哈特在其著作《法律的概念》中讨论了法律的开放结构,认为语言的有限指引和人类立法局限性导致了法律的不确定性,对规则怀疑论进行批判,以此提出他的裁量命题,即法律是部分地不确定或不完整的,法官应该行使有限的造法裁量权限以填充法律的漏洞。它与德沃金的“唯一正确答案”的观点分歧归根结底来源于两人对法本质问题不同的立场。 Hart discusses the open structure of law in his book The Concept of Law, arguing that the limited guidance of language and the limitation of human legislation lead to the uncertainty of the law and criticize the rule skepticism, so as to propose his discretionary proposition , That is, the law is partially uncertain or incomplete, and judges should exercise limited discretion to fill legal loopholes. Its disagreement with Dworkin’s view on “the only correct answer” stems from the different positions of the two on the issue of the law.
