As promised, here is the brief submitted by a second group of professors, together with former SEC Commissioners, in Halliburton Inc. v. Erica P. John Fund, Inc.
It argues that the Court “need not wade into the complex and highly technical debate over the efficient markets hypothesis to answer the question presented here. Instead, the Court can, and should, decide this case by applying well-established principles of statutory construction.” It argues that, to infer how the 1934 Congress would have addressed the issues had the 10b–5 action been included as an express provision in the 1934 Act, the Court should consult the express causes of action in the securities laws, and borrow from the most analogous one.

As originally drafted, Section 18(a) contained no reliance requirement, but Congress rejected that no reliance version in the face of a torrent of criticism. As enacted, Section 18(a) thus prohibits recovery “unless the buyer bought the security with knowledge of
