A codified constitution is a constitution in which key constitutional provisions are collected within a single document, it is commonly known as a written constitution. E.g USA, Australia. Codified constitutions are:
1. Authoritative- The constitution is a 'higher law'. The constitution binds all political institutions, including those that made ordinary law.
2. Entrenched- This means that it is difficult to amend or abolish.
3. Judiciable- Because the constitution is a 'higher law', the judiciary can declare whether a law or action is constitutional or unconstitutional.
Made up of rules that are found in a variety of sources, in the absence of a single legal document or written constitution.
1.Not Authoritative- Constitutional laws enjoy the same status as ordinary laws.
2.Not Entrenched- The constitutions can be changed through the ordinary process for enacting statue law.
3.Not Judiciable- In the absence of a higher law, judges do not have a legal standard at which they declare things constitutional or unconstitutional.
