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.

法律的界限

法律制度的规范与决定人们在该制度内的权利和义务有关。一些不属于法律体系的规范也与之相关：外国法律体系规范、比赛、俱乐部、合同、语法等。一个法律体系的规范与仅仅与它相关的规范有什么区别？换句话说，法律的界限在哪里？文献中存在三个现有答案，分别来自 Kramer、Shapiro 和 Raz。没有一个成功。更好的答案始于区分两种类型的法律相关性：直接和间接。法律体系的规范与它直接相关。不属于法律体系的规范至多与它间接相关。因此，这两种规范的区别在于其相关性的直接性。
