In a class action lawsuit against Altria Group over their Juul e-cigarettes, it likely came as no surprise that the class numbered in the millions. What may have been a shock, though, was that the number of claims received for a proposed settlement exceeded 14.4 million—almost five times more than expected. But, as plaintiff’s attorneys for the class action told the judge, over 80% of those were likely invalid or fraudulent.

Of course, fraud in class action claims is hardly new. But now, the scale of such malicious activity is reaching new heights.
