Unit 11.2: Landmark Amendments – 42nd, 44th, 61st, 101st (GST).

Introduction & Significance

The 42nd, 44th, 61st and 101st Amendments are among the most important and frequently asked constitutional amendments in competitive exams. They represent major shifts during and after the Emergency period (42nd & 44th), voting age reduction (61st), and landmark economic federalism reform (101st – GST).

• Exam Weightage: Extremely high – 4–8 questions combined in SSC CGL/CHSL/MTS (focus on changes made, articles affected, reversal of provisions); 2–5 in RRB NTPC/ALP/JE; very high in State PSCs (especially 42nd/44th misuse & 101st federal impact).
• Significance: 42nd (1976) is called “Mini-Constitution” due to sweeping changes; 44th (1978) is the “corrective” amendment; 61st (1989) democratized youth participation; 101st (2016) created world’s largest indirect tax regime (GST).
• Current Relevance (Feb 2026): 42nd/44th still debated in context of federalism erosion fears (e.g., misuse of central laws like BNS/BNSS/BSA in states); 101st GST continues to be litigated (compensation period ended 2022, extension demands in 2025–26); no direct link to 106th Amendment delay but both reflect Centre’s role in major structural changes.
