Case Studies

Expert Witnessing

Expert witnessing has two broad categories including fact witness, which is based on our research, and material witness, which is based on us being at the scene. Expert material witnessing (including 30b6 - “Person Most Knowledgeable”) is based on historical research of risk management and product liability, environmental liability, fact-finding and historical information. We have testified in over 50 federal and state court cases and have delivered depositions in over 300 cases. Our experts have testified on the following topics:

  • Maritime and Aircraft Engineering History
  • Government Specifications & Standards, Policies, Procedures, Practices and Doctrine
  • Government Purchasing and Contracting Practices and Procedures
  • Government Practices and Procedures for Safety and Industrial Health

Product Liability

To determine if a client’s product was present, and/or establish alternative sources of potential exposure or assist in development of a government contractor defense, our research and analyst teams examine the following types of documents:

  • Correspondence and Reports
  • Specifications and Standards
  • Ship, Aircraft, Machinery, and Building Plans
  • Maps and Charts
  • Still and Motion Pictures...

Fact-finding Historical Research

Finding all of the documents that are relevant to your specific project is neither intuitive nor straightforward, even for an experienced researcher. The indices of these archives are based on filing systems that have not been used for decades. Learning how to locate files containing the most important relevant documents for a case takes training and experience. However, locating and retrieving relevant documents is less than half what it takes to harness the power of historical research...

Environmental Liability

McCaffery & Associates has located historical documents to assist attorneys defending a client in Environmental Protection Agency (EPA) Superfund site cost allocation negotiations. The development of historical background relating to the source of contamination by polychlorinated biphenyls (PCB) and other toxic chemicals that persist in the environment from shipbuilding and ship repair activities required detailed research into materials used in these businesses.
