American Bar Association Toxic Tort & Environmental Law Committee of TIPS, Past Chair

BornFrankfurt, Germany, July 15, 1950

Ms. Prosser is a first-chair trial lawyer focusing her practice on the defense of high-profile toxic tort, environmental, pharmaceutical, products liability and commercial cases. She is based in California and handles cases across that state as well as across the United States.

In the area of toxic tort, pharmaceutical and products liability defense, Ms. Prosser's experience includes representing clients with diversified products ranging from chemicals (benzene, silica, adhesives, solvents, welding rods, asbestos and silicones), to engines (locomotive, jet engine, construction equipment), to pharmaceuticals (contrast agents), to medical devices (operating room equipment), to agricultural (pesticides and fertilizers), to military equipment, to industrial products (natural gas compressors) and residential appliances (stoves, refrigerators, dryers).

In the area of environmental law, Ms. Prosser has defended private and public entity clients who were target defendants in a mass tort neighborhood suit alleging soil and groundwater contamination, property damages and medical monitoring, and has also handled numerous federal CERCLA cases involving large-scale contamination sites for both public and private entities.

Ms. Prosser is a seasoned and creative trial strategist with an established track record of identifying her clients' goals, mastering complex expert issues, discrediting her opponents' liability theories, and executing an exit strategy by jury verdict, mediation resolution or arbitration award-depending on the unique aspects of each case.

February 10, 2012Downer Livestock Once Again Focus

The Supreme Court overturned a California law that required so-called downer or non-ambulatory animals to be immediately euthanized and held out of the food supply. In its decision, the United States Supreme Court held that the Federal Meat Inspection Act's express preemption provision prohibits states from imposing requirements on federally inspected slaughterhouses that are additional or different from the provisions of the Federal Meat Inspection Act, even if the requirements do not conflict.
