Mark Delaney – Of Counsel

Mark focuses his practice on protecting the rights of investors and has represented corporate whistleblowers who have exposed significant investor frauds and corporate malfeasance, leading to successful SEC investigations which resulted in large awards for the whistleblowers.  He has also represented a whistleblower in a lawsuit against his former employer for retaliatory discharge, in direct violation of the Dodd-Frank Act of 2010 and other federal statutes.

After law school, Mark spent five years as an attorney at Wilmer Hale LLP, where he was a core member of the securities litigation and enforcement practice group.  He thereafter has worked at two of the most prominent securities class action firms in the New England area.  Among the notable cases he has worked on:

Mark was a lead associate representing the Ohio Public Employees Retirement System in the securities class action In re BP plc Securities Litigation, case no. 4:10-md-02185 (S.D. Tex), where he worked to recover investor losses caused by BP’s public misrepresentations regarding the severity of the oil spill resulting from the April 20, 2010 explosion onboard the Deepwater Horizon drilling rig.  This matter was settled with a $175 million award for class members.

Mark was also the lead associate representing two Massachusetts based Retirement Boards in the matter Brockton Retirement Board and Quincy Retirement Board v. Oppenheimer Global Resource Private Equity Fund I, L.P, 1:12-cv-10552 (D. Mass), which charged that defendants violated Section 12(a)(2) of the Securities Act of 1933 by misrepresenting the rate of return on an investment fund marketed to public pension boards.  This litigation resulted in significant corporate reforms to Oppenheimer’s valuation practices.

Mark has also been involved in a variety of high-profile antitrust actions, including: In re TFT-LCD (Flat Panel) Antitrust Litigation, 07-1827 (N.D. Cal) ($500 million recovered due price fixing of TFT-LCD displays); Air Cargo Shipping Services Antitrust Litigation, 06-md-1775 (E.D.N.Y.) (more than $270 million recovered due to price fixing of fuel surcharges for freight transportation); and Online DVD Rental Antitrust Litigation, 09-2029 (N.D. Cal.) (partial settlement of $27 million recovered for consumers affected by conspiracy to eliminate competition in the market for online DVD movie rentals).

In addition to class action litigation, Mark has represented clients in a broad range of commercial matters.  He is also experienced in alternative dispute resolutions and has represented clients in arbitration proceedings involving both the earn-out rights and the indemnification rights of corporate officials.
