defeasibility in law

Defeasibility in law refers to conditions that can nullify or override a legal rule or decision when certain facts or circumstances change. Think of a legal rule as a guideline that generally applies, but if specific conditions are met—like new evidence or a legal exception—the rule no longer applies or is "defeated." This concept ensures laws are flexible and fair, allowing their application to be adjusted based on particular details, making legal outcomes more just and context-sensitive.
