Michael Giannotto is a senior partner in Goodwin Procter's Business Litigation and Environmental Groups. Mr. Giannotto is a nationally recognized expert in environmental issues impacting domestic and international hardrock mining companies and in bankruptcy and bad faith litigation for major insurance companies. He specializes in counseling and complex litigation in several areas, including environmental law, toxic torts and insurance disputes. Mr. Giannotto has tried many cases to judgment, and has briefed and argued numerous cases before federal and state appellate courts.

Mr. Giannotto is annually recognized for his mining and environmental work by U.S. News-Best Lawyers and Chambers USA, where one client noted he “is the most knowledgeable individual anywhere when it comes to the Resource Conservation and Recovery Act and its application to mining.”

For more than 35 years, Mr. Giannotto has advised and litigated on behalf of numerous corporations and trade associations involved in hardrock mining, manufacturing and defense contracting in connection with all of the major federal environmental laws and their state analogues. These include the Resource Conservation and Recovery Act, Clean Water Act, Comprehensive Environmental Response, Compensation and Liability Act, Toxic Substances Control Act, National Environmental Policy Act, Emergency Planning and Community Right To Know Act, and Federal Land Policy and Management Act.

Mr. Giannotto was part of a team that successfully litigated the first CERCLA case brought by a State to go to trial (Colorado v. Idarado Mining Company). He has represented the mining industry or individual mining companies in connection with every significant rulemaking by the EPA or the Department of the Interior, and every significant legislative proposal by the Congress, since the early 1980s relating to the environmental obligations or liabilities of hardrock mining companies.

Mr. Giannotto also has long litigated toxic tort and complex insurance matters. He has represented insurers in several mass tort bankruptcies and in numerous class- and mass-actions throughout the country alleging insurer bad faith. He has also litigated coverage disputes and disputes with governmental entities over reimbursement of insurance costs under the National Defense Projects Rating Plan. Mr. Giannotto's toxic tort cases have involved product-created toxic torts (such as asbestos-related injuries) as well as environmental toxic torts (such as releases to the environment from manufacturing facilities).

Mr. Giannotto’s significant clients include Newmont Mining Corporation, Mitsubishi/Mitsubishi Materials Corporation, CNA Financial, Resolute Management, Antofagasta Minerals, National Mining Association, Nevada Mining Association, United States Aviation Underwriters and Nevada Ready Mix Corporation.
