A constitution is a set of rules through which a country or state operates. Some countries have unwritten constitutions which means there is no formal constitution written in one particular document. Their constitutional rules are originated from a number of sources. Britain sources its constitution from a number of important statutes, or laws, as well as principles decided in legal cases and conventions. New Zealand and Israel are two other countries that do not have formal written constitutions. Other nations have formal written constitutions in which the structure of government is defined and the respective powers of the nation and the states are written in one single document. These systems may also include unwritten conventions and constitutional law which can inform how the constitution is interpreted. Australia, India and the United States are examples of countries with a written constitution.
