law or fact common to the class, (3) the claims or defenses of the representative parties are typical of the claims or defenses of the class, and (4) the representative parties will fairly and adequately protect the interests of the class.
Fed.R.Civ.P. 23(a). Thus, as we have explained, “[t]he district court may certify a class of plaintiffs if the putative class satisfies all four requirements of Federal Rule of Civil Procedure 23(a)—numerosity, commonality, typicality, and adequacy of representation—and any one of the conditions of Rule 23(b).” Oshana v. Coca-Cola Co., 472 F.3d 506, 513 (7th Cir.2006) (citations omitted). In this case, plaintiffs sought certification under section 23(b)(3), which requires that “the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superior to other available methods for the fair and efficient adjudication of the controversy.” Fed.R.Civ.P. 23(b)(3). Plaintiffs bear the burden of proving that a class should be certified. Oshana, 472 F.3d at 513 (citation omitted).
The district court denied class certification because the plaintiffs failed to demonstrate that common issues predominate under Rule 23(b)(3). Specifically, the district court focused on the elements of a claim under ICFA, holding that establishing such a claim required individualized proof. Because of the need for individualized proof, the district court found that common class issues did not predominate. Plaintiffs argue that the website was deceptive per se, and therefore no individualized finding of proximate cause would be required.
We agree with the district court and our prior case law confirms that a claim under ICFA requires individualized proof. A claim for consumer fraud under the ICFA contains five elements: “(1) a deceptive act or practice by the defendant, (2) the defendant’s intent that the plaintiff rely on the deception, (3) the occurrence of the deception in the course of conduct involving trade or commerce, and (4) actual damage to the plaintiff (5) proximately caused by the deception.” Avery v. State Farm Mut. Auto. Ins. Co., 216 Ill.2d 100, 296 Ill.Dec. 448, 835 N.E.2d 801, 856 (2005) (citation omitted). Furthermore, “in a case alleging deception under the [Consumer Fraud] Act, it is not possible for a plaintiff to establish proximate causation unless the plaintiff can show that he or she was, ‘in some manner, deceived’ by the misrepresentation.” Id. at 861 (citation omitted). Satisfaction of this element requires individualized proof.
We previously considered and rejected the argument that per se deceptiveness absolves a plaintiff from making individualized proofs of proximate cause under the ICFA. See Oshana, 472 F.3d at 513-15. We concluded that “a private cause of action under the ICFA requires a showing of proximate causation.” Id. at 514-15 (citing 815 Ill. Comp. Stat. 505/10a; Oliveira v. Amoco Oil Co., 201 Ill.2d 134, 267 Ill.Dec. 14, 776 N.E.2d 151, 160 (2002) (“Unlike an action brought by the Attorney General under [815 111. Comp. Stat. 505/2], which does not require that ‘any person has in fact been misled, deceived or damaged[,]’... a private cause of action brought under [815 111. Comp. Stat. 505/10a] requires proof of ‘actual damage.’ ... [and] proof that the damage occurred ‘as a result of the deceptive act or practice.” (citations omitted))). Accordingly, to demonstrate proximate cause each member of the class would have to prove that the deceptive nature of the website caused each of them to enroll in the credit monitoring service and incur unwanted charges. Such causation cannot necessarily be inferred from the fact that the class is defined as members who did not access the service; individuals could have enrolled in
