Issue:

Does Federal Rule of Civil Procedure 23(b)(3) require plaintiffs in a securities fraud class action to prove the element of loss causation in order to obtain class certification?


Opinions:

Majority - Chief Justice Roberts

No. Federal Rule of Civil Procedure 23(b)(3) does not require securities fraud plaintiffs to prove the element of loss causation in order to obtain class certification. The court's reasoning is that loss causation is a merits-based element of a securities fraud claim, separate and distinct from the element of reliance. The 'fraud-on-the-market' presumption established in Basic Inc. v. Levinson allows plaintiffs to satisfy the reliance element on a class-wide basis by showing they purchased stock at a market price that was distorted by a public misrepresentation. This presumption, which the court terms 'transaction causation,' ensures that common questions of fact will predominate for certification purposes. Loss causation, in contrast, addresses whether the misrepresentation was the ultimate cause of the investor's economic loss, which may have been caused by other intervening factors. Requiring proof of loss causation at the certification stage conflates the certification inquiry with a trial on the merits and contravenes the logic of Basic, which did not mention loss causation as a precondition for invoking the presumption of reliance.



Analysis:

This decision resolves a significant circuit split and lowers the procedural hurdle for plaintiffs seeking to certify a securities fraud class action. By definitively separating the merits question of loss causation from the procedural requirements of class certification, the Court makes it easier for such cases to proceed. This reinforces the principle that class certification is not a mini-trial on the ultimate merits of the case. The ruling strengthens the fraud-on-the-market theory's utility for plaintiffs by clarifying that its purpose is to establish a presumption of reliance ('transaction causation'), not to pre-prove the entirety of the causal chain leading to economic loss.
