This article explores the use of derivative actions by investors in hedge funds, which investors may bring against hedge fund managers, and explains that where a fund is organized determines whether an investor can maintain a derivative action.  This article also discusses investor requests for books and records relating to a hedge fund, which typically precede an investor’s derivative action.  The authors of this article are Thomas K. Cauley, Jr. and Courtney A. Rosen, both litigation partners in the Chicago office of Sidley Austin LLP.  See also “Contractual Provisions That Matter in Litigation between a Fund Manager and an Investor,” Hedge Fund Law Report, Vol. 7, No. 37 (Oct. 2, 2014).
