- In re American Express Anti-Steering Rules Antitrust Litigation – Jeanette is on the case team in this multidistrict litigation class action lawsuit consolidated in the Eastern District of New York. In that case, Hausfeld represents a class of merchant plaintiffs alleging that American Express’ Anti-Steering Rules, which prohibit merchants from steering consumers towards using other credit and charge cards to pay for purchases, unreasonably restrain interbrand price competition among credit and charge card networks thereby affecting the two-sided market.
- In re Chicago Board Options Exchange Volatility Index Manipulation Antitrust Litigation – Jeanette is involved in this multidistrict litigation class action lawsuit consolidated in the Northern District of Illinois alleging manipulation of the CBOE Volatility Index (“VIX”), known as the U.S. stock market’s “fear gauge.”
- In re Mexican Government Bonds Antitrust Litigation – Jeanette is involved in this multidistrict litigation class action lawsuit alleging manipulation of the Mexican Government Bonds market.
- District Council #16 v. Sutter Health et al. and The State of California ex rel. Duncan & Hulbert v. Sutter Health et al. – Jeanette is involved in these two cases in California State court against Sutter Health, a California-based hospital chain.
- Suffolk County Water Authority v. The Dow Chemical Company et al. and Suffolk County Water Authority v. The 3M Company et al. – Jeanette is a member of these two case teams. The cases were filed against the manufacturers of toxic chemicals that have polluted the Authority’s public supply wells, these water contamination cases allege that the defendants, who knew or should have known of the environmental risks of their defectively- designed products, must bear responsibility for the costs of treating the contaminated water and protecting the public from harm.
Children v. the Climate Crisis: Chiara Sacchi et al. v. Argentina, Brazil, France, Germany, and Turkey – In which Hausfeld and co-counsel Earthjustice represent 16 children from around the world, including Greta Thunberg and Alexandria Villaseñor, in a complaint filed before the UN Committee on the Rights of the Child alleging violations of children’s rights to life, health, and culture by five members of the G20 whose failure to reduce carbon emissions is perpetuating climate change.
- Jeanette is an active participant in the firm’s pro-bono work. Notably, she is part of the Hausfeld team which, in early 2018, filed four separate lawsuits in federal courts located in California, Massachusetts, South Carolina, and Texas, each alleging that the winner-take-all system of the electoral college violates the U.S. Constitution and distorts presidential campaigns. The multiple plaintiffs in these four cases, including the largest Latino membership organization in the U.S., LULAC, seek to establish a more democratic system of voting for the President. See Rodriguez, et al. v. Brown, et al., No. 18-cv-01422 (C.D. Cal.); Lyman, et al. v. Baker, et al., No. 18-cv-10327 (D. Ma.); Baten, et al. v.
