The correct answer is Change in Union List. Explanation & Key Takeaways: • Under Article 368(2) of the Constitution of India, an amendment that results in a change in the Union List requires ratification by at least half of the State Legislatures in addition to approval by a special majority of Parliament. • The Union List is a part of the Seventh Schedule and contains subjects on which only the central government can legislate, such as defense, foreign affairs, atomic energy, and railways. • The requirement for state ratification ensures that amendments affecting the Union List maintain the federal structure and secure state participation in decision-making. • This provision reflects the balance between the central and state governments, ensuring that critical matters impacting federalism are not unilaterally decided by Parliament. • Examples of amendments requiring state ratification include changes in legislative powers and adjustments to the jurisdiction of the Union List. Related Concepts: • Inclusion of new languages in the Eighth Schedule: • The Eighth Schedule of the Constitution lists the official languages recognized by the Indian government. • Currently, there are 22 languages listed in the Eighth Schedule, including Hindi, Bengali, Telugu, Marathi, Tamil, Urdu, Gujarati, and others. • Adding a new language to the Eighth Schedule does not require ratification by the states; it can be done through a constitutional amendment passed by a special majority in Parliament. • The inclusion of languages in this schedule is aimed at promoting linguistic diversity and ensuring representation for various linguistic communities. • Amendments to the Directive Principles of State Policy: • The Directive Principles of State Policy (DPSP) are guidelines for the central and state governments to frame policies and laws, enshrined in Part IV of the Constitution. • These principles are non-justiciable, meaning they cannot be enforced by courts, but they are fundamental in governance and policy-making. • Amendments to the DPSP only require approval by a special majority in Parliament and do not necessitate ratification by state legislatures. • Examples of DPSPs include promoting equitable distribution of wealth, providing free legal aid, and protecting the environment. • Alteration of names of existing states: • Changes in the name of an existing state are governed by Article 3 of the Constitution, which allows Parliament to enact laws for the reorganization of states. • Such changes do not fall under Article 368(2) and do not require ratification by state legislatures. • Before making such changes, the President must refer the proposal to the legislature of the concerned state for its views; however, the final decision rests with Parliament. • Examples include the renaming of Madras to Tamil Nadu and Bombay to Maharashtra.
