Doctrine of the Separation of Powers

Although of great antiquity the modern basis for the doctrine of the

separation of powers can be traced back to the writings of

commentators such as John Locke, who in one of his books written in

1690 observed that "the three organs of government must not get in one

hand." The doctrine was further examined by the French jurist

Montesquieu who based his exposition on the British constitution of

the early 18th Century. In simple terms the doctrine recognises three

functions of government, namely legislative, executive and judicial.

In its purest form the doctrine holds that each of these three

functions should be vested in separate organs of government, with no

overlap, as to concentrate more than one function in any one organ

presents a threat to individual liberty. If the doctrine is followed

the same persons should not form part of more than one organ. For

example ministers should not sit in parliament. One organ should not

exercise the functions of another.

In the United States Constitution of 1787 separation of powers was

clearly expressed. Each of the three primary constitutional functions

was vested in a distinct organ. Legislative power was vested in

Congress consisting of a House of Representatives and a Senate,

executive power was vested in the President and judicial power was

vested in the Supreme Court and other federal courts as established by

Congress.

The president of the USAholds office for four years and does not need

States. Rather both Law Lords are speaking in support of a well

established convention of the UK Constitution, namely that Parliament

makes the law and the judiciary interprets it. This convention derives

from the concept of Parliamentary sovereignty in a system where the

legislature is elected and accountable and in which the judiciary is

required to be impartial and independent in the application of law.

All in all it would only be fair to say that the doctrine of

separation of powers is necessary in controlling the delegation of

power among organs of government and ensuring the proper use of that

power. We have examined the US and the British separation of power and

although in the US things are clearer, we can say that power is

properly controlled in both cases. If it wasn't results would have

been obvious.
