Please review again Riggs et al v Palmer et al (1889) Court of Appeals of New York as published in David Dyzenhaus & Arthur Ripstein, Law and Morality: Readings in Legal Philosophy (University of Toronto Press, 1998) 134. Please explain the role and meaning of the public policy doctrine in common law according to the court. Does morality inextricably play a role in the courts interpretative choices? How one can limit or expand the role of moral reasoning in the adjudicatory process?
