A constitution is not only about the composition of the various organs of government and the relations among them.  

• Part three of the Constitution of India lists the Fundamental Rights and also mentions the limits on these rights.
• In the past fifty years, the scope of rights has changed and in some respects, expanded. 

Right to Freedom

• Protection of Right to
  • freedom of speech and expression
  • assemble peacefully
  • form associations/unions
  • move freely throughout the territory of India
  • reside and settle in any part of India
  • practise any profession, or to carry on any occupation, trade or business.
• Protection in respect of conviction for offences
• Right to life and personal liberty
• Right to education
• Protection against arrest and detention in certain cases 

If a politician in one state decides to not allow labourers from other states to work in his state, then the Right to Freedom fundamental right is been violated. It is because the right to freedom allows an individual to move freely throughout the territory of India.
