Stare decisis, the principle of adhering to judicial precedents, forms the foundation of common law systems by ensuring consistency and predictability in legal decisions. This doctrine, rooted in Latin, requires courts to follow previous rulings in similar cases, although exceptions apply for binding or persuasive precedents.
Legal scholars and judges, including Harry Blackmun and Thurgood Marshall, have highlighted its role in safeguarding private rights and promoting judicial fairness, while others, such as Abel P. Upshur, have pointed to its adaptability within federal governance. The U.S. Supreme Court’s readiness to overturn precedents when warranted illustrates stare decisis as a flexible yet structured framework, balancing legal stability with the ability to evolve.
