On September 7, 2017, Business Roundtable filed an amicus brief in the Supreme Court of Delaware in the case of California State Teachers Retirement System et al. v. Aida M. Alvarez et al., arguing that the court should reject a decision by a lower state court (Chancery Court) that could potentially expand the number of derivative stockholders suits filed in multiple states.
The brief argued that the Supreme Court should not depart from existing doctrine and should instead reject the Chancery Court's ruling that would deny preclusive effect to non-Delaware decisions on demand futility in derivative litigation.
