PLAINTIFF'S MOTION FOR CLASS CERTIFICATION AND MEMORANDUM OF POINTS AND AUTHORITIES IN SUPPORT
NOTICE OF MOTION
PLEASE TAKE NOTICE that Plaintiff [________________________________] hereby moves, pursuant to D.C. Superior Court Civil Rule 23, for an order certifying this action as a class action. Pursuant to Superior Court Civil Rule 12-I, any opposition must be filed within 14 days after service of this Motion. A proposed order is submitted herewith.
THE MOTION
Plaintiff [________________________________] ("Plaintiff"), individually and on behalf of all others similarly situated, respectfully moves this Court for an Order:
-
Certifying this action as a class action pursuant to D.C. Superior Court Civil Rule 23(a) and 23(b)(3) [and/or 23(b)(1) and/or 23(b)(2)];
-
Appointing Plaintiff [________________________________] as Class Representative;
-
Appointing [________________________________] and [Firm Name] as Class Counsel pursuant to Rule 23(g); and
-
Approving Plaintiff's proposed form and manner of class notice under Rule 23(c)(2).
This Motion is based on this Motion, the accompanying Memorandum of Points and Authorities, the Declaration(s) of [________________________________], the pleadings and papers on file, and any evidence and argument presented at the hearing on this Motion.
Proposed Class Definition
Plaintiff seeks certification of the following Class:
All persons in the District of Columbia who [________________________________] during the period from [__/__/____] through [__/__/____] (the "Class Period").
Plaintiff also seeks certification of the following Subclass(es), if appropriate:
Excluded from the Class are: 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; persons who timely and validly request exclusion; and [________________________________].
MEMORANDUM OF POINTS AND AUTHORITIES
I. INTRODUCTION
This action presents classic grounds for class treatment under Superior Court Civil Rule 23. Defendant engaged in standardized conduct affecting [________________________________] in a uniform manner, and the central questions — whether that conduct was unlawful and whether it caused classwide injury — can be resolved with common, generalized proof. Individual litigation would be impracticable and uneconomical. Certification is the superior vehicle for adjudicating this controversy.

III. LEGAL STANDARD
Class certification in the Superior Court is governed by D.C. Superior Court Civil Rule 23, which is substantially identical to Federal Rule of Civil Procedure 23. The D.C. Court of Appeals "look[s] to federal court decisions interpreting [Rule 23] as persuasive authority." Ford v. ChartOne, Inc., 908 A.2d 72, 80-81 (D.C. 2006). A plaintiff must satisfy all four prerequisites of Rule 23(a) — numerosity, commonality, typicality, and adequacy — and at least one subdivision of Rule 23(b).
The plaintiff bears the burden of proving that the Rule 23 prerequisites are satisfied, and the trial court must conduct a "rigorous analysis," which may overlap with the merits. Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338, 350-51 (2011). Commonality requires that the class claims "depend upon a common contention" capable of "classwide resolution." Id. at 350. For a Rule 23(b)(3) class, common questions must predominate, and the plaintiff must present a damages methodology consistent with its theory of liability. Comcast Corp. v. Behrend, 569 U.S. 27, 35 (2013).
IV. ARGUMENT
A. The Proposed Class Satisfies Rule 23(a)
1. Numerosity — Rule 23(a)(1)
Rule 23(a)(1) requires that "the class is so numerous that joinder of all members is impracticable."
☐ The proposed Class consists of approximately [________________________________] members.
☐ Evidence supporting numerosity: [________________________________].
☐ Joinder is impracticable because: [________________________________].
The number and identities of Class members are ascertainable from Defendant's records.
2. Commonality — Rule 23(a)(2)
Rule 23(a)(2) requires "questions of law or fact common to the class." Common questions include:
☐ Whether Defendant engaged in [________________________________];
☐ Whether Defendant's conduct was unlawful, unfair, or deceptive;
☐ Whether Defendant's uniform [representation/omission/practice] applied to the Class;
☐ Whether Class members suffered injury as a result;
☐ The appropriate measure of damages or other relief;
☐ [________________________________]
These questions are capable of classwide resolution because their truth or falsity will resolve issues central to each member's claim "in one stroke." Dukes, 564 U.S. at 350.
3. Typicality — Rule 23(a)(3)
Rule 23(a)(3) requires that the representative's claims be "typical of the claims or defenses of the class." Plaintiff's claims arise from the same conduct and legal theories as the Class:
☐ Plaintiff was subjected to the same conduct as Class members;
☐ Plaintiff's claims arise from the same course of conduct by Defendant;
☐ Plaintiff's legal theories are identical to those of the Class;
☐ [________________________________]
4. Adequacy — Rule 23(a)(4)
Rule 23(a)(4) requires that "the representative parties will fairly and adequately protect the interests of the class."
a. Adequacy of the Class Representative. Plaintiff has no conflicts with the Class, has a sufficient stake in the outcome, and is committed to vigorously prosecuting this action. See Declaration of [________________________________], Ex. [____].
b. Adequacy of Class Counsel. Proposed Class Counsel are experienced in complex class litigation, have committed adequate resources, and satisfy the factors of Rule 23(g). See Declaration of [________________________________], Ex. [____].
B. The Proposed Class Satisfies Rule 23(b)(3): Predominance and Superiority
Rule 23(b)(3) requires that common questions "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."
1. Predominance
Common questions predominate because liability turns on Defendant's uniform conduct, provable through common evidence:
☐ Defendant's conduct was standardized across the Class;
☐ Liability can be established through common proof;
☐ Damages can be calculated classwide using [________________________________];
☐ Individual issues, if any, are manageable through subclasses or individualized post-liability proceedings;
☐ [________________________________]
Plaintiff's damages methodology measures only the harm attributable to Defendant's alleged wrongful conduct and is consistent with Plaintiff's theory of liability. See Expert Report of [________________________________], Ex. [____]; Comcast, 569 U.S. at 35.
2. Superiority
A class action is superior because:
☐ Individual control: Class members' individual stakes are small relative to the cost of litigation;
☐ Other litigation: Plaintiff is not aware of other pending litigation by Class members concerning this controversy [or: [________________________________]];
☐ Desirability of this forum: [________________________________];
☐ Manageability: Common issues predominate, Class members are identifiable from Defendant's records, and efficient notice is feasible.
C. Alternative: Certification Under Rule 23(b)(1) and/or (b)(2)
☐ Rule 23(b)(1): Separate actions would risk inconsistent adjudications establishing incompatible standards of conduct for Defendant, or would be dispositive of non-party members' interests.
☐ Rule 23(b)(2): Defendant acted or refused to act on grounds generally applicable to the Class, making final injunctive or corresponding declaratory relief appropriate as to the Class as a whole.
D. The Class Is Ascertainable
The proposed Class is defined by objective criteria and is ascertainable from Defendant's business records, including [________________________________]. Class membership does not depend on resolution of any merits question.
V. PROPOSED TRIAL PLAN AND CLASS NOTICE
A. Trial Plan
Plaintiff proposes to try the common liability questions on a classwide basis using the common evidence identified above, followed by [________________________________] for the determination of relief. A proposed trial plan is attached as Ex. [____].
B. Class Notice
For a class certified under Rule 23(b)(3), Plaintiff will provide the best notice practicable under the circumstances, including individual notice to members identifiable through reasonable effort. The proposed notice (Ex. [____]) describes the nature of the action, the class definition, the claims and defenses, the right to enter an appearance through counsel, the right and procedure to request exclusion, and the binding effect of a class judgment, consistent with Rule 23(c)(2).
☐ Direct mail notice to identifiable Class members;
☐ Email notice where addresses are known;
☐ Publication notice in [________________________________];
☐ Dedicated case website;
☐ [________________________________]
VI. CONCLUSION
For the foregoing reasons, Plaintiff respectfully requests that the Court certify the proposed Class under Rule 23(a) and 23(b)(3) [and/or (b)(1)/(b)(2)], appoint Plaintiff as Class Representative, appoint the undersigned as Class Counsel under Rule 23(g), and approve the proposed form and manner of class notice.

District of Columbia Practice Notes
- Governing rule. D.C. Superior Court Civil Rule 23 governs class actions in the Superior Court and is substantially identical to Federal Rule 23 (with minor differences in (c)(1)–(c)(2)). The D.C. Court of Appeals construes Rule 23 by reference to federal authority. Ford v. ChartOne, Inc., 908 A.2d 72 (D.C. 2006).
- Certification standard. Plaintiff bears the burden; the court conducts a "rigorous analysis" that may overlap with the merits. Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338 (2011); for predominance and damages, Comcast Corp. v. Behrend, 569 U.S. 27 (2013).
- Consumer-class nuance. The D.C. Consumer Protection Procedures Act (CPPA), D.C. Code § 28-3905(k), authorizes representative and class claims and is frequently used in D.C. consumer class litigation. A CPPA representative claim is subject to Rule 23 when brought on behalf of a class; confirm the interplay between the CPPA's representative-action provisions and Rule 23 for the specific claims pleaded.
- Interlocutory appeal. Unlike federal Rule 23(f), D.C. Superior Court Civil Rule 23 contains no express provision for discretionary interlocutory appeal of class-certification orders. Review of a certification order is generally available only after final judgment, although a party may seek discretionary review by the D.C. Court of Appeals under D.C. Code § 11-721(d) (certified interlocutory appeals) or by petition for an extraordinary writ in rare circumstances. Treat early appellate review as the exception, and flag this point for the reviewing attorney.
- Key cases. Ford v. ChartOne, Inc., 908 A.2d 72 (D.C. 2006) (Rule 23 analysis; federal authority persuasive); Dukes and Comcast (persuasive federal standards applied in D.C. courts).

This template is for informational purposes only and does not constitute legal advice. D.C. class certification practice — including the absence of a Rule 23(f)-style interlocutory appeal and the CPPA's representative-action provisions — has traps for the unwary. Consult experienced District of Columbia class action counsel before filing.
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
