Jana and Ryan John appeal the dismissal of their class allegations. Finding no error, we affirm.
I.
The Johns were homeowners insured by National Security Fire and Casualty Company (“National Security”) when their house was damaged by Hurricane Rita. They allege that National Security violated the terms of the policies it issued in Louisiana by systematically under-adjusting damages claims by failing to account for the inevitable inflation in the price of labor and materials for home repair that follows from natural disasters. They also assert that National Security violated the terms of homeowners’ policies that it issued in Louisiana by systematically failing to account for general contractors’ overhead and profit (“GCO&P”) when repair required the exercise of two or more trades.
The Johns sued for fraud and breach of contract, purporting to represent all similarly situated persons insured by National Security. In their amended complaint the Johns alleged the following class:
All persons and/or entities insured by NATIONAL SECURITY under a homeowner’s insurance policy, including tenant and condominium policies, or commercial property insurance policy:
(I) who sustained property damages to dwellings, buildings or other structures located in the State of Louisiana on or after August 29, 2005, as a result of hurricanes Katrina and Rita, or otherwise; and
(ii) whose losses were adjusted by or on behalf of NATIONAL SECURITY on an “actual cash value” basis or “replacement cost” basis, and
(in) for whom NATIONAL SECURITY and/or its agent or contractor created a damages assessment, worksheet, or estimate of costs to repair or replace said damaged property that indicates the involvement of more than one trade. 1
Responding to National Security’s motion, the district court dismissed the Johns’ fraud allegations pursuant to Federal Rule of Civil Procedure 9(b) and dismissed their class allegation pursuant to Federal Rule of Civil Procedure 12(b)(6) for failure to plead an ascertainable class. Although the *445 court denied the Johns’ motion for reconsideration, it certified its dismissal of the class allegation for interlocutory appeal pursuant to 28 U.S.C. 1292(b), and we granted leave to appeal.
II.
The question is whether the district court erred by dismissing the class allegation. On appeal, the Johns propose, for the first time, that the district court certify two separate classes: a so-called price fixing class and a GCO&P class. They do not argue in favor of certifying a unitary class, as they proposed in their amended complaint. Because our jurisdiction over this interlocutory appeal extends only to the order dismissing the alleged unitary class on the pleadings, we may not consider whether the court should have certified two separate classes that were never proposed to it. 2 Accordingly we do not address the Johns’ arguments in this regard. Because this ease is ongoing, they may amend their complaint pursuant to the district court’s discretion under Federal Rule of Civil Procedure 15, but they may not successfully propose a new class definition in this court.
The Johns are incorrect insofar as they argue that the district court erred because dismissal of a class allegation on the pleadings is never proper. The existence of an ascertainable class of persons to be represented by the proposed class representative is an implied prerequisite of Federal Rule of Civil Procedure 23. 3 Where it is facially apparent from the pleadings that there is no ascertainable class, a district court may dismiss the class allegation on the pleadings. 4 Because the Johns do not contend that the class they propose is ascertainable, but instead propose two newly defined classes, we need not determine whether they pleaded sufficient facts, in their complaint alleging an ascertainable class, to survive scrutiny under rule 12(b)(6). 5 Accordingly, the order dismissing the class allegations is AFFIRMED.
Notes
. In addition, the proposed class contained various exclusions so as to avoid purporting to represent the interests of government officials or law firms involved in the case.
