Representative Matters

Tom works closely with his clients to develop and implement strategies and has successfully litigated and resolved significant cases in many areas. A selection of his representative cases includes:

  • Represented clients in environmental litigation and other matters in at least 27 states.
  • From 2013 to 2020, defended two corporations in the United States District Court trials and related U.S. Court of Appeals for the Eighth Circuit against Department of Justice (DOJ) led multi-seven figure civil penalties and cost recovery action. The cases involved numerous experts, corporate and fact witnesses, and substantial motion practice.
  • Substantially reduced major initial U.S. EPA calculated allocation share of paint manufacturer to zero via cross-examination of Milwaukee-area drum reclaimer facility manager and his Chicago route truck drivers.
  • Successfully defended a paint manufacturer in a toxic tort suit at a CERCLA site, resulting in a settlement for nuisance value in the Milwaukee area.
  • Represented a major automotive systems manufacturer in central New York State. After privately interviewing the owner of a 1970s waste oil reclaiming company, our client's share was reduced from top tier to early de minimis cash out.
  • Lead trial and strategy counsel for a transformer manufacturing company and its former corporate parent in 18 related mass toxic tort (PCB) actions venued in various state and federal jurisdictions and arising from a central Mississippi transformer manufacturing facility, with substantial removal practice, dispositive motion, Daubert challenges, and presenting and challenging of over 30 experts.
  • Represented an Alabama-based aircraft refurbisher and government contractor. Successfully negotiated a settlement with zero penalty and reduced remedial action scope and cost in response to a seven-figure RCRA penalty groundwater enforcement demand.
  • Represented a major automotive component systems manufacturer and negotiated within the existing PRP Group to reduce the client’s participation share by two-thirds without invoking formal group-wide allocation procedures.
  • Boldly opted out of de minimis settlement at potentially $100+ million Superfund site, subsequently resulting in over 90 percent decreased cost to the client and deferred assessments.
  • Criminal enforcement and environmental counsel to a prominent white-collar crime legal team defending an Indianapolis, Indiana, battery reclaiming facility plant manager, among others. Deeply involved in preparing defense expert witnesses (opinion disclosures and testimony) and cross-examination of U.S. government expert witnesses and legal briefings on Clean Water Act issues.
  • Common litigation counsel charged with identifying, adding as third parties, and litigating substantial contributions from third-party defendants while also defending major paint manufacturers in United States’ CERCLA cost recovery action.
  • Represented a heavy equipment manufacturer in a citizen's lawsuit regarding underground storage tanks and property damage. Tank removal and minimal settlement resulted from motion practice.
  • Managed PRP Group's remedy and interactions with Illinois EPA at an Illinois Superfund Site. Negotiated a favorable remedy and financed much of the site work by cashing out smaller parties.
