OVERVIEW
Jeannine joined the firm upon its inception in 2008, and her practice focuses primarily on private enforcement of federal and state antitrust laws and data privacy.
Jeannine brings to her legal work nearly two decades of experience in public policy spanning a wide range of legislative and regulatory fields, including agriculture, food safety, telecommunications, and financial services, among others, advocating for consumer protection. For nearly five years, she worked as a legislative assistant for two United States Senators. As a Senior Policy Analyst for Consumer Reports, she advocated for consumer interests before Congress and federal agencies, testifying before congressional committees, appearing as a speaker at Federal Trade Commission events, and presenting oral and written testimony to federal regulatory agencies. Jeannine also served as an appointed member of two federal advisory committees related to pesticide safety. Between stints at Consumers Union, she served as the Vice President of Domestic Affairs for the National Cooperative Business Association, representing member-owned consumer, producer, and purchasing cooperatives. From 2010 to 2011, Jeannine clerked for the Honorable Cynthia M. Rufe, United States District Court Judge, Eastern District of Pennsylvania.
Jeannine is adept and experienced in managing all aspects and phases of e-discovery, the complex process of preserving, discovering, producing, and analyzing electronically stored information (ESI). She routinely navigates detailed, complex and contentious ESI issues from dispute to resolution, including briefing and arguing e-discovery motions when necessary. An active member of the Sedona Conference’s Working Group on Electronic Document Retention and Production and its Technology Resource Panel, Jeannine counsels Hausfeld’s litigation teams in negotiations relating to preservation, search, and production of ESI in cases often involving dozens of defendants, negotiates ESI search methodologies, database disclosures and productions, and manages complex document reviews using advanced review analytics to speed discovery.

Consumer Protection
- Hale v. State Farm Mutual Auto Insurance – Hale grew out of the 1997 Avery v. State Farm litigation which alleged breach of contract related to non‑OEM auto parts in vehicle repairs, in which a certified class of about 4.7 million insureds won a $1 billion jury verdict. That verdict was overturned by the Illinois Supreme Court shortly after Illinois Supreme Court Judge Karmeier was elected to the office. Hale alleged that State Farm unlawfully conspired to secure the election of the Judge (including through improper campaign contributions) for the purpose of overturning the jury verdict. The parties settled the matter for $250 million.

Odin Properties LLC et al. – Hausfeld serves as co-lead counsel representing tenants of Bentley Manor in a class action lawsuit against one of Philadelphia’s largest landlords, challenging unsafe conditions and unlawful rent collection despite known safety violations.

Human Rights
- Kiobel v. Royal Dutch Petroleum – Jeannine and Hausfeld served as counsel to amicus Nobel prize winning economist Joseph E. Stiglitz in support of plaintiffs in Kiobel v. Royal Dutch Petroleum before the Supreme Court of the United States, in which the plaintiffs alleged domestic and foreign corporations aided and abetted torture, rape, and other violations of international human rights committed by the Nigerian government against its people. At issue on appeal to the Supreme Court was, among other issues, whether corporations could be held liable for violation of internationally recognized human rights under the Alien Tort Statute. Amici argued that the economics and policy arguments against such liability were unfounded and that corporate liability would advance rather than deter investment in developing countries and promote compliance with international human rights norms.
- Nestle v. Doe – Jeannine and Hausfeld served as counsel to amici Oxfam USA and Columbia University economics professors Joseph Stiglitz and Geoffrey Heal in support of plaintiffs in Nestle v. Doe before the Supreme Court of the United States. Plaintiffs in that case alleged certain corporations aided and abetted forced child labor on cocoa plantations in violation of international human rights norms. Amici expanded upon the economic arguments in the Stiglitz amicus brief in Kiobel and argued that liability would not deter proactive efforts by corporations to invest in measures designed to prevent human rights violations.
