Erica P. John Fund, Inc. v. Halliburton Co., 09-1403

In a securities fraud class action against defendant alleging section 10(b) and Rule 10b-5 violations, judgment of the appeals court affirming denial of Rule 23(b)(3) certification on the ground that plaintiffs failed to prove loss causation is reversed because securities fraud plaintiffs need not prove loss causation in order to obtain class certification.
