Review Questions

• How did Lon L. Fuller's views challenge the notion of legal positivism?
  • Lon L. Fuller challenged legal positivism by arguing that law is not just a set of rules defined by social facts but also requires a moral foundation. He believed that for laws to be legitimate, they must align with ethical principles and serve social purposes. This perspective emphasizes that simply having rules does not equate to justice or good governance, as laws must also be grounded in moral reasoning.
• In what ways did Fuller’s concept of the 'inner morality of law' relate to the principles of precedent and stare decisis?
  • Fuller's concept of the 'inner morality of law' relates closely to the principles of precedent and stare decisis as it highlights the need for laws to be consistent and transparent. Stare decisis requires courts to follow established precedents, which reinforces the idea that laws should uphold moral integrity and provide predictable outcomes. Fuller argued that adherence to these principles ensures that laws are not only applied consistently but also reflect a commitment to justice and fairness.
• Evaluate how Fuller's arguments about law’s moral dimensions could influence modern legal systems' approach to precedent and stare decisis.
  • Fuller’s arguments suggest that modern legal systems should consider the moral implications behind precedents when applying stare decisis. By integrating ethical considerations into judicial decision-making, courts could ensure that their rulings promote justice and social welfare rather than just adhering to outdated rules. This shift could lead to a more dynamic interpretation of law, where judges not only follow precedents but also critically assess whether those precedents align with contemporary moral standards and societal needs.
