Judicial review is a double-edged sword. It can be exercised courageously, but prudently, to defend the rights of those politically and economically disadvantaged or to hold the line against abuses of power. On the other hand, judicial review can easily become a formidable instrument for legitimating the interests of existing political and economic elites. Can you provide examples of cases where the U. S. Supreme Court, like the court in Korea, attempted to walk the line between government power and the rights of individuals without that power?
