The Supreme Court's use of judicial review results in changing applications of the Constitution that is sometimes referred to as the "informal amendment process." The term is misleading, however, because the only real way to change the Constitution is the formal procedure involving Congress and the States, as described in Article V. "Informal amendment" isn't amendment at all, it just represents changes to our understanding of the Constitution as expressed through case law in the American common law system.

Formal amendments are changes to the Constitution made by following the procedures outlined in Article V; they result in new written material being added to the Constitution (even if the addition actually repeals another amendment). Judicial interpretation is called the "informal amendment process" because it changes the way the Constitution is understood and applied without altering the document itself.
