This subseries is further divided into four sections - two major cases and two groups of similar cases. Major cases are: USA v. Hugh Bryson, and Lawrence Parker et al v. J. A. Lester et al, a class-action suit challenging the waterfront screening program (Magnuson Act). There are two groups of cases: litigation by shipping companies over "breach of contract," and court cases filed by expelled members (also known as the Dirty Dozen).
