The norms of a legal system are relevant in deciding on people's rights and duties within that system. Some norms that are not part of a legal system are also relevant within it: norms of foreign legal systems, games, clubs, contracts, grammar, and so on. What distinguishes the norms of a legal system from the norms merely relevant within it? Where, in other words, are law's boundaries? There are three existing answers in the literature, from Kramer, Shapiro, and Raz. None succeed. A better answer starts with a distinction between two types of legal relevance: direct and indirect. Norms of a legal system are directly relevant within it. Norms that are not part of a legal system are at most indirectly relevant within it. Thus, the two types of norms are distinguished by the directness of their relevance.

This paper examines the scope of John Rawls's theory of liberty. It first develops an account of how this theory, which Rawls presents in largely abstract terms, applies in specific cases. It then argues that this account reveals that the scope of Rawls's theory of liberty is surprisingly narrow and that it does not include such seemingly obvious liberal rights as the freedom to engage in the sexual behavior of one's choice or to have access to pornography.

People have procedural rights because states are under a duty of political morality to provide them with fair procedures for settling disputes about the application of the laws. This obligation flows from the state's duty to treat each person as a free and equal member of the legal order. Yet adherence to procedural rights can impede accuracy in fact-finding, which in turn can result in poor protection for substantive rights. So the state also has a duty to provide a reasonable degree of accuracy in fact-finding. The legal order should therefore strive to improve the accuracy of fact-finding, within the constraints imposed by procedural rights people have. Nevertheless, the duty to provide reasonably accurate procedures is subordinate to the duty to provide procedural rights because the settlement of disputes among free persons must be conducted in a manner that respects their status as free persons.
