PERSPECTIVES

EXPERIENCE

Antitrust/Competition

  • In re Foreign Exchange Benchmark Rates Antitrust Litigation – Reena is currently leading this high-stake lawsuit alleging a global conspiracy by some of the world’s largest financial institutions to fix and manipulate foreign exchange rates. In this case, Reena was instrumental in negotiating and drafting settlements reaching over $2.3 billion in total on behalf of investors. For its work on the case, Hausfeld received Global Competition Review’s award for “Litigation of the Year – Cartel Prosecution.”
  • In re Farm-Raised Salmon and Salmon Products Litigation – Reena is co-lead counsel in this litigation alleging a price-fixing conspiracy between the leading producers of farm-raised Atlantic Salmon.
  •  In re Hydrogen Peroxide Antitrust Litigation – Reena was one of the principal lawyers to secure settlements totaling almost $100 million in an antitrust case involving the chemical industry.
  • In re Refrigerant Compressors Antitrust Litigation – Reena represented global businesses in this alleged price-fixing case, reaching settlements of approximately $50 million.
  • Marine Hose Litigation – Reena concluded the negotiations for the final claims resulting from the first of its kind private global settlement with cartelist Parker ITR.
  • In re Manufactured Home Lot Rents Antitrust Litigation – Hausfeld is co-lead counsel in an antitrust case filed on behalf of a putative nationwide class of manufactured home residents against nine community management companies and a market data provider, Datacomp Appraisal Systems Inc. The Plaintiffs allege that the Defendants conspired to exchange competitively sensitive information and fixed the price of rents at manufactured home lots across the country from at least 2019 through the present. 

Human Rights

  • Reena is currently at the forefront of competition claims in South Africa, having worked with South African counsel in groundbreaking litigation on behalf of low-income bread consumers. This case resulted in a landmark ruling by the Supreme Court of Appeal (SCA) which determined for the first time the specific requirements for filing a collective action in South African courts.
  • Reena represented residents of Bhopal, India who were exposed to toxic wastes. These wastes contaminated the soil and drinking water surrounding the infamous Union Carbide Plant, which was the site of the 1984 gas leak that killed and injured thousands of residents.
  • Reena has been involved in litigation in both the UK and in South Africa on behalf of South African gold miners who have suffered from silicosis. In South Africa, the Johannesburg High Court certified the case as a class action against most of South Africa’s gold mining industry.  Following certification, extensive negotiations resulted in a landmark settlement in May 2018.
  • Reena also assisted in the representation of the former “comfort women,” a title given to women and girls who were forced into sexual slavery during World War II.
  • In her pro bono work, among other cases, Reena has successfully represented individuals in United States Immigration Court in political asylum proceedings.
