Some philosophers and political scientists make a distinction between claim rights and liberty rights. A claim right is a right which entails responsibilities, duties, or obligations on other parties regarding the right-holder. In contrast, a liberty right is a right which does not entail obligations on other parties, but rather only freedom or permission for the right-holder. The distinction between these two senses of "rights" originates in American jurist Wesley Newcomb Hohfeld's analysis thereof in his seminal work Fundamental Legal Conceptions, As Applied in Judicial Reasoning and Other Legal Essays.
