Final answer:
The U.S. Constitution can be informally amended through legislation, executive actions, judicial interpretations, political party practices, and established customs. These processes alter the application and interpretation of the Constitution without changing its written words.
Step-by-step explanation:
The Informal Constitutional Amendment Process: The Constitution can be informally changed through the interpretation and actions of different governmental bodies without altering its text. This can be done through the following methods: Legislation: Congress can pass laws that elaborate or clarify the Constitution's brief provisions. An example of legislative expansion is the establishment of a minimum wage.
Executive Action: Actions by the President can also lead to informal amendments. An example is the use of executive orders. Judicial Review: Through its decisions, the Supreme Court can interpret and thus change the application of the Constitution. Landmark cases like Brown v. Board of Education have had this effect.
Party Practices: Political parties may develop practices that become accepted and influential over time, such as the two-term precedent set by George Washington, who served only two terms, although this was later formalized into the 22nd Amendment. Custom and Usage: Traditions that are adopted over time can shape government functions and policy, such as the President's Cabinet.
