A more thorough explanation: The term “convention of the constitution” refers to an unwritten rule or practice that is followed in the interpretation and application of a constitution, even though it is not explicitly stated in the text of the constitution itself. These conventions are often based on long-standing traditions, customs, or practices that have evolved over time and are considered to be binding on those who operate within the constitutional framework. Conventions of the constitution play a significant role in shaping the functioning of a constitutional system and are considered to be an important part of constitutional law.
Example: The convention of the constitution dictates that the President must be a natural-born citizen of the United States.
