1. A written constitution is unneccessary
- The current system has a number of balances and checks built into it (i.e. there is a degree of balance between the executive, legislature and judiciary).
- Opposition within Parliament or outside pressure sometimes force the government's hand (e.g. poll tax).
- Judgments in the courts may curb government excesses.
2. A written constitution is undesirable
- It would mean that any dispute over the strucutre and powers of government, the relationship between different parts of government and the relationship between government and citizen would be settled by a court (l.e. power would be transferred from the elected executive to the unelected judiciary).
- The judiciary would have the power to declare laws and actions unconstitutional (i.e. judges would have to make political decisions).
3. A written constitution is unachievable
- It would be difficult to gain a consensus about what exactly should be written down in the constitution.
- Under the existing consitution there is no way of introducing a new constitution. There is no body that can authorsise or legitimise a new constitution.
- An Act of Parliament creating a new constitution or stipulating the procedures for creating one would derive its legitimacy from the doctrine which it sought to destroy. The one thing that Parliament cannot do is use itsp ower under the doctrine of parliamentary sovereignty to destroy that doctrine, because is legitimacy to do so derives from the very power which it seeks to destroy.
- We would have to create a new, written constitution from scratch and disavow our existing constitution. This would cause constitutional and political turmoil.

1. To protect against arbitrary government
- The main argument in favour of a written constitution is that it would keep in check the power of the executive. Those who support a written constitution, therefore, tend to argue that there is a need to limit government in Britain and that codifying the constitution is the best means to this end.
- A written constitution would describe and entrench: the structure and powers of government; the relationship between different parts of government; and the relationship between government and citizen.
- It would prevent arbitrary government since any disputes would be solved by (new) constitutional judicial procedures.
Lord Halisham, 1976 - GB an elective dictatorship. Curb power of the executive by writing down exactly where its powers lie.
2. To protect citizens' rights
- There is the idea that citizens' rights can only be properly protected if they are entrenched in a written constitution.
- At present, a government with an overall majority can add or remove citizens' rights simply by introducing a Bill and relying on its parliamentary majority to pass it.
Criminal Justice Act (1994) - restricts the right of people to protest and specifically targets minorities such as squatters and hunt saboteurs.
- Under a written constitution, the government would not be able to introduce legislation targeting minorities in this way or restricting citizens' rights without amending the constitution (a difficult and lengthy process).
3. To bring the constitution up to date
- Parliamentary sovereignty profoundly affected by EU membership
-- No longer fully intact so need for a new constitutional settlement
- Powers are being devolved to the new assemblies in Northern Ireland, Scotland and Wales
-- Constitutional relationship between the centre and the regions will need to be redefined, requiring a new constitutional settlement.
4. To move into line with the rest of the EU
The UK is the only country in the EU without a written constitution.
The UK constitution would be classified as unwritten/uncodified, flexible, parlimentary and unitary.
The US constitution would be classified as written/codified, rigid, republican, presidential and federal.
