Expert Witness & Litigation Support

Problems that occur when storing, conveying, or processing powders and other bulk solids sometimes lead to litigation.  Examples include: structural failure of silos, serious injury or death caused by solids equipment not performing as designed, inability to meet contract performance guarantees, fires or explosions when operating bulk material handling equipment.

Most litigation support is provided by Dr. John Carson, president of Jenike & Johanson, assisted by others within the firm, as required.  This team has the necessary theoretical knowledge of how bulk solids behave and over four decades of practical knowledge in real world applications.  Dr. Carson’s unique, specialized knowledge in this field is possessed by few others in the world.  Since he spends most of his time solving industrial problems — not on litigation support — Dr. Carson is able to provide seasoned advice and credible testimony.  He has assisted in nearly 100 legal matters, been deposed over 20 times, and appeared at more than ten trials.  He has been judged qualified to testify in both federal and state courts, and has also testified at arbitrations and mediations.
