The purpose of this study is to analyze the status of the public policy as a defense to enforcement in the U.S and to examine its success rate. The thesis will contain suggestions to make public policy a more meaningful defense with respect to the enforcement of foreign judgments and its role in bringing about uniformity in the field of foreign judgments will be analyzed.
