The United Kingdom does not have a codified constitution. However, a number of texts are considered to be constitutional, such that the "constitution of the United Kingdom" or "British constitution" may refer to a number of historical and momentous laws and principles that make up the country's body politic. Thus the term "UK constitution" is sometimes said to refer to an "unwritten" or uncodified constitution. The British constitution primarily draws from four sources: statute law (laws passed by the legislature), common law (laws established through court judgments), parliamentary conventions, and works of authority.[1] Similar to a constitutional document, it also concerns both the relationship between the individual and the state and the functioning of the legislature, the executive, and the judiciary.
Good Luck!
3/4s of the States are needed to ratify an amendment to the Constitution.
Today, this would mean that 38 states would need to approve an amendment at the state level for the amendment to be added.
