What are some examples of an informal amendment to the US constitution?

Informal amendments to the U.S. Constitution refer to changes in interpretation or application without altering the text. Examples include judicial interpretations, such as Supreme Court decisions that expand civil rights or redefine federal powers, like Brown v. Board of Education, which desegregated schools. Additionally, changes in societal norms and customs, such as the establishment of presidential term limits through tradition before the 22nd Amendment, also reflect informal amendments. These adaptations demonstrate how the Constitution evolves alongside American society.
