Public policy is an unavoidable factor in any jurisdiction, as it forms the cornerstone of a legal system. At the same time, giving enormous importance to public policy can erode the legal system itself, especially alternative dispute resolution. Hence it can be defined as a “necessary evil” or a “double-ended sword.” The idea of this paper is to introduce a theory which aims at striking a balance or harmonization Between Public policy and the enforcement of foreign arbitration award. The theory is supported by a comparative study, which concludes that advanced countries like USA have been successful in taming this unruly horse.
