee County, 71 Wis. 2d 401, 238 N.W.2d 509 (1974). But see Townsend v. Neenah Joint School District, 2014 WI App 117, 358 Wis. 2d 618, 856 N.W.2d 644, 13-2839. The trial court did not abuse its discretion in determining that an action for damages caused by the negligent withdrawal of groundwater was not an appropriate class action. Nolte v. Michels Pipeline Const. Inc., 83 Wis. 2d 171, 265 N.W.2d 482 (1978). The test of common interest to maintain a class action is whether all members of the purported class desire the same outcome that their alleged representatives desire. Goebel v. First Federal Savings & Loan Ass'n, 83 Wis. 2d 668, 266 N.W.2d 352 (1978). The maintenance of a class action involving nonresident class members does not exceed the constitutional limits of the jurisdiction of the courts of this state. The due process requisites for the exercise of jurisdiction over unnamed nonresident plaintiffs are adequate notice and representation. Schlosser v. Allis-Chalmers Corp., 86 Wis. 2d 226, 271 N.W.2d 879 (1978). The trial court must decide if the named plaintiffs can fairly represent the common class interest that they share with the represented class and if joinder of all members is impracticable. O'Leary v. Howard Young Medical Center, 89 Wis. 2d 156, 278 N.W.2d 217 (Ct. App. 1979). To bring a class action: 1) there must be a common or general interest shared by all members of the class; 2) the named parties must represent the interest involved; and 3) it must be impractical to bring all interested parties before the court. Mercury Record v. Economic Consultants, 91 Wis. 2d 482, 283 N.W.2d 613 (Ct. App. 1979). In addition to considering the Mercury factors, the trial court must weigh the advantages of disposing of the entire controversy in one proceeding against the difficulties of combining divergent issues and persons. Cruz v. All Saints Healthcare System, Inc., 2001 WI App 67, 242 Wis. 2d 432, 625 N.W.2d 344, 00-1473. The trial court did not err when it determined that a proposed class of "tens of thousands of presently and formerly employed hourly paid Wal-Mart employees" should not be certified because, among other reasons, the proposed class would be unmanageable, recognizing that much of the pertinent Wal-Mart payroll records were generated in the first instance by members of the proposed class and that, therefore, Wal-Mart had a right to examine each individual claimant regarding the circumstances of his or her employment, and each instance of missed break time or off-the-clock work. Hermanson v. Wal Mart Stores, Inc., 2006 WI App 36, 290 Wis. 2d 225, 711 N.W.2d 694, 04-2926. Nothing in Wisconsin law bars class action against a governmental body that is a mass action of named claimants bringing similar claims, provided that each claimant has complied with s. 893.80. Townsend v. Neenah Joint School District, 2014 WI App 117, 358 Wis. 2d 618, 856 N.W.2d 644, 13-2839. The revised class certification rule directs courts to look to federal case law for guidance. Federal appellate courts review class certification decisions deferentially, in recognition of the fact that Federal Rule of Civil Procedure 23 gives the district courts broad discretion to determine whether certification of a class action lawsuit is appropriate. Federal appellate courts will reverse a class certification decision only when they find an abuse of discretion. Thus, a trial court's decision to grant or deny a motion for class certification is committed to the trial court's discretion. Harwood v. Wheaton Franciscan Services, Inc., 2019 WI App 53, 388 Wis. 2d 546, 933 N.W.2d 654, 18-1836. Sub. (1) requires a plaintiff to first establish three facts about the proposed class and the representativereferred to as numerosity, commonality, and typicalityand one fact about the plaintiff's ability to represent the class. Under sub. (2) (c), a trial court must find that the questions of law or fact common to class members predominate over any questions affecting only individual members and that a class action is superior to other available methods for fairly and efficiently adjudicating the controversyreferred to as the predominancy and superiority requirements. Harwood v. Wheaton Franciscan Services, Inc., 2019 WI App 53, 388 Wis. 2d 546, 933 N.W.2d 654, 18-1836. Viewpoint: A Call to Reform Wisconsin's Class-Action Statute. Benson, Olson, & Kaplan. Wis.
