These conventions have been explained as “rules of constitutional conduct which are regarded to be attaching by and upon those who administer constitution but which are not put into effect by courts nor by the legislators in the house of parliament. This implies that conventions or customs can be disregarded with no legal impacts whatsoever ( E.C.S Wade,1993).Further, constitutional law in the U.K does not have any privileged status in British law as it can be repealed or changed in the same style as other laws. For instance, if an action has been pronounced as “unconstitutional” it does not imply that it is “illegal and it connotes only that such action is unenforceable in the courts. In contrast to the United States, power may be exercised on legal authority and it can still be regarded as “unconstitutional” in the U.K as it is more moral than a legal decision.The U.K has a unique legal system where House of Commons, is being voted directly by people at the same time the Crown retains certain unique powers that are prerogative in nature. These prerogative powers can be exercised by the Crown unilaterally but it remains only in texts since they had not been exercised in opposition to the decision of the House of Commons. However, the constitutional rules that restrict the style in which the Crown exercises its privileged powers are mostly “non-legal” or undocumented (H. Barnett, 2006).In the U.K , legislation passed by the U.K Parliament may be regarded as “unconstitutional” and hence it could not be implemented and it is to observed that limitation on the power of parliament is non-legal (Vick, 2002).The sanction which constrains the boldest political adventurer to obey the fundamental principals of… conventions… is the fact that the breach will almost immediately bring the offender into conflict with the courts and the law of the land. – A. V. Dicey, The law of the constitution (1931)The above is being considered on two grounds in this research essay. One is on the conventions and customs that form part and parcel of any constitution and another is the treaty and foreign convention entered into by a nation and how it affects or tries infringes its constitution and if so, which will prevail is being deliberated in this research essay.
