OVERVIEW
Reena Gambhir, a founding lawyer of the firm, is a partner in the Washington, DC office, a member of the firm's Management Committee, and the firm's People and . She advocates for clients harmed by corporate wrongdoing—from investors who suffered anticompetitive harm at the hands of global banks to residents of vulnerable communities being subjected to anticompetitive rent increases. She brings that same leadership and advocacy inward, working to ensure that opportunity and belonging are woven into how the firm hires, manages, develops, and empowers its people.
Reena has played a leading role in some of the largest and most complex antitrust cases in the United States, including helping to secure settlements of over $2.3 billion on behalf of investors against some of the world's largest banks. She currently represents residents of manufactured home lots who allege a conspiracy among landlords to artificially inflate and fix rent prices. She also represents hospitals in an antitrust action against Intuitive Surgical, alleging that it used its monopoly over da Vinci surgical robots to impose anticompetitive restrictions on instrument reuse, repair, and servicing—artificially inflating the cost of robotic surgery.
In addition to her antitrust work, Reena practices in the areas of international environmental threats and human rights, including representing residents of Bhopal, India, who were exposed to toxic waste surrounding the Union Carbide plant following the 1984 gas leak; South African gold miners who suffered occupational lung disease as a result of oppressive mining conditions; and cities and states seeking to hold the firearm industry accountable for its failure to implement reasonable controls to reduce preventable gun violence.
Reena also co-leads the firm's Pro Bono Committee and serves on the Hiring, Global Business Development and Marketing Committees.

EXPERIENCE
Antitrust/Competition
- In re Da Vinci Surgical Robot Antitrust Litigation – Hausfeld represents a certified class of hospitals and other healthcare providers alleging that Intuitive Surgical used its dominance over da Vinci robots to impose anticompetitive restrictions, blocking third-party reuse, repair, and servicing of the robots and their EndoWrist instruments and artificially inflating the cost of robotic surgery.
- 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 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 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.

- In her pro bono work, among other cases, Reena has successfully represented individuals in United States Immigration Court in political asylum proceedings.

- City of Philadelphia and Commonwealth of Pennsylvania v. Glock, Inc. – Hausfeld serves as lead counsel to the City of Philadelphia and the Philadelphia District Attorney’s Office, in partnership with the Giffords Law Center, in this consumer‑protection action against Glock, Inc. alleging deceptive marketing that promotes illegal “Glock switches” and misleads civilians about the legality of fully automatic weapons, seeking civil penalties, compensatory damages, and equitable relief that addresses the public health and safety harms from machine‑gun‑enabled gun violence.
