Jim Wedeking

Staff Attorney

JIM WEDEKING is an environmental litigator, representing large companies in the defense of criminal and civil enforcement actions, toxic tort defense and complex civil litigation. Jim’s toxic tort work has included defending claims of product defects, failure to warn, public and private nuisance and trespass. A key aspect of Jim’s practice includes developing an involved understanding of how a client’s facilities function, given the complex scientific and technical issues that are typically the subject of litigation. These clients have included large companies in the oil and gas, electric power, chemical manufacturing, mining and agricultural industries.

Selected representations include:

  • Lead counsel for a commodities trading company in toxic tort litigation involving alleged MTBE contamination in California, New Jersey and New York.
  • Represented an electric power company in a federal criminal investigation into coal ash discharges and NPDES permit violations.
  • Defending a mining company from claims of CERCLA liability and natural resource damages allegedly related to mining activities dating back 150 years. 

Jim has significant experience aiding clients in criminal and civil investigations, including responses to grand jury subpoenas and federal agency information requests. This experience helps reduce the burden of response for clients while targeted internal investigations aid in resolving potential compliance issues. Jim’s work on environmental litigation has earned him recognition as a Rising Star in environmental litigation in 2014 and 2015 by Washington D.C. Super Lawyers magazine.
