A codified constitution is a set of rules/ gudelines put in place to restrict Parliament and stop them breeching Civil Liverties, also availiable to the greater public. A constitutional law is higher than any other law.
An uncodified constitution is the opposite, it is not written in one single document but found in a variety of places, statute law, common law, codes/ conventions and EU law.
For/ against an uncodified Constitution
It is flexible
An alternative may be worse, in America where the constituion is codified judges hold a lot of power, judges are unelected and socially unrepresentative.
A reform is unnecessary
Civil rights are not currently presented
GVMT is unerestrained
can result in elective dictatorship
