What's the difference between legislation and the UK Constitution?

Constitutional law sets limits to power and is in place to protect citizens' liberties and fundamental rights from the powerful but was not merged into one document.

Laws in violation of the Constitution are not valid and cannot be enforced by the courts, and this also applies to acts of Parliament. Parliament can add to the Constitution but are unable to change, alter, or amend it. And, while judges can't officially remove a law, they can decide how it will be interpreted or even declare it invalid.

Laws are made by Parliament and other authorities under powers given to them by the revelent statutes; case law is made by judges; precedent is made by the courts; constitutional law was formed throughout UK history and is amended by the courts; EU law was made by the European Commission; and international law consists of different treaties, ICJ rulings, UN decisions, and deals with other nations.

The UK does have a written Constitution, and it's untrue to say that it doesn't. However, it can't be found in a single document and may be hard to understand.
