Doctrine binding courts to follow precedents from prior decisions.

Stare Decisis (Latin: 'to stand by things decided') is the common-law doctrine that courts should generally follow precedents from prior decisions in cases with similar facts, providing predictability and consistency in legal application. The doctrine descends from English common-law tradition, with foundational development through medieval English courts and substantial American adoption with substantial subsequent development. Stare decisis operates with two principal dimensions: vertical stare decisis (lower courts must follow precedents from higher courts within the same jurisdiction) and horizontal stare decisis (courts should generally follow their own prior decisions). The doctrine is substantially stronger in common-law systems than in civil-law systems (which traditionally treat precedent as persuasive rather than binding). Within common-law systems, stare decisis varies in strength: vertical stare decisis is essentially absolute (lower courts must follow higher-court precedent regardless of disagreement); horizontal stare decisis allows the same court to overrule its own prior decisions but requires substantial justification. The Supreme Court has articulated factors supporting stare decisis including reliance interests, workability, doctrinal coherence, factual evolution, and consistency with broader legal framework — most recently in Planned Parenthood v. Casey (1992) articulating substantial stare decisis test, and in subsequent cases. Recent Supreme Court terms have substantially complicated stare decisis: Dobbs v. Jackson Women's Health Organization (2022) explicitly overturned Roe v. Wade (1973) and Planned Parenthood v. Casey (1992); Students for Fair Admissions v. Harvard (2023) substantially modified the affirmative action framework from Grutter v. Bollinger (2003); and several other decisions have departed from substantial precedent. These developments have generated substantial scholarly debate about whether stare decisis remains a meaningful constraint or has become substantially case-by-case discretion.
