Our product liability, toxic exposure, and mass tort law practice focuses on the management and litigation of complex, high stakes liability matters arising from the production and sale of allegedly defective products and exposure to allegedly harmful substances. Because such matters may not be confined to one court or one jurisdiction, they often require strategic coordination by sophisticated national counsel to limit liability, achieve efficiency, and avoid the pitfalls of a disjointed defense conducted independently by multiple counsel. The firm’s founder, David R. Scheidemantle, has been involved in such representations since the 1980s, when he was part of a team defending a manufacturer of asbestos-containing fireproofing in approximately 150 litigations nationwide, involving thousands of buildings, including virtually every public school and public building and multiple bridges, tunnels, and office buildings in the City of New York.

Product liability matters must be managed and addressed as early as possible after the client has discovered a possible issue. We regularly counsel clients in a variety of industries on handling consumer or customer complaints immediately upon their inception to avoid litigation if possible and to lay the groundwork for a successful defense if the matter proceeds. Through a strategic and, if necessary, aggressive approach, we have been able to dispose of many claims without the payment of any settlement funds by our clients, even when litigation proceeds against other parties.

We also provide legal advice and support to clients for the reformulation or alteration of products to avoid future claims and assist in developing and implementing internal procedures, such as instituting a consumer product safety committee, to avoid claims and adhere to regulatory requirements.

A coordinated defense of product liability and mass tort matters requires not only the top-notch legal skills possessed by our litigators but also proactive management of all aspects of the matter, from risk handling and insurance coverage to customer issues, public relations, and governmental lobbying. As a result of the philosophy and approach we bring to this area of the practice, clients often call upon us to address client problems that other assigned counsel have been unable to solve.

  • Successful resolution of product defect litigation in Toronto, where plaintiff initially sought $1.5 million, then, during the principal’s testimony, reduced the amount claimed to approximately $400,000, leading to a settlement for much less.
  • Defended and obtained dismissal of the alleged manufacturer of shock absorbers in an action arising out of the nationally reported collision between a van and a truck in Texas, in which 16 passengers in the van were killed while on their way from Los Angeles to a family reunion in Mississippi.
