 Dear students, we are studying the course Labour Policy Pakistan and the topic is definition of constitution by Barrister Eji Chaudhary. Question arises, why we are studying definition of constitution? Dear students, constitution is the supreme document of the land and the citizens of Pakistan are called the constitution by the supreme law which regulates them. The reason for the constitution is that it relates to any factors of production. Like factors of production are land, labour, capital, organization. So its rights are to be stemmed from the constitution. The regulations to be regulated from the constitution are to be stemmed from the constitution. Therefore Labour Policy has a lot of relation with the fundamental rights. The laws are made by the parliament, the president is involved, provincial assemblies are involved, and the concerned departments are involved. All these come from the constitution. So Labour Policy also has a very deep relation with the constitution. Therefore for those who are also studying the course of Labour Policy, it is very important to understand the definition of constitution. Before we discuss the definition given by Barrister Eji Chaudhary, let us know who Barrister Eji Chaudhary is. Barrister Eji Chaudhary is the author of the book, Lectures on Constitutional Law. Barrister has been a great researcher, scholar and philosopher. His research-oriented book is very popular and is taught in LLM programs. Barrister is graduated from Leeds University and is a great researcher and philosopher. His definition of constitution is considered to be a very important definition. Let us see. A document having a special legal sanctity which sets out the framework and the principal functions of the Organs of Government of a State. It has principles of policy and it has a lot of context and content available. This is a special legal document and it has a sanctity and enforcement. And how is enforcement done? This is a supreme document of the land and we can call it the supreme contract of the land. And behind it is the will of people. Therefore, it has a legal sanctity and anyone who is a citizen of Pakistan has to accept it. Apart from this, the constitution is also related to the Organs of State. What are the Organs of State? Legislature, Executive, Judiciary. All these powers are derived from the constitution. Legislation has to be made legal and executive has to be implemented. Judiciary has to be implemented so that if there is a conflict, then the judiciary adjudicates upon and decides upon it. And the judiciary is said to be the guardian of the constitution. Dear students, the constitution is the supreme law of the land, the fundamental law from which all public authorities derive their powers. All laws, their validity and all subjects, their rights. In this, all laws, their validity and all subjects, their rights is a very important topic. Subjects, what does it mean here? Subjects are citizens. And if a citizen is without rights, then it is not understood. Our constitution gives some basic rights to citizens. This means that you and I take our basic rights from the constitution. And the fundamental rights in the constitution are available. Regarding the fundamental rights, I will tell you that these rights cannot be taken from the government. These rights by all means are available to citizens of Pakistan. And where are they stemming from, and from the constitution? These slides in front of you have some words that have been given as documents, legal sanctity, framework, organs of government, supreme law of the land. These are given as important terminologies and they have a special legal meaning. So if you come across a term related to law, then first you have to open a black slot dictionary and then you have to use some other source to understand the meaning of that word. Here, a terminology is being given as public authority. This is very important to understand who public authority is referring to. Public authority is basically referring to the government. So the government responsible for the implementation of law is called public authority. So all these authorities which the government exercises and uses, these are all stemmed from the constitution. I hope you have understood the topic.
