NOTICE OF MOTION AND MOTION

TO ALL PARTIES AND THEIR ATTORNEYS OF RECORD:

PLEASE TAKE NOTICE that on [__/__/____] at [________________________________], or as soon thereafter as the matter may be heard, in Department [________] of the above-entitled Court, located at [________________________________], Plaintiff [________________________________] ("Plaintiff") will and hereby does move this Court for an order certifying this action as a class action pursuant to California Code of Civil Procedure § 382 and California Rules of Court, Rules 3.764 through 3.766.

By this Motion, Plaintiff respectfully requests that the Court:

  1. Certify the proposed Class defined below pursuant to Cal. Code Civ. Proc. § 382;

  2. Appoint Plaintiff [________________________________] as the Class Representative;

  3. Appoint the undersigned, [________________________________], as Class Counsel;

  4. Define the claims, issues, and defenses to be treated on a classwide basis; and

  5. Direct the parties to meet and confer and submit a proposed form and plan of class notice consistent with Cal. Rules of Court, Rule 3.766.

This Motion is based on this Notice of Motion and Motion, the attached Memorandum of Points and Authorities, the Declaration(s) of [________________________________], the [Separate Statement / appendix of evidence], the pleadings and papers on file in this action, and any oral argument and evidence presented at or before the hearing.


MEMORANDUM OF POINTS AND AUTHORITIES

I. INTRODUCTION

This case presents precisely the kind of controversy California's class action procedure was designed to resolve in a single proceeding. Defendant engaged in a uniform course of conduct — [________________________________] — that affected every member of the proposed Class in the same way. Whether that conduct was unlawful can be litigated through common evidence applicable to the Class as a whole, and individual litigation of these claims would be economically irrational and would risk inconsistent results.

Plaintiff respectfully requests that the Court certify the following Class:

Class Definition: All persons in the State of California who [________________________________] during the period from [__/__/____] through [__/__/____] (the "Class Period").

Excluded from the Class: Defendant, its officers, directors, employees, agents, parents, subsidiaries, affiliates, and legal representatives; the judicial officers assigned to this litigation and members of their immediate families and staff; all persons who timely and validly request exclusion from the Class; and [________________________________].

III. LEGAL STANDARD

California Code of Civil Procedure § 382 authorizes class actions "when the question is one of a common or general interest, of many persons, or when the parties are numerous, and it is impracticable to bring them all before the court." Although § 382 is the statutory anchor, California courts have developed the governing standard through case law and the California Rules of Court.

To obtain certification, the party seeking it must establish the existence of (1) an ascertainable class and (2) a well-defined community of interest among the class members. Brinker Restaurant Corp. v. Superior Court, 53 Cal. 4th 1004, 1021 (2012); Sav-On Drug Stores, Inc. v. Superior Court, 34 Cal. 4th 319, 326 (2004). The "community of interest" requirement embodies three factors: "(1) predominant common questions of law or fact; (2) class representatives with claims or defenses typical of the class; and (3) class representatives who can adequately represent the class." Brinker, 53 Cal. 4th at 1021 (quoting Sav-On, 34 Cal. 4th at 326). The proponent must also show that class treatment will produce substantial benefits to the litigants and the courts that render proceeding as a class superior to the alternatives. Linder v. Thrifty Oil Co., 23 Cal. 4th 429, 435 (2000).

The trial court's decision is reviewed for abuse of discretion, and California courts have long recognized "the importance of class actions as a means to prevent a failure of justice in our judicial system." Linder, 23 Cal. 4th at 434; accord Sav-On, 34 Cal. 4th at 340. Although the court may consider the merits to the extent they overlap with the certification requirements, "[t]he certification question is essentially a procedural one that does not ask whether an action is legally or factually meritorious." Sav-On, 34 Cal. 4th at 326 (internal quotation marks omitted); see also Brinker, 53 Cal. 4th at 1023.

IV. ARGUMENT

A. The Proposed Class Is Ascertainable

A class is ascertainable when it is defined "in terms of objective characteristics and common transactional facts" that make "the ultimate identification of class members possible when that identification becomes necessary." Noel v. Thrifty Payless, Inc., 7 Cal. 5th 955, 980 (2019). A plaintiff need not prove at the certification stage that every class member can presently be located or identified; that evidentiary burden is not part of the ascertainability inquiry. Id. at 984-86.

Here, the Class is ascertainable because:

☐ The Class is defined by objective criteria, namely [________________________________];

☐ Membership can be determined from Defendant's business records, including [________________________________] (e.g., transaction logs, customer lists, sales/warranty databases);

☐ A prospective member could read the definition and determine whether he or she is included; and

☐ [________________________________].

B. The Class Satisfies the Community-of-Interest Requirement
1. Common Questions of Law and Fact Predominate

The "ultimate question" on predominance is "whether the issues which may be jointly tried, when compared with those requiring separate adjudication, are so numerous or substantial that the maintenance of a class action would be advantageous to the judicial process and to the litigants." Sav-On, 34 Cal. 4th at 326 (internal quotation marks omitted). "[A] class action is not inappropriate simply because each member of the class may at some point be required to make an individual showing as to . . . damages." Brinker, 53 Cal. 4th at 1022. The focus is on whether the theory of recovery is amenable to classwide proof. Id. at 1024-25.

Common questions predominate here because Defendant's conduct was uniform and the central liability questions are common to all members:

☐ Whether Defendant engaged in [________________________________];

☐ Whether Defendant's [representation/omission/practice] was unlawful, unfair, or likely to deceive a reasonable consumer;

☐ Whether Defendant's conduct caused classwide injury;

☐ Whether Plaintiff and the Class are entitled to restitution, damages, and/or injunctive relief;

☐ The appropriate measure of classwide relief; and

☐ [________________________________].

These common questions can be resolved with common evidence — [________________________________] — and predominate over any individualized issues. To the extent individual issues of damages or eligibility remain, they can be managed through [subclasses / claims procedures / representative or statistical evidence], consistent with Duran v. U.S. Bank National Assn., 59 Cal. 4th 1, 31-33 (2014).

2. Plaintiff's Claims Are Typical of the Class

Typicality requires that the representative's claims be "typical" of the class — they need not be identical, only arise from the same course of conduct and rest on the same legal theory. See Sav-On, 34 Cal. 4th at 332-33; Classen v. Weller, 145 Cal. App. 3d 27, 45 (1983). Plaintiff's claims are typical because:

☐ Plaintiff was subjected to the same conduct by Defendant as the Class;

☐ Plaintiff's claims arise from the same course of conduct and the same legal theories;

☐ Plaintiff suffered the same type of injury as the Class; and

☐ [________________________________].

3. Plaintiff and Counsel Will Adequately Represent the Class

Adequacy requires that the representative not have a conflict with the class and that the representative and counsel will vigorously prosecute the action. See McGhee v. Bank of America, 60 Cal. App. 3d 442, 450 (1976).

Adequacy of the Class Representative. Plaintiff is adequate because:

☐ Plaintiff has no interests antagonistic to or in conflict with the Class;

☐ Plaintiff has a genuine stake in the outcome and understands the duties of a class representative;

☐ Plaintiff has participated in the prosecution of this case; and

☐ [________________________________]. See Declaration of [________________________________], ¶¶ [____].

Adequacy of Proposed Class Counsel. Proposed Class Counsel is qualified because:

☐ Counsel has extensive experience in class action and complex litigation;

☐ Counsel has successfully prosecuted similar actions;

☐ Counsel has committed and will commit the resources necessary to represent the Class; and

☐ [________________________________]. See Declaration of [________________________________] (counsel résumé and case history), Exhibit [____].

C. Class Treatment Will Yield Substantial Benefits (Superiority)

A class action is superior, and will yield substantial benefits to the courts and litigants, because the alternative — individual litigation by [________________________________] persons over relatively small recoveries — is impracticable. Linder, 23 Cal. 4th at 435. Class treatment will:

☐ Provide an effective remedy where individual stakes are too small to justify separate suits;

☐ Avoid the risk of inconsistent adjudications;

☐ Conserve judicial resources through unitary adjudication of common questions; and

☐ [________________________________].

The action is manageable because Defendant's records permit efficient identification of and notice to Class members, and the common questions can be tried with common proof.

V. PROPOSED TRIAL PLAN AND CLASS NOTICE

A. Trial Plan

Plaintiff proposes to prove the Class's claims through the following common evidence and trial structure:

Liability (common phase): [________________________________];

Classwide proof: [documentary evidence / Defendant's records / expert testimony / representative testimony];

Relief: [classwide restitution / formulaic damages / claims process], with any individualized issues addressed through [________________________________];

Affirmative defenses: Defendant will retain the ability to contest [________________________________], consistent with Duran, 59 Cal. 4th at 31-33.

B. Class Notice

Upon certification, Plaintiff will submit a proposed notice and notice plan consistent with Cal. Rules of Court, Rule 3.766. The proposed plan will provide the best notice practicable under the circumstances and may include:

☐ Direct mail and/or email notice to members identifiable from Defendant's records;

☐ Publication notice in [________________________________];

☐ A dedicated case website; and

☐ [________________________________].

VI. CONCLUSION

For the foregoing reasons, Plaintiff respectfully requests that the Court grant this Motion and enter an order: (1) certifying the proposed Class under Cal. Code Civ. Proc. § 382; (2) appointing Plaintiff as Class Representative; (3) appointing the undersigned as Class Counsel; (4) defining the Class claims and issues; and (5) directing the parties to submit a proposed class notice under Cal. Rules of Court, Rule 3.766.

California Practice Notes

  • Governing authority. California class actions rest on Cal. Code Civ. Proc. § 382, supplemented by Cal. Rules of Court, Rules 3.760-3.771. Rule 3.764 governs the certification motion; Rule 3.766 governs notice.
  • Certification standard. California does not adopt federal Rule 23 verbatim. The proponent must show (1) an ascertainable class and (2) a well-defined community of interest — predominant common questions, typicality, and adequacy — plus substantial benefits from class treatment (the analog to superiority). Brinker, 53 Cal. 4th at 1021; Sav-On, 34 Cal. 4th at 326; Linder, 23 Cal. 4th at 435.
  • Predominance focuses on the theory of recovery. Brinker directs courts to assess whether the elements of the claim are susceptible to common proof; the need for individualized damages does not defeat certification. 53 Cal. 4th at 1022-25.
  • Ascertainability is objective. A class is ascertainable if defined by objective characteristics and common transactional facts; plaintiff need not show at certification how every member will be identified. Noel v. Thrifty Payless, Inc., 7 Cal. 5th 955 (2019).
  • Statistical/representative proof. Permissible, but a sampling-based trial plan must be statistically valid and must preserve the defendant's ability to litigate defenses. Duran v. U.S. Bank National Assn., 59 Cal. 4th 1 (2014).
  • Interlocutory appellate review. California follows the "death knell" doctrine: an order denying certification (or otherwise terminating class claims) is immediately appealable as a final judgment as to the class, while an order granting certification is generally reviewable only by discretionary writ petition (or on appeal from the final judgment). See Daar v. Yellow Cab Co., 67 Cal. 2d 695 (1967); In re Baycol Cases I & II, 51 Cal. 4th 751 (2011). Confirm the current state of the death-knell doctrine before relying on it; its scope is litigated.
  • Consumer-protection nuance. UCL (Bus. & Prof. Code § 17200) and CLRA (Civ. Code § 1750) claims are common vehicles for class treatment. Reliance and causation under the "fraudulent" UCL prong and the CLRA can often be shown on a classwide basis where a material misrepresentation was made uniformly, but defendants frequently contest predominance on individualized reliance — address this head-on. The CLRA has its own class provisions (Civ. Code § 1781).
  • Unsettled / flag. The precise contours of the death-knell doctrine, the use of aggregate damages models post-Duran, and classwide reliance under the UCL/CLRA are actively litigated. Tailor the record and brief these points to your facts.

About This Template

Class action lawsuits let a group of people with the same claim against the same defendant pursue relief together, usually because filing separately would be too expensive for each person. These cases require careful drafting to get the class certified, identify common questions of law or fact, and meet the procedural requirements for notice and settlement. Class action paperwork follows stricter rules than standard litigation, and getting any of them wrong can stall the case for months.

Important Notice
