Stare Decisis

Stare decisis is the principle that courts generally follow prior decisions.

Definition

Stare decisis, meaning “to stand by things decided,” encourages courts to follow precedent when similar legal questions arise.

Why It Matters

It promotes stability, predictability, consistency, and public confidence in the legal system.

How It Works

Courts compare the current case with earlier decisions and consider factors such as reliance, workability, and doctrinal consistency before departing from precedent.

History

The principle developed in common-law systems and became central to American judging.

Example

A court may follow an earlier ruling interpreting a federal statute.

Common Misconceptions

  • Precedent can never be overruled.
  • Stare decisis applies identically in every court.
  • Any earlier case is binding on every later court.
