This paper tests the hypothesis that financially and organizationally stronger parties tend to prevail in litigation against weaker parties, either because the normative structure of the American legal system has favored “the haves,” or because judges' attitudes do, or because stronger parties have strategic and representational advantages in litigation. The study is based on a sample of 5,904 cases from sixteen state supreme courts, 1870–1970. According to our data, stronger parties, especially larger governmental units, did tend to achieve an advantage over weaker parties, but the advantage generally was rather small. The stronger parties' edge recurs in subsamples for different types of cases, time periods, and types of legal representation. It is attributed in part to the greater litigational capabilities of stronger parties.
