The Fourth Circuit, on appeal from the Eastern District of Virginia, recently upheld the denial of class certification due to the unreliability of the plaintiff’s expert opinion regarding the ascertainability of putative class members. See Davis v. Capital One N.A., No. 22-0903, 2025 WL 2445880 (4th Cir. 2025).
The plaintiff allegedly received multiple prerecorded messages to his cell phone regarding an unpaid debt owed by a different consumer from whom the phone number had been reassigned. The calls allegedly continued even after the plaintiff called to inform Capital One that it had been calling the wrong person. The plaintiff eventually filed suit, asserting claims on behalf of himself and a nationwide class of unnamed consumers who had also received calls to reassigned numbers.
