There is a debate because the UK has parts of its Constitution codified ( written ) and uncodified ( not written ) . If the constitution is uncodified , then sources for the agreement are still accessible , they are just written in different various political books or tradition , instead of written all in one place like a codified Constitution .
The terms written constitution and codified constitution are often used interchangeably , as are unwritten constitution and uncodified constitution , although this usage is technically inaccurate .
