1. Many scholars and theorists have noted that post-colonial theories of law, feminist theories of law, and race-based theories of law share a common perspectivethey view law and legal theory from the position of subordinates governed by the law, but who were otherwise excluded from law-making. Please elaborate on this shared perspective, and please give an example of a theorist who might represent a post-colonial, a feminist, and a race-based approach to modern law and legal systems.
2. In his essay about judicial review, Jeremy Waldron argues against the conventional view in the United States that the federal courts, particularly the United States Supreme Court, should have the power to strike down legislation. Please explain the central arguments of his essay.
