In brief

Overview

Petitioners argue that affirming the lower‑court judgment would authorize private securities‑fraud class actions against every service provider that participates in the drafting of a public company’s prospectus.

The Court is considering who the alleged violator is and how the concepts of “primary violator” and the SEC’s Rule 20(b) apply to liability under §10(b).

Background and question before the Court

Mr. Frederick (representing Respondent) argues that the advisers did not have substantive control over the false statements in the prospectus.

The Court is asked to determine whether liability can extend to indirect actors under Rule 20(b) even when no primary violator is identified.

What each side argues

Petitioners’ Position

According to Petitioners, affirming the judgment would expand liability to any service provider that drafts a prospectus.

According to Mr. Perry, the funds are governed by trustees, a fact disclosed in the prospectus.

According to Mr. Frederick, the advisers did not have substantive control over the false statements; otherwise they would have prevented them.

According to Petitioners (Mr. Perry), according to Petitioners (Mr. Perry), Rule 20(b) permits the SEC to pursue indirect actors without requiring a primary violator.

According to Petitioners (Mr. Gannon), according to Petitioners (Mr. Gannon), the situation is analogous to corporate employees drafting statements issued in the company’s name; liability should be limited to private suits under §10(b).

What the Court decided

Pending This section will be added when the relevant Court material is available.

Why it matters

According to Petitioners, the case could broaden securities‑fraud liability to include service providers that help draft prospectuses, affecting many financial‑industry participants.

Curtis E. Gannon argued that a primary violator must be somebody who has actually committed all the elements of a 10b‑5 cause of action.

According to Petitioners (Mr. Perry), according to Petitioners (Mr. Perry), interpretation of Rule 20(b) could allow the SEC to pursue indirect actors without identifying a primary violator, expanding the agency’s enforcement reach.
