Amendment of the Constitution by Special Majority and Ratification by States

 If an amendment of the Constitution seeks to make any change in articles relating to— 

• The election of the President; or
• The extent of the executive power of the Union and the States; or
• The Supreme Court and the High Courts; or 
• Distribution of legislative powers between the Union and the States; or
• Representation of States in Parliament; or 
• The very procedure for amendment as specified in the Constitution; 

The amendment, after it is passed by the special majority, has also to be ratified by Legislatures of not less than one-half of the States by resolutions to that effect passed by those Legislatures before the Bill making provision for such an amendment is presented to the President for assent. 

The Constitution does not contemplate any time-limit within which the States must signify their ratification or disapproval of the amendments referred to them
