Why It Matters
This article serves as a critical revision tool for GS2, mapping the substantive changes to the Constitution from 2014 to 2019. It links core syllabus topics like judicial independence (NJAC), fiscal federalism (GST), constitutional bodies (NCBC), and affirmative action (EWS) to actual constitutional amendments, which is highly relevant for both Prelims (Article 368 procedures, specific amendment details) and Mains (evaluating the impact of these amendments).
Summary
An overview of the five major Constitutional Amendment Acts passed during Prime Minister Narendra Modi's first term (2014-2019). The piece examines how these legislative shifts influenced various facets of Indian democracy, economy, and social justice. Highlights include the failed attempt to replace the collegium system via the 99th Amendment (NJAC), the resolution of territorial disputes with Bangladesh (100th Amendment), the landmark indirect tax reform through GST (101st Amendment), the empowerment of the NCBC with constitutional status (102nd Amendment), and the introduction of the 10% EWS quota (103rd Amendment).
Key Points
- The 99th Amendment Act (2014) established the National Judicial Appointments Commission (NJAC) but was struck down by the Supreme Court in 2015 for violating the basic structure doctrine (independence of the judiciary).
- The 100th Amendment Act (2015) operationalized the Land Boundary Agreement with Bangladesh, resolving historic border disputes through the exchange of enclaves.
- The 101st Amendment Act (2016) introduced the Goods and Services Tax (GST), overhauling India's indirect tax system and altering Centre-State fiscal relations.
- The 102nd Amendment Act (2018) granted constitutional status to the National Commission for Backward Classes (NCBC), giving it greater powers to safeguard marginalized communities.
- The 103rd Amendment Act (2019) introduced a 10% reservation for Economically Weaker Sections (EWS), fundamentally altering affirmative action by basing it on economic criteria.

UPSC context

A proposed six-member constitutional body designed to replace the collegium system for judicial appointments. It aimed to include executive and civil society representatives before being declared unconstitutional.
UPSC context
GS II (Judiciary). Key for debates on transparency, accountability, and executive vs. judicial primacy in appointments.
National Commission for Backward Classes (NCBC)
A constitutional body under Article 338B responsible for safeguarding the interests of backward classes. It investigates welfare safeguards and advises on socio-economic development policies.
UPSC context
GS II (Vulnerable Sections). Important for understanding institutional mechanisms for social justice and administrative oversight.
Goods and Services Tax (GST)
A comprehensive, destination-based indirect tax that replaced multiple central and state levies. It seeks to create a unified national market and eliminate the cascading effect of taxes.
UPSC context
GS III (Indian Economy). Central to fiscal policy, ease of doing business, and cooperative federalism.
Prelims Trap
Ceding Indian territory to Bangladesh under the 100th Amendment was done via an ordinary law under Article 3.
Under Article 3, Parliament alters state boundaries via ordinary law. However, ceding Indian territory to a foreign state requires a formal Constitutional Amendment under Article 368 (Berubari Union Case, 1960).
Static Concepts Connected
How does the Constitution handle the cession of territory to a foreign state?
- Article 3 limits: Under Article 3, Parliament can alter domestic boundaries, but cannot cede territory to foreign nations using an ordinary legislative process.
- Article 368 mandate: Ceding Indian territory to a foreign nation strictly requires a Constitutional Amendment under Article 368, as established in the 1960 Berubari Union Case.
- First Schedule impact: The 100th Amendment operationalized the Land Boundary Agreement by formally amending the First Schedule of the Constitution.
What key constitutional insertions were made to enable the GST regime?
- Article 246A: Inserted to grant concurrent, overriding powers to the Centre and States to levy and collect Goods and Services Tax.
- Article 279A: Established the GST Council as a joint forum of the Centre and States, heavily altering fiscal federalism dynamics.
- Article 268A repeal: Repealed to remove the explicit power of the Union to levy taxes on the sale or purchase of goods in the course of inter-state trade.
Cross-Topic Patterns
EWS & Indra Sawhney 50% ceiling
The 103rd Amendment challenged the 1992 Indra Sawhney ruling, which previously established that economic backwardness cannot be the sole criterion for reservation and capped overall quotas at 50%.
Evolution of NCBC to Constitutional status
Originally a statutory body formed in 1993, the NCBC was elevated via the 102nd Amendment (Article 338B), granting it civil court powers akin to the NCSC and NCST.
Expect a chronological matching question on recent CAAs (99-106) or a statement linking the 102nd CAA (Art 338B) to state backward lists.
