Examine the implications of the doctrine of the separation of powers and the concept of the rule of law for the exercising of prerogative power.

Separation of powers is a doctrine that each branch of the government is separate from the other and has its own unique powers that other branches of the government could not intervene. This concept is known to have been first formulated by Charles de Secondat, Baron de Montesquieu (January 18, 1689 - February 10, 1755)1 was a French politician that articulated the theory of the separation of powers. The separation of powers is between the branches of the Legislative, Executive and the Judicial systems. In the United States these branches differ from the England, for instance Congress as the legislative has sole power to declare war under the written constitution. In the case of the President the executive, no constitution law gives him the right to declare war but power to give orders and strategies if war is declared. If one branch were to interfere with the others duties, the situation would undergo judicial review for violating the separation of powers doctrine. The legislative has limited power under this doctrine, for example, the head of the executive (the president) has power to veto legislation. The judicial branch is their to keep them in check by examining legislation to ensure it is compatible with the constitution. If not, during judicial review legislation can be overridden.

The concept of the separation of powers is different in the United Kingdom, the UK has unwritten2 constitution were as most countries have a written constitution like the United States. In England the concept of having a Legislative, Executive and Judicial system still follows in a different manner to the US. The legislative in England is the government and it has the power to adopt laws as it sees fit. The legislature known as Parliament in the UK (or general assembly, senate or congress depending on the country) is formally supreme and appoints the executive. In the case of the Executive branch in England, this is the Lord Chancellor's division and his head of this branch. They are responsible for enforcing or executing laws passed on by parliament. The system becomes confusing in terms of the separation of powers, as the Lord Chancellor (head of executive power) is also the main power in the Judiciary. The judicial division is responsible for the interruption and the adjudication of laws passed on by parliament. The judiciary revolves around a hierarchy of courts and the two main courts in England are the House of Lords (HL) and European Court of Human Rights (ECHR). The Lord Chancellor sits as the second head on the bench of the HL and sits in the House of Commons as an MP. This can be seen as a breach in the separation of powers as the legislative, executive and judiciary interact through this main body. The Lord Chancellor not only has the power to see that judges are appointed by referring them to the Prime Minster but can also influence whether they go further up the hierarchy.

No current or past strict separation of powers has ever existed in the English constitution assigning constitutional laws to the different organs, referring to the legislative, executive and judicial bodies. Theoretical analysis has shown that no serious checks or balances are devised between these bodies of power. Development of public institutions has been mainly of empirical in that the Crown has always been a key element. The executive as the Queens government (Her Majesty's ministers), the legislative as the Queens parliament (throne in the House of Lords, royal assent to Bills) and the judiciary as the Royal Courts ...
