Striking TCPA Class Allegations Before Discovery: What Works
Sometimes. Federal Rule 23 tells a court to decide certification “at an early practicable time,” and the Supreme Court has said in Falcon that “sometimes the issues are plain enough from the pleadings.” A TCPA complaint that defines its class in a way no discovery could rescue can be challenged right away. The risk is picking the wrong motion. Rule 12(f) is the one defendants reach for first, and the Ninth Circuit has limited what it can do.
Which motion actually fits?
Three different rules get used for this, and they aren’t interchangeable.
Rule 12(f) lets a court strike matter from a pleading. The rule says: “The court may strike from a pleading an insufficient defense or any redundant, immaterial, impertinent, or scandalous matter,” per Federal Rule of Civil Procedure 12(f). The Ninth Circuit has held that this has limits. In Whittlestone, Inc. v. Handi-Craft Co., 618 F.3d 970 (9th Cir. 2010), the court wrote: “We hold that Rule 12(f) of the Federal Rules of Civil Procedure does not authorize a district court to dismiss a claim for damages on the basis it is precluded as a matter of law.” That case wasn’t about class allegations, but a plaintiff will cite it whenever a defendant uses Rule 12(f) to argue that a class claim fails as a matter of law.
Rule 23 supplies the better footing. Under Rule 23(c)(1)(A), “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.” And Rule 23(d)(1)(D) allows the court to “require that the pleadings be amended to eliminate allegations about representation of absent persons and that the action proceed accordingly.” A motion framed under those provisions asks the court to do what the rule already contemplates.
The third route is Rule 12(b)(6), which tests whether the claim is plausible. It doesn’t reach class allegations directly, but it can remove the individual claim the class rides on. I’d pair it with the Rule 23 motion when the named plaintiff’s own claim has a hole.
What did the Supreme Court say about deciding early?
In General Telephone Co. of Southwest v. Falcon, the Court wrote: “Sometimes the issues are plain enough from the pleadings to determine whether the interests of the absent parties are fairly encompassed within the named plaintiff’s claim, and sometimes it may be necessary for the court to probe behind the pleadings before coming to rest on the certification question.”
Both halves of that sentence matter to a defendant. The first half supports an early motion. The second half is what the plaintiff will quote in response: the court may need discovery before it can say. In a TCPA case the plaintiff will add that call records, consent files, and vendor data sit with the defendant, and that argument has real force when the class depends on those records. A motion works best when the defect appears on the face of the class definition and doesn’t depend on facts the defendant controls.
Has the Ninth Circuit allowed a pleading-stage dismissal?
Yes, in a different kind of case. In Kamm v. California City Development Co., 509 F.2d 205 (9th Cir. 1975), the defendants asked the district court to dismiss the class action and strike the class allegations because a class action was not the superior method. The district court denied the plaintiffs’ request for more discovery and dismissed the class aspects. The Ninth Circuit affirmed: “Considering only those facts properly before the court, we conclude that the court did not abuse its discretion in dismissing the class action.”
I’d read Kamm as permission to ask, not a promise of success. The ruling rests on discretion, and the same opinion quotes a First Circuit warning in a footnote that “To pronounce finally, prior to allowing any discovery, the nonexistence of a class or set of subclasses, when their existence may depend on information wholly within defendants’ ken, seems precipitate and contrary to the pragmatic spirit of Rule 23.” Courts differ in how much they credit each side of that tension, and the district judge’s habits will matter.
What class-definition defects should a TCPA defendant look for?
Three come up often in complaints I’d expect to see, and each is something the defendant can point to on the page.
The first is a definition that depends on the merits. A class defined as everyone who received a text without consent can’t be counted without deciding consent for each person, which is the issue the case is about. A court may find that membership can’t be determined from the pleading. The second is a class that sweeps in people whose claim differs, such as people who gave consent through a form the complaint says nothing about. The third is a Do Not Call class that includes both people on the Registry and people who are not, or both landlines and cell phones.
None of these wins every time. A court may respond by narrowing the definition and letting the case go forward, which is why I’d count the motion as a way to force the plaintiff to commit to a definition early, even when the case survives. That has value of its own, because a plaintiff who has to defend a narrower class in writing is less free to argue a broader one at certification, and the judge will remember what the plaintiff said the first time.
| Vehicle | Rule | Best use | Main risk |
|---|---|---|---|
| Motion to strike | Rule 12(f) | A discrete, immaterial matter in the pleading | Whittlestone limits it, and the court may call it a merits dismissal |
| Motion to deny certification early | Rule 23(c)(1)(A) | A defect plain from the pleading | The court may wait for discovery under Falcon |
| Motion to amend pleadings | Rule 23(d)(1)(D) | Eliminating class allegations that can’t proceed | Court discretion |
| Motion to dismiss | Rule 12(b)(6) | Failure of the named plaintiff’s own claim | Doesn’t test the class |
How should the first motion be sequenced?
I’d put the cheapest, clearest argument first. If the named plaintiff’s own claim fails, that ends the class too, and a motion to dismiss says so without asking the judge to rule on anything about absent persons. If the individual claim survives, the class-definition motion is the second step, and it reads better when the court has already seen that the defendant isn’t stalling.
Also decide who signs the declaration. A pleading-stage motion that leans on a declaration from a records custodian invites the plaintiff to say the court can’t consider it yet. A motion that stays on the face of the complaint avoids that fight, and if you need facts, say so and ask for early, limited discovery on the class issue instead.
What to gather before filing
- Read the class definition against your records and mark every category of person it would include that you could exclude on paper.
- Collect the consent forms, opt-out logs, and campaign lists that show who the definition would capture, so you can describe the problem accurately.
- Decide in advance whether you want the court to rule early or want the plaintiff to commit to a definition, since the two goals call for different briefs.
- Prepare a short declaration on the facts the motion needs, and keep it limited, because a court deciding a pleading motion won’t weigh evidence.
- Talk to a lawyer before filing, because an early loss can shape how the judge sees certification later.

Questions defendants ask about challenging class allegations early
Is a motion to strike class allegations the same as a motion to dismiss?
No. Rule 12(f) addresses matter in a pleading, and the Ninth Circuit has refused to let it work as a merits dismissal in Whittlestone. A motion to dismiss tests whether a claim is plausible. A Rule 23 motion asks the court to decide whether the class can proceed.
Do we have to file the motion at the start of the case?
The timing rules differ by vehicle. Rule 12(f) motions have a short window set by the rule. Rule 23 motions can be made later, and the court itself must decide certification at an early practicable time. I’d file early if the defect is obvious.
Will the court let the plaintiff take discovery first?
Often, yes. Falcon says the court may need to probe behind the pleadings, and Kamm shows a district court can go the other way. Expect the plaintiff to ask for discovery and to say the facts are in your hands.
Can we use this if the plaintiff files in California state court?
State-court class procedure is different, and the federal rules discussed here govern federal cases. Removal changes the picture, so check which court you’re in.
