What is Ratification?

Ratification

Quick Answer

Ratification is the formal approval of an agreement or amendment, typically by a vote. In the context of law, it often refers to the process by which a legislative body confirms a treaty or constitutional amendment.

Overview

Ratification is an essential step in the legal process, particularly in constitutional law. It involves the formal acceptance of a proposed agreement, such as a treaty or an amendment to the constitution, by the relevant authority, which is usually a legislative body. This step is crucial because it ensures that the agreement has the backing of the governing body and reflects the will of the people or their representatives. The process of ratification can vary depending on the type of agreement and the laws of the jurisdiction involved. For example, in the United States, the Constitution requires that treaties negotiated by the President must be ratified by a two-thirds majority in the Senate. This requirement helps to prevent any single branch of government from having too much power and ensures a system of checks and balances. Ratification matters because it legitimizes agreements and amendments, making them enforceable under the law. A real-world example is the ratification of the 19th Amendment to the U.S. Constitution, which granted women the right to vote. This amendment was ratified in 1920 after a long struggle for women's suffrage and represents a significant change in American law and society, highlighting how ratification can lead to important legal and social advancements.
