The Fundamental Rights are meant for promoting the idea of political democracy.  

• They operate as limitations on the tyranny of the executive and arbitrary laws of the legislature.  
• They are justiciable in nature, that is, they are enforceable by the courts for their violation.  

• Further, they are not sacrosanct and can be curtailed or repealed by the Parliament through a constitutional amendment act.  
• They can also be suspended during the operation of a National Emergency except the rights guaranteed by Articles 20 and 21.
