An unwritten constitution does not mean that nothing is written at all. Instead, it refers to a constitutional system where: There is no single formal written document called “The Constitution”. The constitution is derived from a variety of sources, including:

• • Statutes (written laws)

  • Judicial decisions

  • Conventions (traditional practices)

  • Legal documents (e.g., Magna Carta)

  • Common law

The United Kingdom is a classic example of a country with an unwritten (or partially written) constitution.
