Distinct between written and un-written constitution by Johnson Yesaya.

The distinction between written and un-written constitution.

A written constitution is normally supposed to mean a document or a collection of documents in which the basic rules regarding the main organs and institutions of government are clearly laid down . A written constitution is a deliberate creation and it is a consciously planned system. In Tanzania, our constitution is a written one, all principles of operation of the state are listed in just one book passed by national assembly and assented by president Nyerere.

Unwritten constitution is not in written form, the common  practices of the state toward various matters become part of the constitution. The constitution of Britain is the best example of an unwritten constitution. Unwritten constitution is the result of long process and natural growth of political constitutions of the country. There are no single document/documents, which contain it; though many sources may be found describing it. There may be some written documents but their proportion is much smaller than the unwritten elements.
