Discuss whether today there are many legal, moral or political constraints on the power of the Westminster Parliament to pass the legislation it chooses, illustrating your answer with reference to relevant cases and statues.

Parliament has, under The English Constitution, the right to make or unmake any law whatever, and further that no person or body is recognised by The Law of England as having a right to override or set aside the legislation of Parliament. (Dicey)

        Parliamentary supremacy, this term means that the parliament is the supreme law making body in the United Kingdom and has the absolute legal right to make any law it chooses and to amend or repel existing law. This has long been taken as one of The Basic Principles of the British Constitution and serves to distinguish The British System of Government from those of most other western countries which have written constitution defining and limiting The Power of The Legislature.

        Most written constitution creates a constitutional court with the function of whether acts of the legislature are consistent with the constitution. In the United States, in the landmark ruling of Marbury V Madison 1 Cranch (545) 137(1803). The US Supreme Court held that it had the jurisdiction to decide whether an act of congress was or was not in conformity with the US constitution. Thus in the United Estates, if legislation is passed which infringes rights guaranteed by the constitution, it may be held invalid. However, in the United Kingdom, no such restrains are placed on the Parliament.

        In Madzimbamuto V Lardner-Burke (1969) 1 A.C 645, a case which arose out of the unilateral declaration of independence in 1965 by The Rhodesian Government, Lord Reid said,

‘It is often said that it would be unconstitutional for the United Kingdom to do certain things, meaning that the moral, political and other reasons against doing them are so strong that most people would regard to it as highly improper if Parliament did these things, but that does not mean that it is beyond the power of Parliament to do such things. If Parliament chose to do any of them the courts could not hold The Act of Parliament invalid.’ (Ibid P.723)

        Therefore in the UK, the supremacy of Parliament is the fundamental rule of constitutional law. In practice it means that Parliament can legislate on any matter. Then this must be taken to mean that there are no legal limitations.

        Parliament’s legislative supremacy has been challenged on a number of occasions, but generally the courts have been reluctant to declare acts of Parliament invalid.

One of the many examples of this is the case of Edinburgh and Dalkeith Railway Co V Wauchope (1842) 8 el & 10, in this case an act is challenged on the ground that when it is introduced as a bill into Parliament, notice had not been given as required by the standing orders of the House of Commons. Lord Campbell said:

All that a Court of Justice can do is to look at Parliamentary role, if an act has been passed by both houses of Parliament and received the royal assent, no Court of Justice can inquire into the manner in which it was introduced into Parliament.

        In another case a challenge made on the basis of an alleged procedural irregularity. In British Railways Board V Pickin (1974) A.C 765. Pickin owned land on either side of the railway line. Private acts of 1836 and 1845 provided that if the line was ever abandoned, the land on which it was built reverted to the owners of the adjacent land. However, this rule was abolished in 1968, by a private act which had been sponsored by The Board. Pickin claimed that The Board had fraudulently misled the Parliament when the 1968 act was passed and so the act should not be relied on. The House of Lords Held, that the court’s function was to consider and apply acts of Parliament. It was not open to a litigant to impugn the validity of statute by seeking to establish that Parliament had been misled. Nor, if Parliament had been misled, would that enable a litigant to establish a claim in equity against the other party. The court would not look into the manner in which Parliament had exercised its function.

        It seems, courts may not even question an act if it is inconsistent with international law. This was demonstrated in the case of Cheney V Coun (1968) 1 All ER 779: a tax payer challenged the validity of The Finance Act 1964 arguing that it was in conflict with the international Geneva conventions on warfare incorporated into UK law as the Geneva Convections Act 1957. It was claimed that this 1964 act was contrary to international law, because part of the tax collected would go towards the manufacture of nuclear weapons. Ungoed- Thomas J said that ‘what the statue itself ...
